A two-phase mixture model of liquid-gas flow and heat transfer in capillary porous media—I. Formulation
TL;DR: In this article, a model for two-phase transport in capillary porous media is presented, in which the two phases are viewed as constituents of a binary mixture, and conservation equations are derived from the classical separate flow model without invoking additional assumptions.

On thermohydrologic conditions near high‐level nuclear wastes emplaced in partially saturated fractured tuff: 1. Simulation studies with explicit consideration of fracture effects
TL;DR: In this paper, the authors have performed modeling studies on the simultaneous transport of heat, liquid water, vapor, and air in partially saturated, fractured porous rock, and found that a substantial fraction of waste heat can be removed if emplacement holes are left open and ventilated, as opposed to backfilled and sealed conditions.

Theory of multiple bubble growth in porous media by solute diffusion
X. Li,Yannis C. Yortsos +1 more
TL;DR: In this paper, a theoretical analysis of bubble growth in porous media by solute diffusion is presented based on visualization experiments, and the effect of (heterogeneous) nucleation on the growth of multiple clusters is analyzed.

A two-phase mixture model of liquid-gas flow and heat transfer in capillary porous media—II. Application to pressure-driven boiling flow adjacent to a vertical heated plate
TL;DR: In this article, a two-phase mixture model is applied to investigate a pressure-driven two-phased boiling flow along a heated surface embedded in a porous medium. But the model is restricted to a single phase and the boundary layer equations for the two phases are solved by a similarity transformation.

A similarity solution for two-phase fluid and heat flow near high-level nuclear waste packages emplaced in porous media
Christine Doughty,Karsten Pruess +1 more
TL;DR: In this paper, the partial differential equations governing fluid and heat flows in a radial geometry can be converted to ordinary differential equations by using a similarity variable, ν = r/√t.

A closed-form equation for predicting the hydraulic conductivity of unsaturated soils
van Genuchten,M. Th. +1 more
TL;DR: Van Genuchten et al. as mentioned in this paper proposed a closed-form analytical expression for predicting the hydraulic conductivity of unsaturated soils based on the Mualem theory, which can be used to predict the unsaturated hydraulic flow and mass transport in unsaturated zone.

Heat transfer in porous media considering phase change and capillarity—the heat pipe effect
TL;DR: In this paper, a steady state analysis of the heat and mass transfer in porous media saturated with the liquid and vapor phases of a single component fluid was conducted, and the effects of capillarity, gravity forces, and phase change were included.

TOUGH User's Guide
TL;DR: Tough as discussed by the authors is a computer program developed at the Lawrence Berkeley Laboratory for simulating the coupled transport of water, vapor, air and heat in porous and fractured media, where the physical processes taken into account in TOUGH are discussed, and the governing equations actually solved by the simulator are stated in full detail.
