outflow boudary condition
hello,
Why is the outflow boudary condition inappropriate for compressible flow ? In my problem, this condition seems good but the fluid is compressible. Could you help me? Thanks |
Re: outflow boudary condition
If you want to use outflow BC, you must sure that flow is really out of your domain that means no reverse flow happened.

Re: outflow boudary condition
If I am sure of no reverse flow but at the exit flow is supersonic compressible, is it a right choice in this situation, if no then anyother suggestion, thanks

Re: outflow boudary condition
No, you can only use pressure outlet for compressible flow simulations.

Re: outflow boudary condition
In external flow problems like flow over an aerfoil or on a cone usually before hand one is not known of pressure or velocity at the outlets, then how to use that pressure condition (for the case when I want to take outlet condition exactly at the body end)
