Hi everyone;

I'm doing 2D transient CFD analysis of a vertical axis wind turbine. I found the time dependent power output of the turbine but, i'm not sure if the results are correct. Should be the graph oscilating smoothly like sinus graph or there should be some distubances because of the vortex effects?

I found a smooth graph for symmetric airfoil and disturbed graph for cambered airfoil...

Waiting for your comments...
