The DrivAer experiment is a validation exercise for CFD solutions of passenger cars. The picture shows the flow velocity near the surface of the DrivAer model with mirrors and detailed under body. The problem was analyzed in Stallion 3D using 1.7 million cell and the RANS/k-epsilon solver. The solution was unsteady with an average drag coefficient of about 0.29.
The results from Stallion 3D 5.0 RANS solver (CL = 0.41, CD = 0.25 & CM = -0.0387 ) were compared to the findings of NASA Technical Memorandum 4117,Transonic Aerodynamic Characteristics of a Proposed Assured Crew Return Capability (ACRC) Lifting-Body Configuration by George M. Ware. From the graphs, the corresponding experimental results were (CL = 0.48, CD = 0.24 & CM = -0.042). The geometry was obtained from NASA OpenVSP. The flow parameters for this case are M = 1.2 with an angle of attack of 12 degrees. This simulation used about 480,000 cells and ran for 3 hours on a 2 GHz laptop computer.
Stallion 3D used the August, 2016 implementation of its RANS/k-epsilon solver for this analysis the ONERA M-6 wing. The CAD model was obtained from NASA OpenVSP hangar. The simulation was setup for the well know case of M=0.84 and an angle of attack of 3.06 degrees. This case used a grid of 447,640 cells and ran for 6 hours on a 2 GHz laptop computer with 4 cores. The picture shows the pressure on the wing along with comparisons of the computed CP versus the experimental data at 2 stations along the wing. Since no experimental values of CL and CD were found, the lift and drag coefficients were compared to results from NASA's CFL3D (Spalart-Allmaras model).
