Engine BC
 
Hi,all I'd like to simulate an aircraft with some engines. To compute reasonably, I'd like to know the best boundary conditions for inlet and outlet of the nacelle.

For inlet, is subsonic outlet condition (fixed static pressure and the others extrapolated) enough? Does it meet mass flow rate to a specific value?

For outlet(cold jet), I have seen fixed pressure with freestream static pressure. Is it realistic?

Please tell me your opnion.

Best regards, kei-tee
