Hydraulic Performances of Stilling Basins with Step-Down Floor Combined with Flaring Gate Pier by Numerical Simulation
摘要
Abstract
Three-dimensional RNG κ-εturbulence model with VOF method was used to study the stilling basins with step-down floor combined with flaring gate pier and other two comparative schemes of stilling basin and stilling basin combined with flaring gate pier. Water surface profile, velocity field and pressure distribution on the stilling basin floor were obtained. The results show that the stilling basins with step-down floor com-bined with flaring gate pier has better hydraulic performances such as more sufficiently diffused and aerated in all directions,more turbulent flow, smaller velocity at the bottom of the stilling basin,smaller pressure and more even distribution on the stilling basin floor.关键词
