| Abstract: | Oil-film technique and smoke streak method were used to study the secondary flow and vortex structrue in two kinds of turbine cascades. In the paper, the structrue of flow fields in these cascades are shown in the photographes, and are analysed systematically, which reveals the structrue of secondary flow and its development in these cascades, and provides the reliable material for understanding the production mechanism of secondary flow. |
