| Abstract: | Using both the composite domain method and the coordinate rotation method, the composite principle and the unified variational principle are developed in terms of the stream function for the aerodynamic semi-inverse problem of incompressible flow along the mixed-flow S2 stream surface in this paper in order to analyse the 3-D flow field in the runner of mixed-flow ( including also axial and radial flow ) hydraulic machinery. |
