本文试按照准三元理论用大型电子计算机对水轮机、水泵的内部流动进行了数值解析,并且,通过保角变换把奇点分布法应用到了翼间的流动解析上。计算;结果给出了轴面流线,叶片表面相对流速分布,压强分布,翼间流动状态等,为进一步研究转轮的性能,汽蚀与转轮设计打下了基础。 According to the quasi-ternary theory, this paper uses a large-scale computer to analyze the internal flow of hydraulic turbines and water pumps. And the singular point distribution method is applied to the flow analysis between the two wings by conformal mapping. The results show the axial flow lines, the relative flow velocity distribution on the blade surface, the pressure distribution and the flow state between the wings, which laid the foundation for the further research on the performance of the runner and the design of cavitation and runner.
