基于CFD的水轮机密封内部流场的研究

Research on Inner Flow Field in Labyrinth Sealing of Hydraulic Turbine Based on CFD

基于计算流体动力学的(CFD)计算软件fluent,利用RNGk-ε湍流模型对某水轮机迷宫密封内部流场进行了数值模拟,得到了密封内的流场分布,为进一步研究水轮机密封内部流动提供了依据。

Based on CFD code-Fluent, Using RNG k-ε turbulence model to study the inner flow in labyrinth sealing of hydraulic turbine. The flow structure in the seal is obtained, which shows the property of resistance enhancement of labyrinth sealing by turbulence.
