Geometry: This rear wing is known by many F1 sites, and was produced a whole ago, unfortunately the designer is not known. As far as I can see the airfoil profiles are not of a published design (such as NACA). The original geometry file was very dirty and much cleaning by Keith Young was needed to ensure all surfaces edges were congruent.
From looking at a 2D view of the airfoils on this wing, it was suspect that flow separation would occur from the 2nd element. A picture of the geometry is show both in Rough_Wood's (Keith) post and below in CFX which shows a close up of the fine mesh used for analysis.
Mesh Data: Total number of Tetrahedron elements = 2,151,110
Total number of Faces = 136,696
Flow Conditions: Again, the analysis was of the wing itself and no other body members were included, therefore ignoring any body interactions with the Formula 1 vehicle. The results from analysis can therefore only be used for initial design of the wing system, and all body interactions should be included and analyzed in further design modifications. The initial flow velocity was set at 53.33 m/s (120 mph, 192 KPH). All walls of the fluid domain were set to free slip (so taking in to account ground effect) and a no-slip condition applied to the bodies surface.
Solution: Solution ran to a convergence of e-5, Time run taken = 6 hours, 52 minutes, 4.656 seconds
Results: The first image just shows roughly where the planes that many of the pictures refer to are on the geometry. I think the most obvious signs from these plots is the huge stalling of the 2nd element of the wing. Also large vortices are formed, however I can imagine these would be completely different when the wing is modeled on the car itself as the wheels and body would influence the flow streams
Results write up yet to be completed!!!!! Ran out of time!!!!
Force Data: Downforce = 461.511 N, Drag = 99.1276 N, Pitch = 453.616 Nm
