PowerFLOW 5.4 - Simulating Rotating Tires

Expressions of driver individuality happen where the rubber meets the road: literally. Tire tread patterns and unique wheel designs offer a subtle statement that can make a big difference in vehicle aerodynamics.

How big is that difference? Up to 20-30% of a vehicle’s aerodynamic drag can be attributed to the wheels. Join the Exa webinar, Simulating Rotating Tires with PowerFLOW 5.4 on Thursday, June 15 at 10 AM EST to learn how simulation-driven design in Exa evaluates the real-world effects of rotating tire and wheel geometry on a design’s performance to help our customers overcome these common aerodynamic challenges:

  • Tires and wheels create a complex flow field that can create unexpected sources of drag;
  • They come in myriad different patterns, resulting in a huge number of combinations to test; and
  •  Under WLTP – a new, worldwide regulation that raises standards for predicting on-road fuel economy to ensure that the sticker’s promise matches the driver’s experience – OEMs will be required to certify all combinations of wheels and tires sold for every vehicle
You’ll learn how Exa customers have realized proven aerodynamic advantages using this new methodology to simulate rotating tires in PowerFLOW 5.4.
