Transferts complexes en milieu poreux :
Quelques approches physiques et numériques

Abstract : The feasibility and safety of nuclear waste storage containers is studied.

The thermodynamics of water/air flow is described and applied, via a simplified numerical model, to a simple experimental apparatus yielding heat pipe effect.

The 2D influence of deterministic boundary conditions is important on kinematics and transport. Dispersivity depends on the nonuniform flow type and integrates the often marginal gaussian part of plume spreading.

A new algorithm, based on jump locality and recalibration, avoids the small biais induced by inter-cell diffusive jumps.

Several algorithms modeling transport of decaying, soluble, sorbing, or precipitating species are compared. Stability and precision criteria are analyzed. Up-stream over-precipitation and negative down-stream concentrations are observed for high solubility contrasts.
