Default inlet boundary conditions for subsonic flow

Hi there,

I would like to implement the inlet boundary conditions for a subsonic flow. I would like to use mass flow rate(mdot), as well as static pressure as the fixed parameters since they are the only known ones. The first question is whether this group can work or not. I do know that only one of the thermaldynamic state parameter can be used besides velocity or mdot in the subsonic case.

2. I am doing with multi-species, so extrapolation has to be done. But how?

3. Can somebody shed some light on some books or papers reviewed the boundary conditions implementation?

Thanks a lot.
Paul

You can look at this paper if you have not read it already.
