摘要:

采用任意曲线坐标系对含有Ｖ型稳定器的通道内湍流流场进行数值计算。对含有Ｖ型槽的复杂流场中网格分区方法作了详细的分析，提出一个新的网格划分方法。数值计算采用曲线坐标系下非交错网格的ＳＩＭＰＬＥ方法，计算时对整个流场进行分区迭代，直到得到收敛结果。文中对一含有Ｖ型稳定器的直通道湍流流场进行了数值计算，结果合理。

Abstract:

The turbulent fields in ducts with V stabilizers were calculated using the zonal grid methods of generalized nonorthogonal curvilinear coordinate systems.Grid generation was from the zonal method and detailed analysis was conducted on how to generate the grids of complex geometry such as ducts with stabilizers.Some new methods to generate grids are given in this paper.The SIMPLE method under curvilinear coordinate is used with nonstaggered grid system.Computation of all the zones is conducted until the convergence is obtained.The turbulence fields in ducts with V stabilizers are computed and the gained results are reasonable
