Hello,

Have you heard of SpaceClaim? It is a solid modeler that costs much less than SolidWorks and it very intuitive to use -- a lot like SketchUp:

I don't think it would be a problem. You suggest that some significant volume of air is entering the well from somewhere and needs an escape. I don't think that's the case.

Wow. That's pretty darn conclusive. It would be tuft to beat that mod for turbulence reduction.

Thanks for that. Very professional looking. My wheels are turning to figure out a set for my van.

Nice.

Very nice. I was surprised to see the improvement even above the wheel well. That is quite the difference.

Yes, but doesn't flow seperation happen earlier/easier (you know what I mean) at higher speeds?

perhaps it would be interesting to use the same setup to test vortex generators behind an open front wheel well.... front wheel skirts are not really an option for everyone,

but perhaps some vortex geneators just aft of the wheel could improve the situation over stock.
some people claim they should be placed in front of a wheelwell so that might be tested as well.

the full wheelwell cover will likely be superior, but it would be interesing to see where vortex generators are positioned betwee these two extremes
