Well-posedness and potential-based formulation for the propagation of hydro-acoustic waves and tsunamis
Juliette Dubois, Sébastien Imperiale, Anne Mangeney +1
We study a linear model for the propagation of hydro-acoustic waves and tsunami in a stratified free-surface ocean. A formulation was previously obtained by linearizing the compres…
Benchmarking Exercises for Granular Flows
Antoine Lucas, Anne Mangeney, François Bouchut +2
For the 2007 International Forum on Landslide Disaster Management framework, our team performed several numerical simulations on both theoretical and natural cases of granular flow…
Experimental assessment of the effective friction at the base of granular chute flows on smooth incline
Olivier Roche, Siet van den Wildenberg, Alexandre Valance +4
We report on direct measurements of the basal force components for granular material flowing down a smooth incline. We investigate granular flows for a large range of inclination a…
Acoustic emissions of nearly steady and uniform granular flows: a proxy for flow dynamics and velocity fluctuations
Vincent Bachelet, Anne Mangeney, Renaud Toussaint +3
The seismic waves emitted during granular flows are generated by different sources: high frequencies by inter-particle shocks and low frequencies by global motion and large scale d…
Modelling iceberg capsize in the open ocean
P. Bonnet, V. A. Yastrebov, P. Queutey +6
At near-grounded glacier termini, calving can lead to the capsize of kilometer-scale unstable icebergs. The transient contact force applied by the capsizing iceberg on the glacier…
A weakly non-hydrostatic shallow model for dry granular flows
José Garres-Díaz, Enrique D. Fernández-Nieto, Anne Mangeney +1
A non-hydrostatic depth-averaged model for dry granular flows is proposed, taking into account vertical acceleration. A variable friction coefficient based on the rheology i…
Multilayer models for shallow two-phase debris flows with dilatancy effects
José Garres-Díaz, François Bouchut, Enrique D. Fernández-Nieto +2
We present here a multilayer model for shallow grain-fluid mixtures with dilatancy effects. It can be seen as a generalization of the depth-averaged model presented in Bouchut et a…
Numerical approximation of the 3d hydrostatic Navier-Stokes system with free surface
S. Allgeyer, Marie-Odile Bristeau, D. Froger +5
In this paper we propose a stable and robust strategy to approximate the 3d incompressible hydrostatic Euler and Navier-Stokes systems with free surface. Compared to shallow water…
2D granular flows with the rheology and side walls friction: a well balanced multilayer discretization
E. D. Fernández-Nieto, J. Garres-Díaz, A. Mangeney +1
We present here numerical modelling of granular flows with the rheology in confined channels. The contribution is twofold: (i) a model to approximate the Navier-Stokes equat…
A multilayer shallow model for dry granular flows with the rheology: Application to granular collapse on erodible beds
Enrique D. Fernández-Nieto, José Garres-Díaz, Anne Mangeney +1
In this work we present a multilayer shallow model to approximate the Navier-Stokes equations with hydrostatic pressure and the -rheology. The main advantages of this approxi…
An energy-consistent depth-averaged Euler system: derivation and properties
Marie-Odile Bristeau, Anne Mangeney, Jacques Sainte-Marie +1
In this paper, we present an original derivation process of a non-hydrostatic shallow water-type model which aims at approximating the incompressible Euler and Navier-Stokes system…
Memory of the Unjamming Transition during Cyclic Tiltings of a Granular Pile
Stephanie Deboeuf, Olivier Dauchot, Lydie Staron +2
Discrete numerical simulations are performed to study the evolution of the micro-structure and the response of a granular packing during successive loading-unloading cycles, consis…
