Hi, everybody!

I'm a newbie in CFD-simulations and faced a problem of imposing boundary conditions to a rotating axial rotor.
Where are two next questions:
1. What boundary conditions I have to impose on inflow and outflow boundaries? Inlet total pressure and static outlet? Or inlet mass flow and "I don't know what" outlet?
2. Must I correct the speed of rotor rotation depending on inlet mass flow? Or speed is constant and I just vary mass flow independently?

Thanks beforehand for your answers!
