Dear friends, I am conducting a CFD analysis on regenerative pump using ANSYS CFX (MRF approach). Please see the model attached. http://s9.postimg.org/cugg0fogv/image.jpg
The model consists of 3 regions- inlet domain ,impeller domain and outlet domain.
Impeller is rotating at 2800 rpm. At inlet , total pressure =101953pa and at outlet, mass flow rate =0.76kg/s .
The pump is expected to produce 25 m head.But from analysis it is found that ,pressure at the outlet of the pump is negative.
See the pressure distribution> http://postimg.org/image/7t53erj3j/
Can anyone help me with this problem...
Thanks in advance..

You will need to show details of cfd domain geometry, boundary conditions and interface modelings.
