**When it comes to designing and developing cars that are not only efficient but also environmentally friendly, one of the most crucial factors is understanding and optimizing the aerodynamics. In the race to reduce fuel consumption and pollutant emissions, we need tools that can accurately predict the aerodynamic performance of vehicles. That's where NablaFlow's AeroCloud comes into play. But, how can we be sure that this advanced CFD (computational fluid dynamics) tool is up to the task? The answer lies in validation.** 
In this blog post, we'll dive into two fascinating validation cases that demonstrate AeroCloud's ability to accurately calculate the drag coefficient of various car models. The first case deals with the widely used DrivAer model, while the second case focuses on a high-performance-type vehicle with modifications to the DrivAer model. These validation studies are vital steps in ensuring the reliability of the simulations and ultimately, the success of the product. So, buckle up and let's explore the world of accurate aerodynamics!
 
## Introducing the DrivAer Model

![Drivaer_Model_picture.png](https://nablaflow-cms-uploads-production.s3.eu-west-1.amazonaws.com/Drivaer_Model_picture_3587aa98d9.png)
_The DrivAer model_

To put AeroCloud's drag coefficient calculations to the test, we turned to the DrivAer model, an open-source benchmark model developed at TU-Munich [1]. This model is based on a combination of two series cars and offers a more detailed geometry than other models commonly used in academia, such as the Ahmed or SAE body. The DrivAer model is also modular, featuring exchangeable rear ends, underbody, and wheel geometries, which makes it an ideal platform for investigating realistic flow features and their nonlinear interactions in various car configurations [1]. This versatility allows us to examine how AeroCloud (pro version) performs across different car configurations, which is essential in understanding its accuracy.

### The Validation Process: Comparing AeroCloud with Real-world Experiments

![landscape.png](https://nablaflow-cms-uploads-production.s3.eu-west-1.amazonaws.com/landscape_2274c10652.png)
_Streamlines over the DrivAer model extracted from the AeroCloud simulation_

To validate AeroCloud's drag coefficient calculations, we compared its results with real-world experimental data from studies conducted at various wind tunnel facilities. These studies include the work of Varney et al. [2], which focuses on the validation of numerical methods, as well as tests conducted at the TUM wind tunnel in Munich [3], where the DrivAer model was developed [1], and the University of Stuttgart Göttingen-type wind tunnel [4]. By examining different car configurations, we could gauge how well AeroCloud was able to capture the aerodynamic behavior of each variant. The goal was to see how closely the simulations matched the experimental results, which would demonstrate the tool's accuracy and reliability.
 
### Delving Deeper: The Numbers Behind AeroCloud's Remarkable Accuracy

To truly appreciate the accuracy of AeroCloud's drag coefficient calculations, let's take a closer look at the actual results from both the wind tunnel tests and AeroCloud's simulations. The bar diagram below visually illustrate the match between experimental and CFD results, in the different highlighted configurations of the DrivAer model.

_Comparison of drag coefficients for the DrivAer model:  Wind Tunnel Experiments vs. AeroCloud Pro CFD Simulations._
 
 The data in the bar diagram demonstrate that the AeroCloud CFD simulations closely match the experimental results in every case, with only minor deviations in percentage: relative differences within +- 4 %. This exceptional level of agreement between the real-world tests and AeroCloud's predictions is a testament to the tool's accuracy and reliability.
 
### Exploring the High-Performance Vehicle Validation Case

In a recent study, a new validation case was conducted for the CFD tool NablaFlow's AeroCloud, which focused on a high-performance enclosed-wheels car based on the DrivAer model [5]. This validation case compares the simulation results of the drag and lift coefficients done in AeroCloud with the results presented in the study by Cranfield University, in which the DrivAer geometry was modified to represent a more realistic high-performance enclosed-wheels car [5]. The results further emphasize the tool's accuracy and capability to handle complex aerodynamic scenarios.

The study demonstrated that the high-performance model produced a higher drag coefficient compared to the baseline model, with an increase of about 0.1, as illustrated in the bar diagram below. This was due to the presence of additional aerodynamic devices mounted on the original baseline model. However, the higher drag also corresponded to greater downforce generation, which is typical in motorsport applications.
Interestingly, as the car model approached the ground, the aerodynamic efficiency increased. The study found that the minimum drag occurred at the highest ride height, while the maximum drag was at the lowest ride height, as shown in the bar diagram. Downforce was also found to be more sensitive to ride height changes, especially for the high-performance model equipped with aerodynamic devices designed to generate downforce and enhance ground effect. Refer to the bar diagram below for a visual representation of these findings.

