Experimental techniques for studying interfacial dynamics and sediment response during CH₄-CO₂ hydrate replacement [PDF]

open access: yes
Methane hydrates are a largely untapped energy resource with the potential to support carbon sequestration through CH₄-CO₂ exchange. However, large-scale methane recovery from hydrate-bearing sediments remains constrained by key uncertainties related to ...

Influence of Capillarity on Nano-Liter Flowrate Measuremet with Displacemet Method

open access: yes, 2007
Nano-liter flowrate measurements in micro-tubes with displacement method were performed and the effect of capillarity force on the accuracy was investigated through lab experiments and theoretical analysis in this article.

Numerical modeling of unsaturated flow in porous media using a thermodynamical approach [PDF]

open access: yes
The Richards equation has been widely used to describe unsaturated flow in porous media, but its thermodynamical consistency has been scarcely investigated.

Lax-Friedrichs and the Viscosity-Capillarity Criterion

open access: yes, 1983
It has been shown by Lax some time ago that for hyperbolic conversation laws solutions obtained as limits of the Lax-Friedrichs finite difference scheme will actually satisfy an "entropy" admissibility criterion.

Effects of gravity and buoyancy on spontaneous liquid-liquid imbibition in fractured porous media [PDF]

open access: yes
Spontaneous imbibition in porous materials has received significant attention in recent decades; however, spontaneous liquid-liquid imbibition in fractures has not been well studied.

Effects of salinity and driving pressure on water imbibition during shale formation [PDF]

open access: yes
During the construction stage of underground engineering projects, the engineering fluids used often carry a certain level of pressure, and rock formations in the subsurface invariably contain fluids with a certain degree of salinity.

Theoretical and experimental analysis of surface anchoring in the surface stabilization of ferroelectric liquid crystal cells [PDF]

open access: yes
Based on the response of a chiral smectic liquid crystal to electrical excitation, this paper develops a theoretical calculation to explain the observed phenomenon in a confined structure, with the aim to establish a connection between these phenomena ...
