Abstract: To modify an axialflow runner based on CFD flowfield analysis results in order to prompt its properties. It is proved that the numerical simulated properties of the runner have a good agreement with the tested one. And accurate and abundant flowfield data are provided to the hydraulic runner modification. CFD flowfield analysis method improves the level of the hydraulic runner modification.

Key words: CFD, Hydraulic runner, Modification, Turbulence flowfield analysis
