水轮机流道试验与研究

Test and Research of Turbine Flow Passage

开展水轮机流道试验与研究工作的关键在于水力流道的选择和翼型的设计,即在于选择最佳流道形状和最经济的相关尺寸,以使蜗壳、固定导叶、活动导叶、转轮以及尾水管内的水流流动畅顺,避免边界层脱流或产生二次回流.

The key of turbine flow passage test and research is the selection of hydraulic passage and the design of blade shape, that means selecting the optimum passage shape and the economic size, so as to make it to have smooth flow in the spiral case, stay vane, guide vane, runner and draft tube, and to avoid boundary layer separation or secondary back-flow.
