A shallow water model for the numerical simulation of overland flow on surfaces with ridges and furrows (2009)

Razafison, Ulrich, Cordier, Stephane, Delestre, Olivier, Darboux, Frédéric, Lucas, Carine, James, Francois

We introduce here a shallow water model for the numerical simulation of overland flow with furrows effects without representing them explicitly. The model is obtained by adding to the classical...

Mathematical Modelling and Numerical Analysis Will be set by the publisher Modelisation Mathematique et Analyse Numerique DIFFUSION LIMIT OF THE LORENTZ MODEL: ASYMPTOTIC PRESERVING SCHEMES (2007)

Christophe Buet, Stephane Cordier, B. Lucquin-desreux, S. Mancini

Abstract. This paper deals with the diusion limit of a kinetic equation where the collisions are modeled by a Lorentz type operator. The main aim is to construct a discrete scheme to approximate this...

On regularized Boltzmann operators (2007)

Christophe Buet, Stephane Cordier

In this paper, we propose two regularization approaches for the Boltzmann collision operator. The constructed operators preserve the mass, momentum and energy; their equilibrium states are...

Shadowing effects for continuum and discrete deposition models (2006)

Thi, Thu Huong Vo, Brault, Pascal, Rouet, Jean-Louis, Cordier, Stephane

We study the dynamical evolution of the deposition interface using both discrete and continuous models for which shadowing effects are important. We explain why continuous and discrete models...

On a kinetic model for a simple market economy (2004)

Cordier, Stephane, Pareschi, Lorenzo, Toscani, Giuseppe

In this paper, we consider a simple kinetic model of economy involving both exchanges between agents and speculative trading. We show that the kinetic model admits non trivial quasi-stationary states...

Hyperbolicity of the hydrodynamic model of plasmas under the Quasineutrality hypothesis (1995)

Stephane Cordier

: Collisionless, quasineutral and near-equilibrium hydrodynamic model of plasmas consisting of electrons and several species of ions are investigated. When two species of ions are considered, the...

Hyperbolicity of Grad's extension of hydrodynamic models for ionospheric plasma. Part 2: The two-species case (1993)

Stephane Cordier

: We investigate the hyperbolicity of the 5, 8, 10, 13 and 16moment Grad systems for two species of particles under the quasineutrality hypothesis. The analysis is based on an asymptotic expansion...

Hyperbolicity of Grad's extension of hydrodynamic models for ionospheric plasma. Part 1: The single species case.

Stephane Cordier

: We present the fluid equations derived by Schunck following Grad's approach to solve the Boltzmann equation for near maxwellian distribution functions. We study the hyperbolic part of these...
