Accelerate aerodynamics innovation using digital wind tunnels
Accelerate aerodynamics innovation using digital wind tunnels

Stricter emission limits and new test procedures put the automotive and transportation industry under a lot of pressure. The Worldwide harmonized Light vehicle Test Procedure (WLTP) introduces a new driving cycle (WLTC), resulting in a higher average and maximum velocity during testing. For this reason, the importance of aerodynamics is increased. Simulation provides a way to improve aerodynamics earlier in the design cycle allowing vehicle manufacturers to enhance aerodynamic performance before the first physical prototype. But to be successful, the digital wind tunnel results need to be validated.

In this webinar, our experts, with the co-operation of Chalmers University and Volvo cars, will explore the correlation between test and the digital wind tunnel for a slotted wall wind tunnel. In addition to comparing the physical and digital wind tunnel, the results are also compared to an open road CFD setup to see the impact of the wind tunnel. Finally, our experts will detail a fast method to get even higher throughput on the simulation, allowing the possibility for completing hundreds of design studies in a single week.

What will you learn in this webinar?

  • How to reduce costs by designing with digital wind tunnel
  • What are the important factors for correlating to a physical wind tunnel
  • Understand how the wind tunnel impacts vehicle aerodynamics compared to open road
  • Get familiar with methods to enable looking at hundreds of variants within a week, thus allowing reduced design time
