Numerical Simulation for Hydraulic Characteristics of MLIS Hydropower Station

Combined with a multi-level intake structure, using the standard two-equation turbulence model to carry on the three-dimensional numerical simulation for the hydraulic characteristics of this intake .The flow velocity, fluid flow distribution and head loss were analyzed and summarized. The vertical velocity distribution near the intake has been significantly changed after placed stop log gate, the flow velocity of the reservoir surface water near the intake increases significantly, more surface water enter the power plant unit, and the head loss increases greatly.
