... present an unsteady and rotation speed, the shear layer formed by the blade sweep on the periodic phenomenon. The blade tip clearance leakage flow, leakage vortex and mainstream suppression have important turbine shroud wall becomes stronger. The shear layer hinders the effects on the film cooling...

... structures. The horse shoe vortices, tip leakage vortex, induced vortex, tip separation vortex and passage vortex were well captured and their interactions were interpreted. Fast Fourier Transformation was also applied to analyze the frequency signal in the flow field. Afterwards, the case with an upstream...
