I did not know where else to post this, all about flow though.

Lots of interesting diagrams here:

Large eddy simulation of flow structures and pollutant dispersion in the near-wake region of the studied ground vehicle for different driving conditions

I've not had much luck in blowing them up however.

More interesting stuff.

I've been using the GOOGLE image search term "ground effect flow pattern automobile".

I wanted to mention that the upper set of images are 2-D flow studies and lack the longitudinal vortices which are depicted in the bottom 3-D flow study representation
The center table is from Buchheim's measurements of the Schl'o'r car,circa 1938, put together by Prandtl,Rumpler,and Schl'o'r,and I think it's A.V.A. G'o'ttingen,not D.L.R..
