Analysis of Pressure Fluctuation in Draft Tube of Kaplan Turbine

摘要：

Based on a 3-D unsteady turbulent numerical simulation of the whole passage in Kaplan turbine, the unsteady flow field in draft tube was analyzed in this paper. The shape of vortex rope in draft tube was studied. The pressure fluctuation in draft tube was analyzed by the characteristics of amplitude and frequency.
