| 摘 要： | 研究了应用于液-液气两相流引射器的特性,建立了引射器气液两相湍流流动的数学模型,进行了以液体为工作流体,同时抽吸气、液两相介质的二维全流段数值仿真。重点研究了不同混合室长度对引射器性能的影响,结果表明,当混合室长度lH=6d3(混合室直径)时,气液两相流体混合较为均匀且沿程损失较小,还可满足经济性要求,因此lH=6d3为最佳混合室长度尺寸,此时引射器中的流体具有明显的射流特征。

| Abstract: | The liquid-liquid gas ejector was discussed.The mathematical model of the turbulence flow of two phases(gas and liquid) was constructed.Based on the liquid working flow,the numerical simulation of two-dimensional flow field with pumping both gas and liquid synchronously had been made.The influence of mixing room with different length on the ejector's performance was studied primarily.The result indicated that,when lH=6d3,the gas and liquid were mixed uniformly and the economic requirement was fulfilled,so lH=6d3 was the optimum length of mixing room,and the flow in the ejector presented clear turbulent jet characteristic. |
