Equivalence between volume averaging and moments matching techniques for mass transport models in porous media. [PDF]

open access: yes, 2010
This paper deals with local non-equilibrium models for mass transport in dual-phase and dual-region porous media. The first contribution of this study is to formally prove that the time-asymptotic moments matching method applied to two-equation models is

La notion de grandeur et la légitimité de la mathématisation en physique [PDF]

open access: yes, 2001
Newton's use of mathematics in mechanics was justified by him from his neo-platonician conception of the physical world that was going along with his «absolute, true and mathematical concepts» such as space, time, motion, force, etc.

Fully coupled simulations of monodisperse and bidisperse suspensions in a linear shear flow [PDF]

open access: yes, 2006
The dynamics of macroscopically homogenous sheared suspensions of neutrally buoyant, non-Brownian spheres is investigated in the limit of very small Reynolds and Stokes numbers using the Force Coupling Model (Lomholt & Maxey1). In this numerical approach,

Modeling and simulation of inertial drop break-up in a turbulent pipe flow downstream of a restriction. [PDF]

open access: yes, 2012
This work deals with the modeling of drop break-up in an inhomogeneous turbulent flow that develops downstream of a concentric restriction in a pipe. The proposed approach consists in coupling Euler–Lagrange simulations of the drop motion to an interface

Experimental and CFD Analysis of a Solar Air Heater Integrated with Ribs Filled with PCM Materials: Drying applications

open access: yesRevue des Énergies Renouvelables
The major challenge of renewable energies, including solar, is their intermittent nature. Therefore, the issue of energy storage becomes crucial to meet demand when the main source is not available.

Les recherches actuelles sur d'Alembert: A propos de l'édition de ses Oeuvres complètes [PDF]

open access: yes, 2002
La concrétisation du projet de publication des Oeuvres complètes de Jean le Rond d'Alembert (1717-1783), Géomètre et Philosophe, redonne une actualité aux recherches sur cet auteur dont l'importance est fondamentale dans de nombreux domaines de l ...
