Let say the domain reference pressure is 1 atm (atmospheric pressure). May I know the input value of relative pressure if I change the flow from subsonic to supersonic (k-epsilon model)? Is it equals to 0 Pa or pressure of that particular equipment during release?

It depends on the flow configuration, so your question is unanswerable. It sounds like you need to do some reading about compressible flow as your question is probably a standard compressible flow equation.
Also the reference pressure is used to reduce numerical round off errors in the simulation. It tells you nothing about the flow conditions. |
