TL;DR: In this paper, a mechanism-based isotherm model was proposed to estimate the water vapor uptake at various relative humidities, which was well validated with the DVS data.

TL;DR: In this article, the authors examined the effects of ultrasound induced changes in coal pore/fracture and further measured gas permeability in coal by coupling the ultrasound field and external stress.

TL;DR: In this paper, a series of experiments were conducted to measure the gas adsorption and diffusion using the volumetric method and the Fick diffusion model was solved by both analytical method and numerical method to estimate the gas diffusion coefficient based on the experimental data.

TL;DR: In this article, a conceptualized cylindrical pore network was proposed to quantify the transient mass transfer in coal at various pressures, and experimental measurements were carried out to measure the time-dependent mass transfer through the volumetric method.

TL;DR: In this paper, a model for quantifying matrix shrinkage related effects including horizontal stress loss, vertical strain variation and permeability evolution was proposed, which was coupled into the poroelastic relationships to study the potential possibility of local failure.
