Study on the Performance of Collaborative Production Mode for Gas Wave Ejector

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