A two-dimensional unsteady seepage model for coal using a finite element program is developed, and the temporal variations of key factors such as water pressure and hydraulic gradient are analyzed in this paper. Additionally, the triaxial rock mechanical experiment and utilized pneumatic fracturing equi...
The surface tension of the liquid/gas interface in a curved capillary causes lower liquid water activity,aw,c, and lower partial pressure of vapor,p, at the curved surface, than corresponding values in the solution (of the same salinity) with flat surface. The difference in the water chemical...
aS. R. Lee, Y. K. Kim, J. Y. Choi The value of matric suction at the wetting front ψ is not zero because a little amount of air exists in the pore of the nearly saturated soil. Therefore the wetting front exhibits some negative pore water pressure (matric s 正在翻译,请等待...[...
As expected, the displacement at θw = 30°, which is a drainage process, where the non-wetting phase (air) displaces the wetting phase (water), shows the highest pressure drop across the medium among all three cases (Fig. 6). The lowest pressure drop is for the imbibition process...

pressure-molding the mixture to obtain a molded body, and firing the molded body; then bringing the porous body into contact with an aqueous alkali solution; bringing the porous body into contact with water until the alkali concentration of the porous body becomes 0.3 at % or less; and subseq...
The high thermal diffusivity and small size of the sample (≈100 μm) ensure that its temperature and hence the water pressure closely track their target values. This work uses methane-saturated water, but study of e.g. brines would be relevant to gas hydrates. Fortunately, the values of...
10. b Immunohistological staining for α-SMA (red), cell nuclei (blue), and autofluorescence (AF) signal (green) at the interface between cartilage (group A, hash symbol) or mineralized tissue (groups R,B,E, asterisk) and non-mineralized tissue. Boxplot shows quantification of α-SMA-...
Hydrates, as solid materials, change the original pore water distribution and connectivity, which causes a significant change of resistivity [8]. When hydrates exist in the throat of the pores, blocking the electrical conductive path, the resistivity of hydrate-bearing sediments will increase ...
Here, we investigate the capacity of a graphene slit-pore to sequester methanol from a water–methanol mixture and its effects on the mixture. In particular, we study how different water–methanol mixture properties—such as density, pressure, and composition—are affected as the width 𝛿δ of...
