The nozzles for one-component two-phase flow are used in the total-flow system, which applied to the geothermal and the waste heat recovery power plants. Thermal energy can be transformed into kinetic energy by the nozzle. We have been investigating subsonic mist flow with velocity and temperature relaxation phenomena in a convergent-divergent nozzle in order to elucidate the critical flow and shock waves in it. In this paper, phase change (boiling) is taken into account, which is one of the most important phenomena in one-component two-phase flow. It is shown that phase change can increase the velocity of the two-phase flow, but not affect the feature of shock waves in subsonic flow.
