摘要

摘要: 简要阐述了三维雷诺平均Navier-Stokes(RANS)方程求解程序中使用的对流迎风分裂格式改进形式(AUSM+)以及Spalart-Allmaras(S-A)一方程湍流模型,然后对Sajben收缩扩散通道内跨声速流动和高速透平静叶排内部流动进行了数值模拟,并将数值结果与实验结果进行了比较,结果表明自主开发的三维RANS方程求解程序可以准确模拟复杂的内部流场.

Abstract: The AUSM+ (advection upstream splitting method+) and one-equation Spalart-Allmaras (S-A) turbulence model used in the present in-house three-dimensional Reynolds averaged Navier-Stokes (RANS) flow solver were briefly described.The transonic flow in the Sajben converging-diverging duct and the flow in the stator passage of a high turning turbine were simulated to verify the code.The results show that the present solver can be used to simulate accurately the complex internal flow fields.
