Hi everyone,
for my thesis I am trying to simulate a set of blade in a wind tunnel (precisely just one blade with periodic condition).
I have already create my own mesh with PointWise but I am struggling with OpenFoam. I was told to start with a simpleFoam tutorial, one which uses a two equations model, but I am not sure that is the right choice.
I have an high Reynolds number (around 10^5), with an isoentropic Mach number of 0.2 downstream of the blade. At the inlet I have a uniform velocity of 21 m/s, at the outlet a uniform pressure. There is a simmetry condition on a plane located at the midspan so the mesh is splitted in two half. The two lateral surfaces have periodic (cyclic in OpenFoam, right?) condition.
From which tutorial should I start? Can you help me in particular with the boundary conditions (epsilon and k)?

Thanks in advance!
