摘要：
The thermodynamic performance potential of a kind of jet refrigeration system using pressurized hot water flashing nozzle flow as the driving flow in two-phase ejector is first re-commended by the analysis and calculation. The design method of such two-phase flow nozzle is developed by the thermo-fluid dynamic analysis of the basic equations derived from the basic flow mechanism and the flow model suggested. Design solution by Lunge-Kutta method is studied. The test results of the designed and tested models show that the distribution of pressure and temperature along the nozzle flow path is well closed to the numerical solutions which proves the effectiveness of the method for applying to the new refrigeration system design.
