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.
