I was clearing out my computer this evening and came across the computational fluid dynamics simulations from back when I looked wing options for my 996 outlaw project. The idea was to run a larger wing, mounted higher up on the car than the stock one already fitted.
While theory and data from some other cars suggested that doing both would be of benefit, in order to understand and evaluate various options, CFD simulation software was used to show in a time and cost efficient manner just what would be going on. I'm not much one for guessing.

Anyways, here are some of the results for the final wing (size and height). The plots shown are all for a simulation run at a speed of 40 metres per second (so not quite 90 mph).

Scales and other info have been removed, I'm not giving everything away, but what is going on should hopefully be enough for a gratuitous forum post. I assume its not something many people get to see so figured it may be interesting to put a couple of images up.

edit to add: if you want to see the images a little bit bigger you can click through to the hosting page.

i) Velocity vectors and streamlines.



ii) Turbulence dissipation.



iii) Turbulence energy.



iv) Pressure.



v) Total pressure.

Very interesting thanks.
Just wondering how that would have compared to the standard wing fitted, are we talking a slight or significant increase ?? Also any changes at the front, or just the rear wing ??
