Hi. I'm new to this softwere and trying to learn in day by day. Can anyone tell me why i am getting negative value of Cp in the graph? How can i solve this problem? I've attached a picture. Thank you.
The Cp is of a wind turbine is maximum for a unique TSR. TSR is given by the equation TSR = (omega*R)/ U; which means at higher TSR the inlet wind velocity is slow. That may be the reason for negative Cp.

At large TSR's the turbine is acting like a propeller and is adding momentum to the fluid resulting in a negative power coefficient.
