摘　　要：Using the code developed on the basis of the Navier-Stokes equations in conservative form expressed with nonorthogonal curvilinear coordinates and nonorthogonal velocity components, the 3D viscous flow field in an annular cascade was computed. The details of secondary flow and total pressure losses were predicted. The process of production, development and dissipation of passage vortices can be seen from the computed results.Using the code developed on the basis of the Navier-Stokes equations in conservative form expressed with nonorthogonal curvilinear coordinates and nonorthogonal velocity components, the 3D viscous flow field in an annular cascade was computed.
