As an extension of the author’s previous work, this paper proposes a mixed iterative method for calculating the interactions of boundary layer with inviscid flow on S1 stream surface. It is shown from the comparison with experimental results that the iteration method given in this paper has a high calculation accuracy. In addition, the rate equation of the entrainment coefficient adapted for the turbulent boundary layer in the S1 stream surface has been established in this paper. The predicted results show that taking this equation as the supplemental equation for solving the turbulent boundary layer on cascade blades can improve the accuracy of calculation of the turbulent boundary layer on cascade blades.
