Saturn SL airflow study
Just a little research here.
I made a quick and dirty profile of an Saturn SL in CAD (it is accurate as far as HxWxD) and ran an airflow analysis with some interesting results. There are 3 pics; 1 of the airflow over a stock car, 1 with the addition of a 6” “spoiler” on the trunk set at roughly 5deg down from horizontal (basically following the angle of the trunk lid and 1 with the wing and a simple rear pan (a basic diffuser).
You can clearly see a turbulent area behind the car stock.
The rear spoiler seems to clean it up considerably
The addition of the diffuser seems to refine the airflow a bit more. The diffuser could stand some more optimizing, for sure, but it does seem to work.
I was wondering if anyone has tried these mods and what their results were?
Any thoughts?
Like I said, just kinda playing around and thinking. I know the model is a bit crude (making a 100% accurate model would take a TON of time) but the results were interesting to me none the less.
