摘要：In the present study, the subgrid -scale (SGS) eddy-viscosity model developed by Vreman [Phys. Fluids 16 (2004) 3670] and its dynami c version [Phys. Fluids 19 (2007) 065110] are tested in large-edd y simulations (LES) of the inho mogeneous turbulent flow in a full passage of Francis turbine. Distributions of pressure, velocity and vortices as well as some flo w structure are gained, which is helpful to examine the performance of SGS model for complex turbulent flow and understand the flow characters in full passage of Francis turbine
