| 摘 要： | 以典型CAD软件UG为工具,结合数值模拟过程中网格划分和参数设置的要求,完成某种混流式喷水推进泵的几何建模,应用计算流体动力学程序对上述模型进行数值计算.CFD计算是针对泵整体流场控制体来进行的,而流场区域离散又衙要针对各结构部件分别处理,UG层设置功能能较好地协调两者处理时转换的不便.通过CAD软件和网格划分软件相结合解决了几何建模时叶轮叶顶间隙难以控制的问题.泵流场区域离散采用结构化网格.选取SST紊流模型,采用稳态多参考系方法进行计算.在设计工况和非设计工况下计算所得该混流泵性能参数均与设计所提供值有较好的一致性.

| Abstract: | Accounting for the demands in flow regions discretization and numerical simulation,a 3D modeling of a mixed flow pump used in water jet propelled ship is built by the popular CAD software UG.Numerical calculation is done with the popular CFD software,and calculated results on both design condition and offdesign conditions reach a good agreement with the manufacturer data.The shear stress transport turbulent equations and the multiple reference frame models are used simultaneously during the calculation.A go... |
