摘要：
Results of numerical investigations based on a 3D RANS solver FlowER, explaining the effects of geometrical and flow parameters on the development of endwall flows are presented. The blade height-to-chord ratio, flow turning in the cascade, inlet angle and radial distribution of pressure and profile load are considered here. It is also shown how the secondary flow patterns change in the case of non-nominal incidence at the suction side of the blade and due to interaction with shroud leakage and periodical turbine wakes.
