摘要
为了对混流(包括轴流和径流)式水力机械转轮内的三元流动进行分析,本文用分区组合法和坐标旋转法分别建立了混流式S_2流面不可压缩流动半反命题的组合式变分原理和统一的变分原理。
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.
