I am trying to solve a transonic heat transfer problem in a concentric tube arrangment. I am having a problem in setting boundary conditions and in achieveing convergence.
At the inlet, a mass inlet boundary condition is applied, and on the outlet a pressure outlet BC is applied, which should be when in the transonic domain. But I am bit confused with supplying the pressure values.
Can somebody guide me on how to achieve convergence in this transonic heat transfer problem?
