水轮机转轮三维粘性流动数值计算
摘要
对水轮机转轮内部三维紊流计算的基本方法进行了简要介绍
并采用贴体坐标下的有限体积法和k-ε模型
对丰满水电站7号水轮机转轮内部的三维粘性流动进行数值模拟
确定了转轮叶片的切割量
从而对7号水轮机转轮进行割边增容
收到了较好的效果
为老旧水轮机增容改造探索出一条新的道路。
Abstract
The basic method of 3-D steady turbulent flow simulation in the inner of Francis runner is introduced in this paper.Finite volume in the body-fitted coordination method and k-εmodel were applied to simulate the 3-D flow in the runner of Fengman Hydropower Station unit 7.The cut-off amount of railing edges of the runner blades were determined
therefore the output power was increased.It proved a new and effective way for old unit to increase its output.
