Using ANSYS Fluent, we are trying to calculate the output power of a wind turbine blade (NREL PHASE VI) from which the experimental results are also available. We know number of blades (2), rotor diameter (5m), RPM (72) and pitch angle (3).

We have some questions:

1- There is just the pitch angle of the wind turbine blade is given and I could not find the angle of attack. Do people use just the pitch angle and don't use angle of attack to verify their simulation?

2- How do we calculate power output from Torque?
We obtained a Torque value after a simulation. We know that Power= Torque x Angular Velocity. Do we calculate the angular velocity from the given RPM? Is this RPM same for every wind speed (I guess not)?

3- To calculate power output, do we just multiple blade number with our result from the anlysis of a blade?

Thank you,
