Two-Phase Critical Flow

In the previous chapter, the mass efflux associated with an ideal, perfect gas was derived from six conditions/assumptions and equations for the first and second laws of thermodynamics; this model was then extended to a van der Waal gas. In this chapter, a homogenous equilibrium flow is derived and the effects of a non-homogenous flow is demonstrated. The chapter goes on to derive equations for critical flow associated with non-equilibrium flow where there may be non-equilibrium effects due to momentum, heat transfer, or mass transfer between phases.
