摘要

摘要: 采用具有TVD(total variation diminishing)性质的三阶精度Godunov格式、自由型曲面网格生成技术以及分区网格算法,对某型涡轮级进行考虑冷气掺混的全三维Navier-Stokes(N-S)方程数值求解,并将所得的结果与试验数据进行对比分析.通过分析数值模拟结果研究了该涡轮级所具有的气动特点.结果表明:所开发的快速、高效冷气掺混网格生成方法以及任意分区的流场求解算法可以满足工程上对气冷涡轮级的总体性能的快速估算及流场结构的详细描述.

Abstract: Using tree order precision Godunoc format with total variation diminishing (TVD) property,free-form surface grid generation technology and divided area grid algorithm,the three-dimensional(3-D)Navier-Stokers (N-S) equations considering cooled air mixing about one type turbine stage were resolved,and the numerical results were comparatively analyzed with the test ones.Through the analysis of the numerical simulation results,the aerodynamic characteristics of the turbine stage were investigated.The results show:the rapid efficient grid generation method considering cooled air mixing and the arbitrary division flow field algorithm can meet the engineering application on the overall performance rapid calculation and flow structure’s detailed description of air cooling turbine stage.
