Influence of the Reynolds number on non-Newtonian flow in thin porous media

Maria Anguiano, Matthieu Bonnivard, Francisco J. Suarez-Grau

We study the effect of the Reynolds number on the flow of a generalized Newtonian fluid through a thin porous medium in . This medium is a domain of thickness $\varep…

A generalized Reynolds equation for micropolar flows past a ribbed surface with nonzero boundary conditions

Matthieu Bonnivard, Igor Pažanin, Francisco J. Suárez-Grau

Inspired by the lubrication framework, in this paper we consider a micropolar fluid flow through a rough thin domain, whose thickness is considered as the small parameter $\varepsi…

Effective models for generalized Newtonian fluids through a thin porous medium following the Carreau law

Maria Anguiano, Matthieu Bonnivard, Francisco Javier Suarez-Grau

We consider the flow of a generalized Newtonian fluid through a thin porous medium of thickness , perforated by periodically distributed solid cylinders of size . We assume…

Modeling Carreau fluid flows through a very thin porous medium

María Anguiano, Matthieu Bonnivard, Francisco J. Suárez-Grau

This study investigates three-dimensional, steady-state, and non-Newtonian flows within a very thin porous medium (VTPM). The medium is modeled as a domain confined between two par…

A field-road system with a rectifiable set

Matthieu Bonnivard, Romain Ducasse, Antoine Lemenant +1

The aim of this paper is to define a field-road system in 2D where the road is a merely 1D-rectifiable set. For this purpose we introduce a general setting in order to define a par…

Phase field approximation for Plateau's problem: a curve geodesic distance penalty approach

Matthieu Bonnivard, Elie Bretin, Antoine Lemenant +1

This work focuses on a phase field approximation of Plateau's problem. Inspired by Reifenberg's point of view, we introduce a model that combines the Ambrosio-Torterelli energy wit…
