Abstract

Gas wave ejector (GWE) is an efficient ejection equipment using pressure waves to extract and transfer energy. However, at present, GWE is designed only for single condition, not fully utilizing the production capacity. The collaborative production mode using one equipment to work simultaneously under two different conditions was proposed to resolve this issue in this study, and was analyzed by combining numerical simulation and experimental test. The research results show that the collaborative mode almost has no effects on average total efficiency compared to single mode. In the range of tests, the efficiency difference between two modes is within 4.4%. The state parameters of the stable-pressure region (where channels are closed at both ends) on one condition are the initial parameters of the functional region on the other condition in collaborative mode, accounting for the difference between single and collaborative mode. The variations of performance parameters (ejection rate and the isentropic efficiency) with the medium-port pressure in collaborative mode was similar to that of the single mode. Thus, the performance parameters difference between two modes can be predicted by the relative relationship between the medium-port pressure and the average pressure in stable-pressure region of GWE in single mode. In conclusion, the collaborative mode improves the utilization of equipment while maintaining total efficiency, which can promote the popularization and application of GWE.
