Flow velocity and momentum on wet beds are observed to increase significantly but slightly for dryer beds as a result of the pore-pressure feedback. These findings indicate that the debris composition of the catchment, the water content of bed sediment and the pore-pressure development should be...

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...
In shale formations with water under high temperature and pressure, CO2 dissolves and the solution is acidic, resulting in mineral dissolution and precipitation (Alemu et al., 2011; Carroll et al., 2011). However, reactive transport processes in oil gas reservoirs are complicated because fluid ...

The pressure inside the capillary (Pin) is lower than outside (Pout), and the surface of the liquid is bent downwards (Fig. 1). When the capillary is immersed into water as shown in Fig. 1, water is pulled inside and rises up to height h determined by the condition that the ...
3.1.2 Interfacial Pressure Discontinuity Model There may be zero, one or more interfaces in each link. Their positions along the link are contained in \(\mathbf {z}_{ij}\). Each element in \(\mathbf {z}_{ij}\) is thus between 0 and \(L_{ij}\). The symbol \(c_{ij}\) denot...
The meaning of each symbol in the figure is as follows: at least one “★” is a black point, “1” is a black point, “0” is a white point, and “♦” is a black or white point. Figure 3 Open in figure viewerPowerPoint Deletion templates along the U direction. “★,”“...

When all the alumina is used in one step the mixing time is simply represented by the symbol t. During this mixing period, the energy added to the system modifies the nature of the alumina particles and renders them extrudable and capable of bonding to themselves when subsequently formed ...
