flow in circular pipe

February 18, 2003, 11:00

Hi everybody,

I'm simulating a flow in a circular pipe that has an impeller inside it at a mid length. The pipe is strength and both ends are open. It's lie horizontal in the air, which pressure 101325 Pa. When the work apply to impeller. The boundary condition of the outlet of the pipe is set to static pressure 0.0 Pa.( reference to ambient pressure). Which the inlet boundary condition should i set to the inlet portion. Give me a suggestion please.

Oh I see! It's must be a zero total pressure.
