本文阐述了列宁格勒金属工厂采用的设计混流式水轮机叶片的基本方法。在计算中,开始认为混流式水轮机的叶片是由无限薄和无限多的叶片所组成(鲍氏的轴对称计算法),然后再考虑叶片的有限厚度对液流的排挤。М.Я.Байер是首先提出在水轮机叶片计算中考虑排挤的想法。此时作下述几点基本假设: 1.液体是理想的和不可压缩的。 2.在转轮流道内液流是轴对称的,即 This article describes the basic method used to design Francis turbine blades for the Leningrad metal plant. In the calculation, we begin to think that the vane of a Francis turbine is composed of infinitely thin and infinite blades (Axial symmetry of Bowser) and then considers the finite thickness of the vane to squeeze the flow. М.Я. Байер is the first to propose the idea of ​​squeezing out in turbine blade calculations. Here are some basic assumptions: 1. The liquid is ideal and incompressible. 2. In the runner flow path is axisymmetric, that is
