torque coefficient

Post by yany »

Hello everyone.
I output the force on the blade of turbine in X and Y direction as well as the value of the torque on the blade. However, when I calculated the torque using the force, the result didn't match with the torque output. I'm wondering why did this happened? (the force in Z direction is 0).

Thank you very much.

Hello,

It is difficult to help you if you do not provide more details. Which values do you obtain ? How do you compute the torque from the force in your case ?

Did you visualize the force distribution on the walls (stresses surface variable) ?

Regards,

Yvan
