Excessive torque (cm) for 2D vawt
 
1 Attachment(s)
Hi,
I am simulating a 2D VAWT using a sliding mesh and I get excessive values of torque (cm). Maybe I am defining wrong the values of area, length and depth in the section "Reference Values". Someone can help me?
The velocity inlet (wind velocity) is 5 m/s, the angular velocity w= 20 rad/s for a TSR=2. I attached a picture with the measures of the Vawt.

Thank you very much.

Hi , why did you take this values for your boundaries? Is there any reference for them?

Thank you
