Calculation of two-phase dispersed droplet-in-vapor flows including normal shock waves

Quasi-one-dimensional, steady state, two phase dispersed droplet-in-vapor flow calculations have been developed. The technique is applicable to both subsonic and supersonic single component flow in which normal shock waves occur, and is the basic for a two dimensional model. The flow is assumed to be inviscid except for droplet drag. Temperature and pressure equilibrium between phases is assumed. Example calculations of flow in one dimensional nozzles with and without normal shocks are given and compared with experimentally measured pressure profiles for both low quality and high quality two-phase steam/water flow.
