| 摘 要： | 本文首先用反推法建立了S_2流面不可压缩流动全正命题的变分原理和广义变分原理,然后进一步用反演变换建立了A类杂交命题的变分原理族,旨在为用有限元法和各种变分直接解法进行水轮机、水泵和风机叶轮的设计、改型及流场分析提供新的理论基础。

| Abstract: | The variational principles are derived for the full-direct problem of an incompressible flow along a S2 stream surface by means of the inverse-deduction method, and based on them the VPs are also developed for the Type-A hybrid problem by applying the inversive transformation. The paper aims at provision of a new theoretical basis for the design, modification and flow analysis of runners of hydraulic turbines, pumpl and ventilators by the FEM and all kinds of direct variational methods. |
