hi all
I'm speaking about simulation of VAWT (2d) although posts in this site related to VAWT complaining of high torque , I'm facing very low torque values for some low TSR values and for high values of TSR the average torque is completely negative.
Is this related to reference values in fluent ( Area, length , Depth,...) or some thing else.?
what Does negative torque mean?
I'm writing my master report and I'm really don't have much time?
