Numerical modeling is a critical tool to the U.S. Department of Energy for evaluating the environmental impact of remediation strategies for subsurface legacy waste sites. Unfortunately, the physical and chemical complexity of many sites overwhelms the capabilities of even most state of the art groundwater models.

Global implicit solver for multiphase multicomponent flow in porous media with multiple gas components and general reactions [PDF]
Multiphase multicomponent flow processes in porous media have to be considered to study the efficiency of mineral trapping mechanisms for climate killing gas storage in deep layers. Robust predictions ask for the solution of large nonlinear coupled systems of diffusion-advection-reaction (partial differential) equations containing equilibrium reactions.

Materials Design and Assessment of Redox-Mediated Flow Cell Systems for Enhanced Energy Storage and Conversion. [PDF]
Redox‐mediated flow cells, which operate on an electrochemical‐chemical cycle, shift desired reactions from electrode compartments to dedicated reactors and enable diversified applications for high‐density flow batteries, fuel cells, CO2 capture, electrosynthesis, waste recycling, etc.

Multiphase flow and multicomponent reactive transport model of the ventilation experiment in Opalinus clay [PDF]
Abstract During the construction and operational phases of a high-level radioactive waste (HLW) repository constructed in a clay rock, ventilation of underground drifts will cause desaturation and oxidation of the rock. The ventilation experiment (VE) was performed in a 1.3 m diameter unlined horizontal microtunnel on Opalinus clay at Mont Terri ...

Numerical models of caldera deformation: Effects of multiphase and multicomponent hydrothermal fluid flow [PDF]
Ground surface displacement (GSD) in large calderas is often interpreted as resulting from magma intrusion at depth. Recent advances in geodetic measurements of GSD, notably interferometric synthetic aperture radar, reveal complex and multifaceted deformation patterns that often require complex source models to explain the observed GSD.

Upscaling multi-component two-phase flow in porous media with partitioning coefficient [PDF]
This paper deals with the upscaling of multicomponents two-phase flow in porous media. In this paper, chemical potential equilibrium at the interface between both phases is assumed to be described by a linear partitioning relationship such as Raoult or ...

Mesoscopic model for soft flowing systems with tunable viscosity ratio [PDF]
We propose a mesoscopic model of binary fluid mixtures with tunable viscosity ratio based on the two-range pseudo-potential lattice Boltzmann method, for the simulation of soft flowing systems. In addition to the short range repulsive interaction between
