I am having problem in defining boundary condition for CD nozzle. Inlet pressure is given as 80 bar, inlet temp is given as 1583 K and inlet velocity is 186 m/s. Pressure at outlet is 13 bar.
However in fluent there are condition like supersonic gauge pressure inside pressure inlet condition. For which I have no clue. While I am giving BC, the solution is diverging. What condition should I prescribe? I have to use K- Epslion model, with 1% turbulent viscosity. |
