中文摘要：

对比研究了六个常用的湍流模型预测压气机转子叶尖复杂旋涡流动的能力，选用的六个湍流模型分别为：混合长度模型，SA模型，标准κ-ε模型，SSTκ—ω模型，-↑v^2-f模型和雷诺应力模型。通过与压气机转子尖区典型的大尺度旋涡结构-泄漏涡和角区旋涡的SPIV详细测量结果的对比，分析了六个湍流模型预测转子尖区复杂流动的能力；在结合试验的基础上，根据数值模拟结果对转子尖区流动进行了更为深入的分析。

英文摘要：

Six turbulence models frequently used in compressor aerodynamics, including the Mixing- Length model, the Spalart-Allmaras model, the standard κ - ε model, the SST κ - ωmodel, the -↑ v^2 - f model, and the Reynolds stress model, have been employed in the detailed numerical investigations of a low-speed large-scale axial compressor rotor, whose tip flows have been measured in detail with Stereoscopic Particle Image Velocimetry, to assess the predictive capabilities of the turbulence models for large-scale vortices in the tip region of the rotor. The flow fields in the rotor tip have been also further analyzed based on the numerical results combined with the experimental results.
