about the SCCR aero study at this link ..

Post

Here's the link to the excellent, detailed study of this car
http://www.f1technical.net/articles/71

For those aero experts out there please help me with this ..

During all the flow line studies, and most pressure studies everything looks great. However in the diffuser static pressure study (see below) there looks to be an area of turbulence or static flow right in the middle of the diffuser. It doesn't show up on any other illistrations though. Is this just an anomaly? Should someone be concerned about this?

The diffuser area on this car is pretty aggessive when you consider that the sides are expanding at a large rate, so some problems in this area would make sense. What do you guys think?

The pic you linked to the velocity and the high speed area in the middle of the diffuser can be explained by this pic :

as you see at a given point there are path lines crossing the diffuser transversally.

BTW, there must be a problem with the website hosting your avatar, it asks me a password :?:

Outside of clicking the link up there how do I get to these articles? When I click on the articles link on the tool bar I can only select the and not actually see catagories.

So what is this indicating, and is it a bad thing or a good thing? I'm thinking it's flow separation creating turbulence, correct?

Thanks

Oh thanks for the avitar thing too. I just threw it up there while on another site and yes it was apparantly password protected.
PS: this article is located in the CFD section of the forum, as a link there. Follow the crumbread menu bar at the top.
