摘要

Sets of high-pressure ejection experiment were conducted to investigate the implementing of gases ejector with high-pressure condition. Numerical simulation was used to extend the study and overcome the limit of experiment facilities. Experiment shows that ejection coefficient of gases ejector was not sensitive to supply gas pressure changes. But which was affected greatly by backpressure in mixing cavity of ejector, as shown by simulation. The simulation result also implies that there are inherent relation between ejection coefficient, area ratio at inlet of mixing cavity and pressure different between supply gas pressure and the backpressure. And the relationship determines that in some range, the implementing of gas ejector was unstable.
