INDYCAR DW12 SCALE MODEL
ARC is pleased to announce the building of an Indycar DW12 scale model for public wind tunnel testing. The model will feature the 2015 body kits and standard bodywork.
This scale model will be ready for 2014/2015 off season testing. Be sure to check this newsletter next month for updates on the build progress.
CFD OF INDYCAR DW12 AVAILABLE
ARC has a complete model ready for running CFD on the current DW12. This model was created from cad & scan data, it features:
- Fully Deformed Tires
- Scanned Helmet & Adjustable Driver Position
- Detailed Engine, Transmission and Exhaust
- Mass Flow rates for Air Intake & Exhaust Outlet
- Adjustable Suspension and Car Geometry
- Fuel Buckeye for lh or rh fitting
- Thermal Exhaust Exit Temperature
- Sliding mesh for Overtaking Analysis and Wheel Rotation
- Many other features for Increased Accuracy
The CFD model is the ideal testing grounds for setup analysis, brake cooling, powertrain cooling and a more detailed graphical understanding of flow around the car.
Using ELEMENTS CFD, the Indycar model can be run in either steady state or transient analysis. The coding in ELEMENTS is optimized to allow for transient runs to be done much more efficiently than other platforms.
ARC looks forward to ensuring your success

What is the difference between steady state and transient CFD runs?
Computational Fluid Dynamics is a simulation technique for predicting flow around and through objects. It is used extensively in the automotive industry for:
- Aerodynamics (drag and lift prediction)
- Powertrain Cooling
- Cabin Cooling
- Brake Cooling
- Soiling Prediction
- Wind Noise
- Crosswind Stability
Most commercial codes have until recently used a simplified approach called Reynolds Averaged Navier Stokes because of how difficult it is to solve these problems. This produces a steady state flow field that loses a lot of the finer details of the flow.
More recently transient techniques such as Detached Eddy Simulation (DES) have become more common as they better capture the turbulent flows common around cars and trucks. They are more accurate but typically take up to 5-10 times longer to compute.
ELEMENTS Analysis is a new CFD code that only takes twice as long to compute transient simulations. This makes it 3-5 times faster than the competition and gives you maximum accuracy in shorter time. Learn more about ELEMENTS at http://elements.streamline-cae.com.
