中文摘要：

对气液射流泵的工作流体为气体,引射流体为液体的特点,参考一般射流泵的研究方法,对气液射流泵在不同喉嘴距和面积比下的性能进行了数值模拟分析。固定工作气体压力和扬程,以气液射流泵引射流体流量的能力为参考依据,判断出气液射流泵的最佳喉嘴距和最佳面积比。结果表明,喉嘴距和面积比参数对泵引射流体的能力有很大影响,当喉嘴距为1倍喷嘴直径、面积比m为4时,气液射流泵的引射流量最大为0.6 L/Min。并且将数值分析结果和试验结果进行了对比,吻合较好,说明数值计算是可靠的。

英文摘要：

We refer to the general research methods in jet pumps,simulate numerically the performance in different nozzle-to-throat clearances.Keep the working gas pressure and the head of jet pump in a fixed value,and take the ability in drainage fluid flow of jet pump as a reference data,and determine the best nozzle-to-throat clearance and area ratio of gas-liquid jet pump.The results show that nozzle-to-throat clearance and area ratio parameters have great influence on the ability of the gas-liquid jet pumps,and while the nozzle-to-throat clearance is 1 times of nozzle diameter and the area ratio is 4,the gas-liquid jet pump has maximum flow,is 0.6L/Min.And the numerical results and experimental results are compared,indicating that numerical calculation is reliable.
