Abstract
To understand the influence of streamwise vortex on turbulence characteristics, the turbulence characteristics of flow in the corner region 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 normal stress and shear stress.
