Instead of modeling, how about measuring? Mount this little sucker just behind the front mesh or just under the car at various locations and see what the airspeed velocity really is. If you really wanted to you could run a section of brake duct and cut it off before it gets to the brake and afix this to a piece of hardpipe attached at the end of the brake duct and measure the velocity where you most care about. It goes up to 56 m/s (or about 125 mph), hooks up to your i-phone, it is cheap, and gives you real data without the modeling error. Doesn't accomplish the modeling of the whole car but would more than suffice for detecting high pressure areas where you could put cooling ducts.
come on calvin you are engineer that would be to logical
Willy, I think your design would be great for the track. But this type of splitter would be more practical for the street. Anyone know this car or where the splitter came from?
I know that car very well and it is a beautiful splitter for the street but not very effective
i will talk to him about making some more
Important question how many people would be interested and how much would you pay for it
