| Abstract: | The author introduced the turbine model acceptance test for the efficiency, output, cavitation, pressure fluctuation, runaway, hydraulic axial thrust, hydraulic wicket gate torques and Winter-Kennedy differential pressure of the Francis turbines to be equipped at Baise multipurpose dam project. Detailed analysis and discussion are also conducted for the key technical issues such as Karman vortex, channel vortex and exceptional pressure fluctuation. Emphasis is put on the three different definitions for plant cavitation coefficient and their influence on the pressure fluctuation test. The effect of cavitation coefficient on the similarity between prototype and model turbine is also discussed. |
| Keywords: | Turbine model acceptance pressure fluctuation plant cavitation coefficient channel vortex |
