Abstract:
A simplified analytical model for two-phase subcritical flow in orifices is provided. Critical choking conditions are obtained as a limit case. Using one-dimensional separated flow equations, the downstream flow is shown to depend on stagnation properties and on an overall friction coefficient characterizing the orifice geometry. The model allows for thermal non-equilibrium and for relative motion between the two phases. The results are readily applicable as design tools.
