propeller (rotating body) study

amol wayse · October 27, 2012, 03:18

dear frnds, I am studying a propeller(rotating body). i have generated one rotating domain around the propeller and one outer control volume. i gave a fixed rpm for rotating domain and giving some translational velocity at VELOCITY INLET; my problem is i am getting same thrust for diff values of velocities at inlet. plz tell why so.
thnx in adv for ur suggestions.

Sounds like a boundary condition issue. Where did you put the velocity inlet? Can you post a picture of your domain and boundary conditions please?
