sir,

I am modeling a centrifugal fan impeller. I know the experimental results for suction pressure, discharge pressure and mass flow rates. What inlet and outlet conditions should i specify....Please help

if you give somewhat more info on the setup and the available flow conditions, we probably can help you with this.

kind regards, Laika, still orbiting

Thanks for the response.... I have modelled an impeller with axial in flow and radial out flow. It is used to suck air to a unit. I have the experimental values for mass flow rate , inlet pressure and outlet pressure.

I'd apply a mass flow inlet and a pressure outlet.

If you can calculate the inlet toal pressure, I'd do a pressure inlet -- pressure outlet simulation as well, to see if the calculated flow rate matches experiments.

good luck,

Thanks very much... By inlet total pressure u mean suction head+ dynamic head ?
