Aerodynamics in passenger car

Project Support
15

Hi everyone,

I can not keep up with the topic, but I will point out some issues I noticed.

  • Force and moments & Force and moment coefficients settings
    • Probably the drag direction should be [ dx, dy, dz ] = [ 0, -1, 0 ]
    • Probably the Pitch axis should be [ x, y, z ] = [ -1, 0, 0 ]
    • Put the Center of rotation at the center of the car wheel base
    • Reference: Newbie. Forces and moments Help - #5 by yosukegb4
      • Notice: The values depend on your coordinate system and your car demensions
  • Mesh
    • I think it is better to
      • insert boudary layers on the car surfaces and the floor
      • make mesh smaller around the car
  • Lift
    • Generally, a passenger car sometimes lifts without aero-devices for the downforce

I am sorry if you have already corrected them.

Regards,
Yosuke
