sergiu tofanel is on a distinguished road
I am running a 2D airfoil simulation of a NACA23012 section using simpleFoam as a solver.

The CL vs alpha seems to be in the ballpark with experimental results, but the drag is way too high. I understand that this is a common problem with turbulence model simulations. Right now I am using the native OpenFOAM SpalartAllmaras turbulence model with the default parameters.

After browsing through several posts on the subject, I am led to believe that the adjustments to the drag solution can be made through the fvScheme and fvSolution files. However, I have no idea how to tweak them. Is there an online tutorial anywhere that can point me to a solution? If not, what is the best way to proceed in this situation?
