Torque coefficient evaluation
 
Hi!

I was trying to analyse flow around a H-rotor, a type of vertical axis wind rotor. I made my rotor profile in gambit and set up the problem in fluent. I applied boundary conditions of velocity inlet, prerssure outlet, and farfield conditions. And I used K-epsilon turbulent model. I wanted to obtain the efficiency or power coefficient of the rotor. But the problem is that the torque coefficients, in the force monitor window section,were coming out to be negative.

I am really in deep problem,as I am not able to make any further progress.

I will be immensely glad and happy if someone of you suggests me solution to this.

PLZ DONOT LEAVE IT FOR OTHERS, AS IT IS YOU WHO CAN HELP ME.

THANKS!