![Picture 5.png](https://nablaflow-cms-uploads-production.s3.eu-west-1.amazonaws.com/Picture_5_738988ca63.png)
_Comparison of drag coefficients for the baseline and the High-Performance model for different elevation levels:  Wind Tunnel Experiments vs. AeroCloud Pro CFD Simulations for the DrivAer model._

One key finding of the study was the impact of various aerodynamic devices on the baseline model. The front splitter was found to create a stagnation point above the plate, resulting in increased pressure on its upper surface and generating downforce. The rear spoiler, on the other hand, led to a larger wake and higher drag due to its effect on the base region. The underbody diffuser was found to increase both drag and downforce, while also causing a strong asymmetry in the wake.

_Comparison of drag coefficients for the baseline and the baseline with added parts:  Wind Tunnel Experiments vs. AeroCloud Pro CFD Simulations for the DrivAer model_

These insights not only provide a better understanding of how aerodynamic devices and solutions influence high-performance vehicles but also highlight the importance of considering ground effect and ride height changes when optimizing vehicle aerodynamics. By utilizing the data obtained from this study, engineers can make more informed decisions about the design of high-performance cars and improve their overall performance on the track.

### Key Findings

A closer look at the results reveals the most important effects of different car parts and types on the flow:
1. Rear Ends: The Estateback model, characterized by a large slant angle and no boat tailing, exhibited the highest drag due to a larger wake and separation at the sharp trailing edge. The Notchback model showed a slight increase in drag compared to the Fastback, owing to the early separation on the rear windscreen and the resulting longer wake.
2. Underbodies: Models with smooth underbodies produced lower drag, highlighting the significance of underbody paneling in reducing aerodynamic losses.
3. Cooling Systems: The highest drag among all configurations was observed in models with open front grilles. The cooling air flow caused energy loss due to turbulence, friction, and pressure loss across heat exchangers.

Furthermore, the high-performance vehicle validation case demonstrated the effect of various aerodynamic devices on the drag coefficient and downforce generation. The study also highlighted the importance of considering ground effect and ride height changes when optimizing vehicle aerodynamics, which can contribute to better overall performance on the track.
By consistently delivering accurate drag coefficients for different car configurations, AeroCloud proves to be a powerful and dependable tool that can significantly aid in the design and optimization of efficient and eco-friendly vehicles. The consistency between the wind tunnel tests and AeroCloud's simulations showcases the immense value of this cutting-edge technology for the automotive industry.

### The Verdict: AeroCloud Delivers Remarkable Accuracy

After comparing the drag coefficients calculated by AeroCloud with those obtained from real-world experiments for both the DrivAer model and the high-performance vehicle validation case presented in [5] by the Cranfield University, we found that the tool's results were in excellent agreement with the experimental data. This indicates that AeroCloud is highly accurate in predicting the aerodynamic behavior of various car configurations, making it a reliable and powerful tool for designing and optimizing vehicles.

### AeroCloud's Impact on the Automotive Industry

As a testament to the effectiveness of AeroCloud, our tool has been used in the development of the world's fastest electric cars, such as Automobili Estrema's Fulminea.

How can we be sure that AeroCloud is up to the of understanding and optimizing the aerodynamics? The answer lies in validation. 

AeroCloud validated with DrivAer model

**For decades, the world has worked towards a goal of increasing global sustainability. With growing pressures on the environment, cities, product industry and climate conditions, we have to work harder and nimbler with new ideas to foster sustainable innovation.**
 
When we talk about the future, we should not focus only on predictions but also on solution-oriented scenarios. We believe in sustainability as our core value to help ensure a better future for all of us.
At NablaFlow, we believe that sustainability is not just about natural resources and pollution. It's also about the conditions we create in developing our habitats and how we handle product creation in all industries.

## Simulation driven design improves the product life cycle
In order to ensure a more sustainable future, we can, for example, take into account issues like energy usage and resources and time spent on product processing. When making future-focused decisions it might be useful to take the time to consider impact of our activities on the planet and the finite resources available.

![Picture 1.svg](https://nablaflow-cms-uploads-production.s3.eu-west-1.amazonaws.com/Picture_1_312128d82d.svg)
 
More and more great-performing organizations use [aerodynamic simulations](https://nablaflow.io/en/aerocloud) within their different design phases. According to one of the [Aberdeen Group’s reports](https://www.aberdeen.com/), the design engineers can create 27% fewer prototypes since they adopted CFD simulation tools within their workflow. The direct impact on their overall time spent on the design workflow decreased by 29%.  Besides the time spent on design phase, the engineers relying on simulations during the different design phases, have noticed an increase in their product quality, meeting the deadlines easier, cutting cost and improve their revenue.

