This paper presents a Finite Element Method for the calculation of the low system through component parts in water turbines or pumps with coordinates. The calculation concentrates on the absolute flow field. The boundary conditions of moving cascades in the absolute flow field are discussed. The method may he applied to cases either with or without relative motion for ring and straight multiple cascades. A new approach to the study of mutual influence of one part on another and the related unsteady...

The paper presents detailed test and research results of some high loading transonic stationary and moving cascades for the first time by the shallow water through analogy in China. These results are compared with circulation calculation and plane cascade wind tunnel tests. The shallow water through analogy has advantages of exactness, visualization, simplicity and economy valuable in the concept design and qualitative analysis stage of transonic turbine cascades. Not only can a high velocity wind tunnel test be avoi-ded.,but the credibility of transonic cascade calculation results can also be verified by this method.
