I am currently working on analyzing a radial blower using Fluent. The way I have understood it, is that it can be done in two ways:
1. Imparting the blades a rotational speed and keeping the rest of the fluid zone stationary.
2. Creating a rotating fluid zone around the impeller blades and keep the blades stationary with respect to this region.
I am trying to find out what is the difference between these two approaches with respect to convergence, better correlation with practical results, computational time.
Can someone help me out?
