I am going to 3D flow analysis on 8 bladed aircraft propeller. I came to know that there two ways to do it in fluent.
Multiple Rotating Reference frame (MRF)
This is done by creating three domains.
1 stationary, in front of the propeller
2. rotating, containing the blades,
3.stationary behind the propeller
Single Rotating Reference Frame (SRF)
Propeller is stationary and the flow rotates around it (domain is rotating)
I would like to know which method is correct method and which method is easy to carry out CFD analysis.
