Is there any relation between blade pitch angle(Angle of attack) and moment in aerofoil?

08 August 2018 0 6K Report

I am doing a CFD analysis of commercial HVLS fans, for various angle of attack i'm getting different torque values. i understand that lift and drag values changes so there is change in torque as well as power fluctuation. but i wanted to know is there any prominent relationship between moment produced by the fan and angle of attack.
