I apologise if my frankness offends you but I tend to get straight to the point :) By the way, I am not angry. Yes, turbulence models are based on theoretical, empirical and even guessed models....

If they are always wrong then why do people buy them? Used properly it is accurate for many cases. The issue is almost certainly a problem in the way the simulation was set up, not the...

Why not model this using the rotating frames of reference? Then you can do a model with the difficulty of a steady state simulation, but include the effects of blade rotation. Much more accurate and...

If this is modelling the blade when stationary then apply a tangential velocity equal to the velocity at your boundary.
