Moment coefficient of vertical axis wind rotor
 
Hi, I am using fluent package for flow simulation past vertical axis wind rotors. I am using k-epsilon turbulent closure model. My problem is that the moment coefficients are coming negative, and too, in high range!! But for proper simuation it should be positive two digit numbers. I tried other turbulent models as well. But did not work out!

I am really in dilema as to what to do!

Please help me.
