I have tried the Vista CPD for new impeller design. However here I am interested to input Power/torque as one of the CFX inputs. Scenario is If I have one set of impeller and volute and 3 different electrical motors to run the pump, impeller geometry remains same in all 3 configurations and 3 motors have different rotor ( winding) configuration. thus varying the power input to pump. If i maintain same speed in 3 different motor I get 3 different H-Q curves in these 3 cases. so in CFD how do i consider this power input change with same speed?
