Radially dependent torque coefficient

Wind & Water Rotor Aerodynamics
1

Hello everyone,

I am working with the 15MW IEA RWT wind turbine model and I would like to obtain the torque coefficient for each section of the blade [Cq(r)] (I attach an example from the 5MW model [1]) as a function of pitch and TSR. I found thas this could be done using an app called WT_Perf, which also considered root and tip losses, but it is no longer available. I would like to know if it is possible to obtain these values through the AeroDyn driver or any other method.

Thank you very much!

Best regards,

Dear @Daniel.Lacheta,

AeroDyn does not currently calculate and output the local sectional torque coefficient, C_q(r), but of course, you could calculate it from the local aerodynamic force and radius.
