Savonius Wind Turbine CFD
 

Hello,

I am simulating a 3 Bladed Savonius (VAWT) wind turbine. I am using Moving Reference frame to rotate the blades. But i want the fluid to drive the blades instead of giving it a fixed rpm. How can i do that?

And again i want to get the values of Normal and Tangential Drag Co-efficient ... Is it possible to get these data from fluent?