## Urban climate CFD modelling helps generate more climate friendly cities and habitats
High performant computing [CFD innovative](https://nablaflow.io/en/archiwind) solutions can help cutting down on the resources spent on creating wind and thermal-proofed cities, while also generating more value and faster. Not only do we now have the technology to help us build a better future for the next generation, but we can also benefit from its cost-effectiveness and fast implementation. To help improve life standards for all. According to the researcher [Parham A. Mirzaei](https://www.sciencedirect.com/science/article/abs/pii/S2210670721001293), “urban climate is recognized as one of these challenges, impacting on the daily life, health, comfort, economic and social behavior of city inhabitants”.

![Picture 2.svg](https://nablaflow-cms-uploads-production.s3.eu-west-1.amazonaws.com/Picture_2_0734b7c298.svg)
 
The urban climate can be influenced by many factors and can be unsteady, but each city or area has its own pattern. Some places can be predominantly windy, but other cities can be overheated. Urban climate CFD models and simulations can help find design and planning solutions for improvement. CFD can resolve the transfer of heat and mass and their interaction with individual obstacles such as buildings and other landscape design elements.

## Commitment and alignment to the UN Sustainable Development Goals
 
![Picture 3.png](https://nablaflow-cms-uploads-production.s3.eu-west-1.amazonaws.com/Picture_3_21229e8e02.png)
 
As the world is fast changing, it is our responsibility to ensure that it changes in the direction of a more sustainable future, and we believe that simulation technology can help us on the way there. Our commitment has been also inspired by the [UN Sustainable Development Goals](https://sdgs.un.org/goals). Our mission aligns with several of them, including:
- [SDG 9](https://sdgs.un.org/goals/goal9) Build resilient infrastructure, promote inclusive and sustainable industrialization and foster innovation;
- [SDG 11](https://sdgs.un.org/goals/goal11) Make cities and human settlements inclusive, safe, resilient and sustainable;
- [SDG 12](https://sdgs.un.org/goals/goal12) Ensure sustainable consumption and production patterns;
- [SDG 17](https://sdgs.un.org/goals/goal17) Strengthen the means of implementation and revitalize the Global Partnership for Sustainable Development.

To ensure a more sustainable future, we can help enhance inclusive and sustainable urbanization, sustainable human settlement planning and management, and help improve the production pattern in many countries by building strong international partnerships and democratize the access to CFD simulations.
 
Here is how we envision the future of CFD simulations and its support for the energy transition:
- Reduce operations’ costs and waste;
- Stimulate the industrial degrowth
- Access faster, more consistent and reliable results for prototypes and solutions;
- Reduce emissions, time to market and time to scale;
- Generate more energy efficient products;
- Help build more climate friendly cities.

It is important for us to do this work because we want to help future generations have a place to live that is healthy and sustainable. We believe that we all have the responsibility to take action now so that future generations can enjoy a healthy planet and have access to clean air and water for years to come.
We strongly believe that the future can be bright and sustainable. That's why we are dedicated to helping industries build a more sustainable future for their organizations and the planet.

**Trondheim, one of Norway’s windiest municipalities, recently enlisted the help of NablaFlow to investigate the possibility of extending the use of Granåsen Ski Centre to also include a big jump to facilitate freestyle skiing and snowboarding Big Air events.**

Located in Trondheim, Granåsen Ski Centre is known for hosting World Cup and Continental Cup ski jumping competitions as well as world-class biathlon and cross-country skiing competitions. The Centre has one normal-sized hill (K-90) and one large hill (K-124). The proposed plan would require the removal of parts of the existing forest and reshaping of the terrain to form the big jump and necessary landing and entry area.
However, the modification to the surrounding area of the ski jumping facilities could  affect the wind conditions, potentially worsening the conditions for the jumpers. Therefore, Trondheim kommune wanted to be informed on the likelihood and extent of the possible implications.

