Multilayer shallow water models with locally variable number of layers and semi-implicit time discretization
(Elsevier Inc., 2018)
We propose an extension of the discretization approaches for multilayer shallow water models, aimed at making them more flexible and efficient for realistic applications to coastal flows. A novel discretization approach ...

A well-balanced finite volume-augmented lagrangian method for an integrated Herschel-Bulkley model
(Plenum Press, 2012)
We are interested in the derivation of an integrated Herschel-Bulkley model for shallow flows, as well as in the design of a numerical algorithm to solve the resulting equations. The goal is to simulate the evolution of ...

A second order pvm flux limiter method. Application to magnetohydrodynamics and shallow stratified flows
(Academic Press, 2014)
In this work we propose a second order flux limiter finite volume method, named PVM-2U-FL, that only uses information of the two external waves of the hyperbolic system. This method could be seen as a natural extension of ...

A multilayer shallow model for dry granular ows with the (I)-rheology: application to granular collapse on erodible beds
(Cambridge University Press, 2016)
In this work we present a multilayer shallow model to approximate the Navier–Stokes equations with the μ(I)μ(I)-rheology through an asymptotic analysis. The main advantages of this approximation are (i) the low cost ...

A two-phase shallow debris flow model with energy balance
(2015)
This paper proposes a thin layer depth-averaged two-phase model provided by a dissipative energy balance to describe avalanches of solid-fluid mixtures. This model is derived from a 3D two-phase model based on the equations ...

Thermal 3D CFD Simulation with Active Transparent Façade in Buildings
(MDPI, 2018-08-28)
In recent years active façades have acquired greater importance given their capacity to improve the energy efficiency of buildings. One such type is the so-called Active Transparent Façade (ATF). A 3D numerical model based ...

Two shallow-water type models for viscoelastic flows from kinetic theory for polymers solutions
(Dunod, 2013)
In this work, depending on the relation between the Deborah, the Reynolds and the aspect ratio numbers, we formally derived shallow-water type systems starting from a micro-macro description for non-Newtonian fluids in a ...

A two-phase solid-fluid model for dense granular flows including dilatancy effects: comparison with submarine granular collapse experiments
(2017)
We simulate here the collapse of granular columns immersed in a viscous fluid based on a simplified version of the model developed by [2]. The simulation quite well reproduces the dynamics and deposit of the granular ...

Dilatancy in dry granular flows with a compressible μ(I) rheology
(Elsevier, 2021)
Dilatancy plays a key role in mixtures of grains and fluid but is poorly investigated in dry granular flows. These flows may however dilate by more than 10% in granular column collapses. We investigate here dilatancy effects ...
