Problem with k Boundary Conditions in k-omega SST model

mech_engg_swag · March 9, 2016, 15:11

I am trying to use the k-omega SST model to simulate incompressible flows over airfoils from Re=200000 to 500000 with freestream Turbulence Intensity 0.1%. I have yet to decide the chord length, freestream velocity, and freestream TKE. The shape of my mesh is as given in the image.
Is it possible to use k-omega SST for this scenario? If it is, then how do I go about this problem?

Thanks in advance.

I am mainly facing difficulty in deciding the chord length, wingspan and computational domain length. Once I have the chord length, I can get the freestream velocity, and hence the freestream TKE. I am referring the paper on this link : https://drive.google.com/open?id=0B3...GEybXNEMXVmY3c. I am using equations (A11) and (A12) to get the BC's.
