| 摘 要： | 提出在喷射器喷嘴内插入喷针来调节喷射器工作参数的方案,建立了可调式喷射器性能计算模型,计算分析了喷嘴截面积变化对喷射系数、气体压力、气体流量等参数的影响。结果表明,通过对喷射器喉口面积的调节,可拓宽喷射器的有效工作范围,减小喷射器入口参数对出口参数的影响。

| Abstract: | A scheme through measuring crush needle in the nozzle for adjusting the ejector was presented.A mathematical model for the performance of adjustable ejector was established and used to analyze the effect of cross section area variation of the nozzle on the parameters of entrainment ratio,fluid pressures and flow rate and so on.The results indicate that the outlet flow rate can be controlled within a stable extent by adjusting the cross section area of the nozzle,the adjustable nozzle can extend the effective working range of ejectors. |
