摘　　要：本文利用激波管平面叶栅风洞在来流总压PO=1602×105 Pa、2.077×105Pa,相应总温TO=338.5 K、373.0K条件下进行了某叶型叶表压力分布、热流率分布测量实验。同时对实验段、实验叶栅进行了气动、传热方面的数值模拟。采用多种湍流模型计算并与实验数据比较后,发现采用spalart-Allmaras湍流模型计算所得叶表热流率与实验数据变化趋势一致。The distribution of statistic pressure and heat transfer ratio on the surface of cascade under conditions of ?? = 1.602 x 105 Pa ? 2.077 x 105 Pa with correspondent inlet total temperature TO ? 338.5 K ? 373.0 K were measured and simulated. To verify the results of each other, experimental data and computational results involved several different kinds of turbulence models were compared and it is found that computational results using Spalart-Allmaras turbulence model agree well with the experimental data.
