Abstract

Based on two families of relative stream surface theory, the differential and integral equations of the endwall boundary layer in the S2 stream surface (hub to tip stream surface ) have been established in the orthogonal curvilinear coordinate system in the present paper. By directly associating the blade force defects with the warping of 32 stream surface near the endwall, we have proposed a new method for predicting the endwall boundary layer.. � This method can be used to conduct the interactions of the end wall boundary layer with the 32 stream surface potentisl flow, in order to get the iterative solution of the end wall boundary layer flow with the potential flow in $2 stream surface. The predicted results � have
