Thrust and torque of a propeller

October 17, 2006, 07:15

What is the easiest or most common method of determing the thrust and torque for a 3D propeller (my first CFD 3D experience). This was modelled using a rotating reference frame and periodic boundaries.

Thanks in advance,

Alex.

Report->Forces

That will output both the raw force and the coefficient. If you're working with coefficients, make sure you've set your reference values in Report->Reference Values.

Hope this helps, and good luck, Jason

excuse me!!!
what is the right refference area to get the right trust coeficient in proppelers?

Seems it's just the disc area described by the propeller. I know that's the case for helicopter rotors...
