​Research Motivating Problem:
Aerodynamics plays an important role in road vehicle design since it offers a possibility of getting a reduction in fuel consumption and emission levels. One of the important areas is the wheel-houses, that can be responsible for up to 25-30% of total aerodynamic resistance of a vehicle.

Research question(s):

  • How does one measure ventilation resistance moment in wind tunnel and in CFD?
  • What are the design parameters that affect ventilation resistance?


  • Methods to measure and decrease ventilation resistance moment without affecting aerodynamic drag force of the vehicle.
