SPHysics Simulation of Experimental Spillway Hydraulics

Abstract: Abstract:In this paper, we use the parallel open source code parallelSPHysics based on the weakly compressible Smoothed Particle Hydrodynamics (WCSPH) approach to study a spillway flow over stepped stairs. SPH is a robust mesh-free particle modelling technique and has great potential in treating the free surfaces in spillway hydraulics. A laboratory experiment is carried out for the different flow discharges and spillway step geometries. The physical model is constructed from a prototype reservoir dam in the p… Show more

“…In addition, another significant force which must not be neglected in open channels is drag force. A kinematic similitude criteria should also include drag coefficient similarity [19]. With the combination of Chézy formula u C RJ = , the criterion is solved as [20],…”

“…The SPH method has been employed to investigate hydraulic jumps. López, Jonsson, and Gu et al [5][6][7] separately investigated the feasibility and capability of the SPH model in 2D hydraulic jumps on a flat as well as on a corrugated riverbed. Some inlet and outlet boundary algorithms for the SPH method were developed from the studies.…”

“…The majority of the dam and dike failures, with their causes and effects on losses of peoples' lives, are included in many research studies [5][6][7]. The overtopping failure is occurring due to overflowing water above dike crest into downstream slope and occurred as a result of different conditions such as high water level and the change of bed level [8] as well as the extreme hydrology conditions [9], inadequate rehabilitation works [10] and the efficiency of spillway design [11]. The breach channel failure, due to overtopping moment, has occurred as a result of unsuitable design of spillway, the spillway blocked, the losses of storage capacity of dike and higher soil displacement due to earthquake failure [12].…”
