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…

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…

Convergence to the Reynolds approximation with a double effect of roughness
Catherine Choquet, Laurent Chupin, Marguerite Gisclon
We prove that the lubrication approximation is perturbed by a non-regular roughness of the boundary. We show how the flow may be accelerated using adequate rugosity profiles on the…
