If there's any way you could tuft that whole area and get a friend to watch,photograph,or videograph,you could see what's happening there.
If you blended the spat into the rocker panel,as Subaru did with their 1986 XT (Cd 0.29) you could kill any turbulence formation.
*As to the gap behind the rear wheels,yes,seal those areas,after checking out 'diffusers',which you might integrate into your design.These add a premium flow component to the wake area,and later,if you do any boat-tailing,it will pay you extra dividends.  |
Thanks! I'll try to trim the outer edge of the spats to remedy that and see if I can wrangle up a camera rig to do some tuft testing.
I'll set to work researching more about diffusers and rear aerodynamics. Thanks again for your help.
