MRF query

I have one basic doubt for rotating flows. let's say I have to doflow analysis of a turbine. I will be having one stationary domain (stator) and one rotating domain(rotor). I am using MRF Suppose my rotor is rotating at 50000 rpm. Then am I required to apply rotation to walls of blade . My doubt is whether blade walls remain stationary or not? Is it stationary wrt rotating region? So, I can do two things. (1) Apply 0 rpm in relative frame. (2) Apply 50000 rpm in absolute frame. Which one is right?
Kindly let me know the answer. |

If you solve rotor region on the rotating frame, then the blade should have velocity relative to that frame. In your case, it is zero.