![Streamlines coming from the simulation run with ArchiWind, crossing the Ski Centre Area](https://nablaflow-cms-uploads-production.s3.eu-west-1.amazonaws.com/8_330e75c7e8.png)
_Streamlines coming from the simulation run with ArchiWind, crossing the Ski Centre Area_

NablaFlow conducted a CFD (Computational Fluid Dynamics) investigation of the impact of the proposed modification to the forest and terrain on the wind velocities and turbulence at the ski jumping facility. The firm used their ArchiWind tool and developed and applied some project-specific extensions to their fully automated platform to include the modeling of the effect of the forest on the wind conditions.
Simulation results showed that the big air jump would affect the local wind conditions around the big air jump but not notably in the ski jumping arena. The information obtained from the simulations allowed Trondheim kommune to make an informed decision on implementing the proposed plan. It also ensured satisfactory similar wind conditions at the ski jumping arena after implementing the modification to the forest and terrain neighboring the ski jump arena compared to before the project.

Investigating the Possibility of a Big Jump for Freestyle 

**Recently, DARK Architects and MaPlan announced plans to begin the process of regulating Arne Rettedals gate 12, located in Stavanger, on behalf of the local developers. The proposed development includes the construction of two additional floors for office use and an update to the current regulation plan, which dates back to 1972 and lacks specific provisions.**

As with any new development, it’s important to consider the potential impact on the surrounding area and the people who will be using it. One important factor to consider is the urban wind situation. Wind patterns within cities can be affected by the way buildings are arranged and the materials they are made of. This can have a significant impact on the comfort of pedestrians and the overall user experience of the area. By conducting a wind study, we can better understand how the proposed development will affect the urban wind situation.

![City view of the building model in the surrounding area with streamlines](https://nablaflow-cms-uploads-production.s3.eu-west-1.amazonaws.com/6_eb645c1e06.png)
_City view of the building model in the surrounding area with streamlines_

At Nablaflow, we specialize in wind studies and have conducted a wind study over the area including the proposed new building model as well as the nearby high-rise currently under construction. Will a new restructuring of the building have a positive impact on the urban wind situation? New structures can potentially reduce the wind speeds at pedestrian level, aspect that needs to be considered when planning on changing the height or the exposed surface of buildings.

Assessing the Impact of the restructured design in Stavanger

When designing new waterfront structures, it’s important to consider the impact of wind on pedestrian comfort. That’s why Stafr, the project managers for the new project Pynteneset, enlisted the help of NablaFlow to conduct a wind study on their new residential area in Stavanger.

![Untitled design.png](https://nablaflow-cms-uploads-production.s3.eu-west-1.amazonaws.com/Untitled_design_c761b32d43.png)
_NablaFlow’s copyright: Another rendered view of the 3D model coming from the simulation run on Archiwind, and elaborated by the team_

Nablaflow used their software-as-a-service tool, Archiwind, to run a complete wind study on the area. Archiwind is an almost fully automated, versatile, and easy-to-use tool that allows for cost-cutting in wind studies like this one.
The report generated from the tool also provides the necessary documentation required by the municipality in addition to the powerful results page with great visualisations.

The results of the study will be used to inform the designers of the new residential area in its development stage. Further wind studies may be conducted in the future before new construction stages begin.

Overall, the wind study conducted by Nablaflow will ensure that the new waterfront structures in Stavanger are designed with pedestrian comfort in mind. The use of Archiwind allows for efficient and accurate analysis of the wind conditions in the area,
making it an invaluable tool in projects like this one.

_NablaFlow’s copyright: The simulated area uploaded on Archiwind_

Når det prosjekteres nye utbyggingsprosjekter, er det viktig å ta hensyn til hvorledes
vind påvirker komforten til brukere av området. Dette er grunnen til at Stafr, utbyggers
prosjektledere for Pynteneset prosjektet, benyttet NablaFlow for å utføre en vindanalyse for den nye boligutbyggingen sin på Engøy i Stavanger.

NablaFlow benyttet programvaren sin Archiwind for å gjøre en komplett vindanalyse av utbyggingsområdet, med hensyn på omkringliggende arealer og bebyggelse. Archiwind er et nesten fullautomatisert, fleksibelt og brukervennlig verktøy som bidrar til kostnadsreduksjon i forbindelse med utarbeidelsen av slike analyser.
Rapporten som genereres gir det nødvendige underlaget som kreves fra plan og bygg,
samtidig som resultatsiden er et visuelt sterkt og lettfattelig verktøy for alle prosjekterende involvert i prosjektet.

Resultatene fra en slik analyse bidrar til å optimalisere prosjektet med tanke på komforten for fremtidige brukere som enten bor i prosjektet eller besøker dette vakre kystområdet. 

