Three-Dimensional Numerical Simulation for Runners with Long and Short Blades of Turbine
摘要
Abstract
The Standard k-ε double equation turbulent model and 3D time N-S equation were used to carry out the 3D turbulent numerical simulation study on the flow field of runners with long and short blades (HLA351) of mixed flow turbine and gained the flow speed and pressure intensity distribution in the flow channel. The results showed that compared to the common runner, the runner with long and short blades has better flow pattern and reasonable distribution of flow speed and pressure intensity. The CFD analysis on the whole channel of turbine can accurately forecast the properties parameters and internal flow field structure in the overflow parts of turbine.关键词
