Matching and optimizing the parameters of multistage equal pressure mixing ejector, the ideal ejector pressurization ratio and ejection efficiency are obtained, so as to improve the performance of multistage isobaric mixing ejector. Through mathematical analysis and experiment, the influence of single-stage ejector parameters on the performance is studied. The principle of determining the number of multi-stage isobaric mixed ejectors is clarified. The parameters influencing the performance of single- The results show that the matching and optimization of the induced Mach number, the temperature of the ejected gas, the ejector coefficient of the single-stage ejector and the pressurization ratio can significantly improve the performance of the multi-stage isobaric mixture ejector.
