Been a while since being in here. Bought a 2016 ND Miata though so the development begins. Since I am an aerodynamicist, aero work is of course going to be first.
Overall Cp plot on the car. Cp is better metric to look at in my opinion than just pressure. Cp of 0 = freestreem pressure. Cp>1 = high pressure zone. Cp<1 = low pressure zone.
Cp plot on miata with streamlines of the wall shear vectors (aka how the flow regime is acting on the surface)
Underbody shot of diffuser development. Yes this has a simplified underbody as I will be doing a completely flat floor.
Vortex forming at one of the strakes on the diffuser. This helps keep flow attached at higher angles of attack on diffusers
Another vortex on the strake on the diffuser. Notice the low pressure in the core of the vortex.
Streamlines off the rear of the miata
Oh and here is the actual car
