摘要

Abstract

Based on N-S equation and standard k-ε turbulence model, CFD computational fluid dynamics software was adapted in two-di mensional steady numerical simulation for internal flow of volute, guide vane and turning wheel of HLA616-WJ-55 axial flow turbine, and the results were compared and analyzed with three-dimensional numerical simulation of the same turbine type. The results showed that the internal flow rule of volute of two-dimensional was consistent with three-dimensional numerical simulation, and the distribution of pressure and speed were uniform, the flow condition was better. Two-dimensional CFD analysis could predict the structures of internal flows of volute, guide vane and turning wheel roundly, and numerical simulation results had important directive significance to turbines selection and optimization design.
