摘要
本文用三维激光多普勒测速技术测量了平面扩压叶栅的叶片吸力面角区流动湍流特性，如紊流动能分布、雷诺应力分布等．分析了角区内流向涡和通道涡对湍流特性分布的影响，结果表明：流向涡的核心区域及旋涡与附面层相互作用区域的湍流动能增加．同时，旋涡和旋涡运动强烈影响着雷诺正应力和切应力的分布规律．
The turbulence characteristics of flow in the junction region of the endwall and the suction surface of blade of a compressor cascade passage were measured by using a three-dimensional Laser Doppler Velocimetry system. The result indicated that the turbulence kinetic has a maxima in the core regions of the streamwise vortex and regions that interacted between the vortex and boundary layer, and the vortex or motion of the vortex has strong influence on the distributions of the Reynolds stress.
