Non-isochoric stable granular models taking into account fluidisation by pore gas pressure
Laurent Chupin, Thierry Dubois
In this paper, we study non-isochoric models for mixtures of solid particles, at high volume concentration, and a gas. One of the motivations of this work concerns geophysics and m…
Variational inequality solutions and finite stopping time for a class of shear-thinning flows
Laurent Chupin, Nicolae Cîndea, Geoffrey Lacour
The aim of this paper is to study the existence of a finite stopping time for solutions in the form of variational inequality to fluid flows following a power law (or Ostwald-DeWae…
Global strong solutions for some differential viscoelastic models
Laurent Chupin
The purpose of this article is to show that there are many differential viscoelastic models for which the global existence of a regular solution is possible. Although the problem o…
A bi-projection method for incompressible Bingham flows with variable density, viscosity and yield stress
Rénald Chalayer, Laurent Chupin, Thierry Dubois
A new numerical scheme for solving incompressible Bingham flows with variable density, plastic viscosity and yield stress is proposed. The mathematical and computational difficulti…
Existence theorem for homogeneous incompressible Navier-Stokes equation with variable rheology
Laurent Chupin, Jordane Mathé
We look at a homogeneous incompressible fluid with a time and space variable rheology of Bingham type, which is governed by a coupling equation. Such a system is a simplified model…
Viscoelastic Flows In A Rough Channel: A Multiscale Analysis
Laurent Chupin, Sébastien Martin
In this paper, we consider viscoelastic flows in a rough domain (with typical roughness patterns of size < 1). We present and rigorously justify an asymptotic expansion with re…
