Boundary Condition Confusion
 

Hello Everyone,

I am a student of IIT Kharagpur, I am trying to simulate an underwater vehicle which is ejecting air out from its mouth/nose. I am wondering which boundary condition is to be used at nose/mouth of this vehicle where from it is ejecting out air.

I will be very thankful to the one who can help or suggest me something substantive in this matter.

Thanks,
