Hello,

I am currently running a simulation of 3 bladed Savonius Wind Turbine with no blade overlap. My professor asked me to validate my results with a paper of wind tunnel results. In the wind tunnel experiment they have calculated the normal and tangential drag co-efficient and Cp (pressure co-efficient) with respect to blade angle.

But in fluent i'm not finding any way to calculate the co-efficients.

Can anyone tell me how can i get this results?

Thank you for your attention.
