Résumé

This paper presents a coupled two-phase flow model for simulation of submerged flow bridge scour under dam-break flows considering the sediment-fluid interaction. The Smoothed Particle Hydrodynamics (SPH) method is employed to simulate the sediment and fluid movements based on the Newtonian and non-Newtonian fluids, respectively, in the framework of two-phase flow modeling. The SPH simulation based on the treatment of Bingham-type Herschel-Bulkley-Papanastasiou constitutive model and the Drucker-Prager yield criterion is used to predict the sediment transport and the scour depth time histories under a submerged bridge deck. The influence of parameters such as geometry of the bridge deck and flow conditions on the scour depth is also investigated. © 2019 the Author(s).
