Is it possible to do a CFD simulation of a rotating blade?

I too have the same doubt Mr Diego Fung. I was trying to do a HVLS blade analysis with blades rotating, like your project. But when I searched for tutorials, I found that all the rotating parts need to be constrained so that they become NON-ROTARY components. So till now I know that flow analysis is done in SOLIDWORKS with fixed components and not rotating components. If you have found a solution or a method, it would be helpful for me too.

It is possible by defining rotating region. The following article will give you more insight.

Understanding Rotating Regions in SOLIDWORKS Flow Simulation

Hi Diego,

If you want to see how a wind turbine behaves when the blades are put through different angles of attach you would probably want to employ both a rotating region to represent the spinning of the turbine around the hub along with a parametric study designed to change the angle of attack of the blades.  This video on Flow Simulation (GoEngineer - Flow Simulation Webinar) goes through various topics relevant to what you will be doing here (rotating regions, wind force on blades) but starting at 27:11 it shows the setup of a parametric study which can be the trickiest part of the setup.

You could do what's known as a "frozen rotor" method. The blade will not be moving, but the fluid will be in a rotating coordinate system relative to the blade. So you could get some idea of your blade performance, but obviously it will not be a complete model.
