Stream with built-in flash calculation



This model should be used when the vaporization fraction is unknown. The built-in flash calculation will determine the stream state as a function of the overall composition z, the pressure P and the enthalpy h. Additionally, the liquid composition x and the vapor composition y are calculated.
