Abstract
Sluice gates are widely used for flow control in open channels. Flow under a gate is complicated with a rapidly varying free surface and dynamic pressure distribution. Due to this complexity most of the studies to date are based on physical models. In the present study the flow under sluice gates on a flat plate is modeled numerically. Owing to the capabilities of SPH model in simulating rapidly varied free surface flows, this lagrangian method was applied in the present study. The SPH model was further developed by introducing IXSPH and an innovative method was proposed to simulate the constant inflow discharge. The present model results for free surface profile, as well as velocity and pressure field indicate good agreement with experimental and existing Eulerian numerical results. In the present work, the contraction and discharge coefficients were also captured for different opening ratios and gate inclinations. This study shows the ability of the developed SPH model as a useful tool in designing hydraulic structure.
