摘要
提出了一种多喷嘴无扩压室引射器的性能计算方法。通过模拟仿真和试验验证的方法对计算结果进行校核,结果表明计算误差率小于10%,满足工程设计需求,为多喷嘴无扩压室引射器的工程设计提供了理论依据。
The method of multi-nozzle and non-diffuser chamber ejector ratio calculating is given in this paper.The results checked by simulation and experimental verification,show that the calculation error is only 10%,which can meet the needs of engineering design.It provides a theoretical basis for the engineering design of the multi-nozzle and non-diffuser chamber ejector.
