CFD of pump
 

Hello all,
I am doing a cfd analysis of a verticallly mounted pump.. I have completed the geometry and meshing...i am using MRF model for the solution.. i have used the velocity inlet and pressure outlet as boundry conditions... the solution i obtained gives the sucction pressure more than the discharge pressure.. i think fluent is not adding the energy given to the liquid by the pump...(k-E standard and k-E realizable both give the same result)

if anyone knows about this kind of problem plz help....

Have you rotation taken effects of the domain into account ?
