centrifugal pump
Hi Experts, I want to simulate a centrifugal pump. I have experimental flow characteristics of the pump and I have to veryfy those in CFD. Now my question is what BC combination I should use for successful simulation?

Inlet vs outlet (split=1) or pressure vs -ve inlet at outlet or any other. Desperately waiting for ur guidance.

Re: centrifugal pump
You can use:

1) pressure - pressure

2) inlet - pressure

3) stagnation - pressure

I usually use 1) and look for the mass flux. Going this way your flow will be reversed for the first iterations.
