摘要
利用求解雷诺平均NS方程的数值途径模拟带前置定子导管螺旋桨周围的流场,其中网格系统采用卡笛尔的网格和四面体/棱柱体网格相结合的方式,这样较好地保证了网格的质量和正交性,利用混合面技术处理转动部件和非转动部件间边界条件。通过与LDV的流场测试结果的比较,表明文中采用的数值方法可以较好地模拟复杂组合推进器内的流动过程,为设计性能优良的工程产品服务。
In this paper,the numerical approaches for solving reynolds averaged NS equations to simulate the flow field in front of the stator duct tape around the propeller.Among them,the grid system uses Cartesian grid and tetrahedral/prism mesh combination which ensures a better quality of the mesh and the orthogonal.The mixing-plane technology is used to deal with the boundary conditions between rotating and non-rotating parts.By contrast with the LDV flow field test results,the numerical methods used in this paper can better simulate complex combination of propulsion flow process inside and provide services for designing performance engineering.
