Saturated hydraulic conductivity of compacted bentonite–sand mixtures before and after gas migration in artificial seawater

open access: yesJournal of Rock Mechanics and Geotechnical Engineering, 2023
To understand the self-healing property of an engineered barrier for radioactive waste disposal, the hydraulic conductivity of compacted bentonite–sand mixtures saturated with artificial seawater (SW) before and after gas migration was examined.

Effect of Sorption Induced Swelling on Gas Transport in Coal [PDF]

open access: yes, 2018
In this study, an investigation of carbon dioxide sorption induced coal swelling and its effects on gas transport in coal is shown. The model presented is based on an existing coupled thermal, hydraulic, chemical and mechanical (THCM) model. A series of numerical simulations dealing with high pressure carbon dioxide injection in coal sample is ...

Simulation of dilatancy-controlled gas migration processes in saturated bentonite using a coupled multiphase flow and elastoplastic H2M model

open access: yesJournal of Rock Mechanics and Geotechnical Engineering, 2023
Dilatancy-controlled gas flow in preferential pathways plays a key role in the safety analysis of radioactive waste repositories. This is particularly the case for bentonite, an often-preferred barrier material.

Effects of fracturing fluid migration with clay damage after different shut-in period on shale gas production performance

open access: yesEnergy Reports, 2022
Shale gas wells may experience intentional shut in after fracturing operation partly because of the belief that soaking is beneficial. Although a number of numerical models have been built to analyze the fracturing fluid leak-off problems, neither of ...

Anisotropic Permeability Model for Coal Considering Stress Sensitivity, Matrix Anisotropic Internal Swelling/Shrinkage, and Gas Rarefaction Effects [PDF]

open access: yes, 2023
Permeability is the most crucial property of coal in relation to coalbed methane production and CO2 sequestration. Due to coal’s anisotropic structure and mechanical properties, its permeability exhibits strong anisotropy.

A new method for solving the fission gas diffusion equations with time-varying diffusion coefficient and source term considering recrystallization of fuel grains

open access: yesNuclear Materials and Energy, 2019
The fission gas swelling of nuclear fuels depends on the fission gas behavior in fuel grains, which will be accelerated by grain recrystallization occurred in some fuels.
