Abstract：The numerical simulation of two dimensional transient turbulent flow in a guide vane passage of a Francis turbine was conducted based on the ALE(Arbitrary Lagrangian Eulerian) and dynamic mesh technology. The dynamical changes of the pressure and velocity were simulated by Fluent 6.3, using unstructured triangle grid, standard k-ε turbulence model and PISO algorithm as the guide vane was mo ving. The results show that the evolution of the flow field is unsteady with decreasing of the vane opening. Based on these researches, the eddy structures evolving spatially and temporally were visualized. The calculation provides some reference for vortex induced vibration in a complex turbulent flow of hydraulic machinery. The study is valuable for simulating the turbulence induced by the guide vane adjustment.
