Hi guys,
I'm doing a validation of the NACA 2412 profile at Re=2200000. I used a C-grid with 20 chords in the front and 50 on the back. I did a first structured mesh with 60000 and 180000 knots using an adapted bias in order to have y_plus<1. However, the results regarding Cl and Cd are so different when using K-q SST and SST transitional. 60000 nodes K-W: Cl=0.21314 and Cd=0.009669 60000 nodes SST transitional: Cl=0.23374 and Cd=0.0047277 180000 nodes K-w: Cl=0.21335 and Cd=0.0096094 180000 nodes SST transitional: Cl=0.23549 and Cd=0.0046394 The results of K-w SST are much more similar to the experimental ones. Could there be any problem regarding the mesh, geometry or the boundary condition? |