Da dette er en trinnvis utbygging, vil det også gjennomføres analyser for de resterende trinnene etter hvert som de nærmer seg utførelse. Takket være Archiwind er det nå både raskt og rimelig å utføre slike analyser, noe som igjen resulterer i mer bærekraftig utvikling av våre byer og nabolag.

Archiwind as a tool for urban design

**Manufacturers of electrical supercars have a vested interest in the future: a greener and more sustainable one. In addition to the challenge for supercars that can accelerate more quickly, manufacturers are working toward a more environmentally friendly future.**

Electric cars have now made a serious entry into the world of super sports. In the past several years, a lot of automakers have established electric car brands that compete with one another to see which one can produce the world’s fastest electric car. 

As Forbes contributor, [James Morris, stated](https://www.forbes.com/sites/jamesmorris/2022/04/23/is-the-future-of-supercars-electric/?sh=4913527441c6), the "electric supercars are already the fastest-accelerating production vehicles in the world, and it’s likely that they will dominate both top speeds and track lap times in the future. The age of the internal combustion supercar is drawing to a close, and the electric supercar era is now emerging." 

## Automobili Estrema is aiming for the speediest super car trophy
![Automobili Estrema’s copyright: Fulminea, the new Italian supercar model ](https://nablaflow-cms-uploads-production.s3.eu-west-1.amazonaws.com/02_ad54f6ce58.jpg)
_Automobili Estrema’s copyright: Fulminea, the new Italian supercar model_

A number of brands like Lamborghini, Porsche, Ferrari, Tesla, Rimac, Bugatti, Volkswagen, and others have launched vehicles that could go head-to-head with exclusive traditional sports cars. Some of them are working on new improved models able to win the speediest electric supercar contest.  

[Automobili Estrema](https://fulminea.com/), another of a new breed of supercar manufacturers, is aiming to take on its competitors. The start-up company based in Modena, Italy, is developing an electric supercar that will rival the latest offerings from Rimac C-2, Lotus Evil, Pininfarina Battista, Lamborghini Terzo Millennio. Their vision is to become the next Italian automobile sports car brand. They created their first model starting from scratch, called Fulminea, which means lightning fast in Italian. The supercar will have over 2,000 bhp and a mind-blowing 200mph sprint of under 10 seconds.  

To achieve its double goals of faster and greener acceleration, Automobili Estrema will use [AeroCloud's CFD simulations](https://nablaflow.io/en/aerocloud) and our team of experts in aerodynamics. As we speak, the CFD tool is being implemented into their design process toward Nürburgring 1927 GmbH & Co. KG's record attempt next summer. 

## Go faster and consume less with the help of CFD simulations
![NablaFlow’s copyright: Fulminea’s CFD simulation -  recirculation around the model ](https://nablaflow-cms-uploads-production.s3.eu-west-1.amazonaws.com/04_0308cc2bca.jpg)
_NablaFlow’s copyright: Fulminea’s CFD simulation - recirculation around the model_

Aerodynamics are critical for performance in racing. With the help of computational fluid dynamics simulations, we will make the race supercar more efficient in terms of power consumption, and more performing. Indeed, producing less aerodynamic resistance allows the car to go faster without consuming as much power. Fulminea will also develop downforce, that will make the car maintain its speed through turns without having to decelerate too much.   

The more aerodynamic the supercar is, the less energy it requires to run at the same speed as a less aerodynamic car. A car that uses less energy requires smaller batteries, which means it can be lighter, which means it will need even smaller batteries. When it comes to breaking the Nurburgring's lap record, whoever is able to build the car with the smallest resistance and weight, and with the best performance in turns has the best chances to succeed. 

## We want to help push the technology forward
![Automobili Estrema’s copyright: Roberto Olivo, the COO and Gianfranco Pizzuto, the CEO  ](https://nablaflow-cms-uploads-production.s3.eu-west-1.amazonaws.com/03_cc87d12c27.jpg)
_Automobili Estrema’s copyright: Roberto Olivo, the COO and Gianfranco Pizzuto, the CEO_

Electric vehicles are the future because they are better for the environment offering a greener solution to the internal combustion, and as a result, electric hypercars are the next step to push the technology forward. Sure, the technology is not perfect, but it will be. And the truth is, we can’t escape that fact. Not in any meaningful sense. Because the future is already here. 

A world with more electric cars and less internal combustion engines aligns with the United Nations directives for a cleaner and more affordable energy. We couldn’t let this opportunity pass by. Helping Automobili Estrema achieving their goals reflects the values we believe in: better performance, and greener future.
