Hello everyone ,
I am doing my masters thesis on Vertical Axis wind turbine. I have few doubts regarding the simulation
1) My domain is circular. Should I give velocity as magnitude with direction or magnitude with normal to boundary. How does any of them affect the result.
2) I did a trail using velocity with magnitude and normal to boundary but my coefficient of lift Vs AOA doesn’t show dynamic stall occurrence.
How to solve the issue?IMG_3944.jpg
Attached is the file of Cl Vs Azimuth for a NACA0015 profile .
