Inlet Boundary Conditions for Propeller Inflow

I am in the process of simulating a UAV propeller in a hover condition - therefore the inlet velocity is driven only by the suction of the propeller. I am simulating the propeller itself in a MRF zone. Incompressible, SIMPLE solver.

What are the correct boundary condition types to be used in the inlet and outlet in this case?

So far I am considering a pressureInletOutletVelocity for U inlet, and totalPressure for P inlet.
InletOutlet for V outlet, and fixedValue for P outlet.

Hi, this is Fillia!

The common way here is a velocity inlet and a pressure outlet (gauge pressure of 0 Pa) boundary condition. However, it would be great if you could also share the link to your project so I can check :slight_smile:

Best regards,
