problem in the calculation of pressure drop for an axial turbine
 

Hi,

I am simulating an axial turbine. In this turbine, there are two domains.

The first domain is the piping before and after the blade and the second domain contains the turbine blades. The domain containing the blades rotates at 2000 rpm=209.43 rad/s while the other one is stationary.

I validated torque of turbine with experimental values but pressure drop at inlet and outlet of turbine doesn't validate with experimental value correctly. In fact, pressure drop is law and it should be higher. How do i solve this problem?

I am grateful that guide me about this case.
