I agree with you that the rotating frame is simple method and the simulation time is not too long but in my opinion there is some situation where this approach is not exact.
In the rotating domain a tangential velocity component will appear in every cells . For example: there are a wind turbine which rotates very slowly (RPM:1 rev/s). In the case of application of the rotating frame these tangential components can be seen in every cells of the rotating domain but I think that in the reality these components is much smaller between two blades than along the blades.
In short it is not correct approach that every cells are rotating with the turbine...
What do you think about this?
