水力机械转轮内完全三元Beltrami流动杂交命题的变域变分理论

Variational Principles for Hybrid Problems of Fully 3-D Beltrami Flow in Runners of Hydraulic Machinery Based on Variable Domain

本文建立了旋转叶轮内完全三元不可压缩流动杂交命题的变域变分理论。与文献[1]相比,本文具有边界条件简洁合理和适用范围广等特点,旨在为水力机械转轮的三元流动设计、改型及流场分析提供更为完善的理论依据。

A theory of hybrid problems has been established for fully 3-D incompressible flow in a runner based on variational principles in variable domain. Compared with the ref. [1], this paper features the rational and simple boundary conditions and wide applicability. It aims to provide more consummate theory for the 3-D flow design, modification and field analysis of runners of hydraulic machinery.
