I have done the analysis for "two stage Savonius rotor with straight 2 blades" with different overlap ratios ranging from 0.1 to 0.3.
for the overlap ratio of 0.15, the net moment I got in Z-direction is 0.0621, similarly I am getting the moment in X, and Y directions also.
Along X-direction---- ( -0.02088) why negative here?
In Y-direction (0.03456).
There is no much decrease in the moment value in other directions compared to Z-direction. Why?
Why I am getting those moments in other directions while rotor is rotating using Z-axis.
Could any body please explain the reason?
