Hi there

I am simulating flow in a centrifugal pump using MRF in fluent. But I am getting almost constant or rather increasing total head with increase in flow rate at constant RPM. However with increase in speed the total head increases i.e. I am getting a almost constant value at a particular speed irrespective of the flow rate.
I have tried all the BC combinations, I can think off. I have tried
- mass flow inlet and pressure outlet
- mass flow inlet and outflow
- pressure inlet ad pressure outlet

But the results are coming the same.

Can anyone shed some light on this problem.

Thanks a lot in advance.
