摘　　要：针对射流泵基本理论研究方面存在的问题,应用计算流体力学(CFD)中PHOENICS软件建立射流泵几何模型,采用正交非等距网格划分方法,模拟射流泵的内部湍流场,研究了流量比、喉嘴距对速度的影响,以及喉嘴距对湍动能的分布影响,得出射流泵基本性能曲线,与文献给出结果吻合较好。完善了射流泵的基本特性研究,分析了射流泵流场中能量分布,为进一步进行射流泵研究提供可靠依据。Against the existing problems with the basic theory of the present research on the jet pump,the geometric models of a jet pump are established in CFD software PHOENICS,by applying non-isometric orthogonal grids to simulate the influence factros in the flow field of the jet pump,conducting researches on the rate of flow and the throat influence on the speed and the distribution of turbulent kinetic energy.The basic performance curve of the jet pump is obtained,which is in good agreement with the literature results.The results show that the basic characteristics of the jet pump is improved by analysing the energy distribution in the flow field of the jet pump,thus providing reliable reference for a further study of the jet pump.
