The simulation of complex fluid flows involving large variations of the computational domain, constitutes an open challenge using most numerical techniques. The Particle Finite Element Method allows to merge the advantages of the “standard” FEM with the ones of meshless methods and it is naturally well suited to address this category of phenomena [3], [6]. At the current stage it still remains ...

The design floods of several reservoirs were recently re-evaluated and the revised spillway outflow could result in dam overtopping with catastrophic consequences for some embankment structures. Herein a physical study was performed on flat and pooled stepped spillways with a slope typical of embankments (θ = 26.6◦) and four stepped configurations were tested: a stepped spillway with flat horiz...

According to the study on shape of plunge pool in horizontal swirl spillway tunnel, design scheme a with better energy dissipation effect is proposed. Based hydraulic physical model test, which includes atmospheric pressure and decompression tests, combined different pool, measurement results fluctuating pressure. Main frequency sidewall are analysed. The show that inlet section connected by gr...

A dam spillway is a hydraulic structure that appropriately and safely diverts the outflow to downstream, so that the dam stability and passing of flood flows can be guaranteed. Compared to straight crest spillway, an Ogee spillway with curvature in plan in a fixed-width can pass more flow. Therefore under the low hydraulic heads and the need for a smaller place in plane, they are considered as ...
