Confined jets of two-phase mist flow are important in the development of a two-phase ejector for the refrigeration cycle. However, the flow characteristics of the two-phase ejector have not been elucidated to date due to the nonequilibrium of velocity and temperature. In this study, the mixing characteristics of two-phase mist flow in the two-phase ejector were investigated experimentally. The pressure increases in the mixing section and the diffuser of the ejector were measured. The following results were obtained by comparison of the measured pressure increase with that calculated using a simple theory. Increasing the length and decreasing the diameter of the mixing section were effective for raising the pressure. The energy efficiency of the two-phase ejector used in this experiment was approximately 10%. This efficiency should be increased by improving the mixing characteristics of the ejector and the nozzle efficiency.
