Angular velocity problem in pump flow
 

Hi, I am working on an axial pump and what I do is to show that my pump model is working.

For an internal flow with 0Pa inlet and outflow boundary conditions, I have a rotating impeller (290 rad/s) and I expect that to create a suction and flow through the outlet. However it doesn't.

Is there something that I miss or anyone had the same kind of problem ?

Noone has an idea ?
