摘要
Flow visualizations were carried out in a turbine rotor cascade with and without boundary layer fences, in order to provide an improved understanding of secondary flow and to show the fence effects. The oil flow and tuft screen methods were used. The results were supplemented by vorticity maps from hot-wire anemometry. Only a single separation saddle point was observed upstream of the blade. The distribution of passage vorticies at the exit from the cascade agreed well with the Oseen distribution under an appropriate normalization. The pressure side corner vortex started at the leading edge, while the suction side vortex began where the primary separation line of the horseshoe vortex intersected the blade suction surface.
