hi friends ,

1. i have a centrifugal pump which is immersed in a tank that is full of water
the pump has two inlets and both these join to form one outlet which is the delivery from the tank

2. you can imagine the pump as a small vertical cylinder having inlet at its top
and bottom faces , the outlet simply comes out as a pipeline from its
curved lateral surface. This whole lies at the bottom of a full tank.


is there any way by which we can model the centrifugal pump in CFX pre without having to bother about its actual impeller , volute etc and doing it as a rotating domain - stationary domain problem?

i am trying to use the 'additional interface' models [ giving mass flow rate at each ]

any ideas/ experience on this kind of problem ..?

thanks & regards

Sandeep
