What is the most efficient airfoil for a horizontal axis wind turbine with rotor diameter 1.6 meter and rated velocity 7 m/s ???

In WECS : Gain values for conversion of PMSM rotor speed(rad/s) to p.u. input to wind turbine and Torque(pu) of WT to input of PMSM-Torque (Nm) ?

I am working on developing a MATLAB Simulink model of Wind turbine with PMSG followed by MPPT Boost converter. I have gone through so many literature and videos but I am not finding clear solution...

I came across oscillations in a pressure profile for a pipeline flow along the axis of a cylinder, how do I prove that these are not numerical err?

In terms of CFD, we often analyze the stability of the error using Von-Neumann analysis, especially for FDM based problems. Should we follow the same approach for a compressible fluid flow using FVM ?
