Propeller torque
 
Hi everyone, i've computed a solution for a propeller using a single rotating reference frame, i.e. the propeller is stationary and the flow rotates about the propeller. I need thrust and torque parameters, and am comparing these to experimental values.

The thrust was found from: Report-->Forces, and specifying the direction of thrust. This is a reasonable result.

Because the flow is rotational and the blade is stationary, i'm not sure I can just report a force in torque (drag) direction of the propeller blades. Is there any way to report a result in a different reference frame? or is there a standard method in determining the Torque of a propeller blade?

Thankyou in advance!

Alex.

Re: Propeller torque
 
My apologies, torque is a moment of course. too late at night.

Well this makes my question much simpler:

when you report the moment about the specified axis, the results are presented as: (number1, number2, number3). Does this represent moments about (x,y,z) axes? i.e. does "number3" represents the torque about the z-axis?

thanks,

Alex.
