The DFLU flux for systems of conservation laws
Adi Adimurthi, G. D. Veerappa Gowda, Jérôme Jaffré
The DFLU numerical flux was introduced in order to solve hyperbolic scalar conservation laws with a flux function discontinuous in space. We show how this flux can be used to solve…
Space-Time Domain Decomposition Methods for Diffusion Problems in Mixed Formulations
Thi Thao Phuong Hoang, Jérôme Jaffré, Caroline Japhet +2
This paper is concerned with global-in-time, nonoverlapping domain decomposition methods for the mixed formulation of the diffusion problem. Two approaches are considered: one uses…
Gas phase appearance and disappearance as a problem with complementarity constraints
Ibtihel Ben Gharbia, Jérôme Jaffré
The modeling of migration of hydrogen produced by the corrosion of the nuclear waste packages in an underground storage including the dissolution of hydrogen involves a set of nonl…
Applications of the DFLU flux to systems of conservation laws
Adimurthi Adimurthi, G. D. Veerappa Gowda, Jérôme Jaffré
The DFLU numerical flux was introduced in order to solve hyperbolic scalar conservation laws with a flux function discontinuous in space. We show how this flux can be used to solve…
Estimating nonlinearities in twophase flow in porous media
Jianfeng Zhang, Guy Chavent, Jérôme Jaffré
In order to analyze numerically inverse problems several techniques based on linear and nonlinear stability analysis are presented. These techniques are illustrated on the problem…
Henry's law and gas phase disappearance
Jérôme Jaffré, Amel Sboui
For a two-phase (liquid-gas) two-component (water-hydrogen) system in porous media we discuss the formulation of the possible dissolution of hydrogen in the liquid phase. We show h…
