Hello,
I just wanna ask you what's the difference btw 'Pressure Far Field' and 'Velocity Inlet and Pressure Outlet' when setting up the model of 2D airfoil (here, tried NACA 0012). I tried both of them and found the following trends. For the Pressure Far Field set, Cd and Cl have a periodic trend on their graph and it repeated. For the other case, Even though the result of the two dimensionless factors showed a good convergence, the converged values were too far from the experimental ones. So, I am wondering what I should look at when setting up the model for the boundary conditions. |
