| Abstract: | In this paper,the variational principles and generalized variational principles for the hybrid problems ( types A, B, and C) for incompressible flow in airfoil cascades on a running cylindrical surface have been developed in terms of two functions-the angular function and the moment function. The aim of this paper is to provide a theoretical basis for designing the blades of axial hydraulic machinery by employing the FE method et al. |
