Hello,
How would setting the values for k and the turbulence length scale for the SST turbulence model effect the convergence of a problem ? As I understand the length scale is used to calculate epsilon at the inlet. However if the problem to be solved is a flow over a wing , and the wing is far several chord lengths away from the inlet, I find in contour plots that the kinetic turbulent energy decreases rapidly after the inlet. So what difference does it actually make if I set the turbulence length scale to be the thickness of the wing or the thickness of the boundary layer ?
Thanks
