摘　　要：以带试验结果的NASA单级跨音涡轮为研究对象,对NUMECA商业软件中的四种湍流模型在相同条件下进行三维、定常数值模拟,并与相应的试验结果对比,分析各湍流模型对涡轮数值模拟结果的影响。模拟结果表明:一方程的Spalart-Allmaras模型计算稳定性和解的精度都相对较高,两方程的两个模型对于算例类涡轮数值模拟精度较差。To analyze the effects of turbulence models to the numerical solution of turbines in NU- MECA software,a NASA single-stage transonic turbine with experimental results has been chosen. In the research,three-dimensional steady numerical simulations have been conducted by four differ- ent turbulence models,and compared against experiment results.Numerical results show that the one-equation Spalart-Allmaras model is more stable and accurate comparing with the two different two-equation models for the test case.
