Autor: Sven Smolders, Maria João Teles, Agnès Leroy, Tatiana Maximova, Patrick Meire, Stijn Temmerman
Publikováno v: Journal of Marine Science and Engineering, Vol 8, Iss 1, p 27 (2020)
There is increasing interest in the use of nature-based approaches for mitigation of storm surges along coasts, deltas, and estuaries. However, very few studies have quantified the effectiveness of storm surge height reduction by a real-existing, est

Overview of Large-Scale Smoothed Particle Hydrodynamics Modeling of Dam Hydraulics
Autor: Damien Violeau, Andreia Moreira, Agnès Leroy, Francisco Taveira-Pinto
Publikováno v: Journal of Hydraulic Engineering. 146
The design of appurtenant structures for dams, such as spillways, is a complex task because of the turbulent high-velocity aerated nature of the flowing water. In previous years, physical m...

A SPH elastic-viscoplastic model for granular flows and bed-load transport
Autor: Martin Ferrand, Antoine Joly, Agnès Leroy, Damien Violeau, Alex Ghaïtanellis, Kamal El Kadi Abderrezzak
Publikováno v: Advances in Water Resources. 111:156-173
An elastic-viscoplastic model (Ulrich, 2013) is combined to a multi-phase SPH formulation (Hu and Adams, 2006; Ghaitanellis et al., 2015) to model granular flows and non-cohesive sediment transport. The soil is treated as a continuum exhibiting a vis

Mixture model for two-phase flows with high density ratios: A conservative and realizable SPH formulation

International Journal of Multiphase Flow, Elsevier, 2019, 111, pp.158-174. ⟨10.1016/j.ijmultiphaseflow.2018.11.007⟩
International audience; The numerical modelling of two-phase mixture flows with high density ratios (e.g. water/air) is challenging. Multiphase averaged models with volume fraction representation encompass a simple way of simulating such flows: mixtu

Air entrainment within water is a common feature of flows over hydraulic works – spill over a dam, wave breaking on a dike, etc. – and its accurate modeling is a key to better design such structures. The Smoothed Particle Hydrodynamics (SPH) meth
