Centrifugal pump boundary condition
i am simulating centrifugal pump problem in fluent13. i solved tutorial given by fluent on mrf, but in my case when take B.C. as pressure inlet and pressure outlet for inlet and outlet for pump it shows wrong pressure distribution. i want simulate above problem for different mass flow rate and plot the graph bwtn presure rise vs mass flow rate ( which is input data given by customer), so plz tell me what appropriate boundary condition so that a use mass flow rate as input data .
in inlet to pump pressure distribution is not const
but for development flow velocity const is real
by velocity inlet u can get pressure in inlet and for a specific pessure inlet u should try with various velocity and compare with desire pressure
