| 摘 要： | 采用弱可压缩流体理论，大涡模拟数值方法，有限体积离散法，贴体坐标变换等理论和方法，研究了喷射泵内部流动状态。通过数值仿真，分别计算了具有不同喉管长度的喷射泵内部流场，并经过分析确定了喷射泵的最优喉管尺寸，计算数据和试验数据对比非常接近，证明了数值仿真结果是合理的、可信的。

| Abstract: | This paper studies the internal flow status of jet pump using the weakly compressible theory,such as large eddy simulation method,finite volume method and body fitted coordinate technique.Through the numerical simulation,the internal flow fields of jet pump are calculated under the condition of different throat lengths and the optimal sizes of throat are obtained.Compared with the experimental data,the computational results are proved to be rational and reliable. |

| Keywords: | Jet pump weakly compressible large eddy simulation throat optimization |
