Subsequently, buoyant CO2 may be more securely trapped by dissolving CO2 into water (carbonated water is more dense than non-carbonated water and will sink), or by capillary forces acting to hold the CO2 in the small confines of the pore space.
When the wetting liquid imbibes in the pore of the tight core, it will be subjected to capillary forces ([P.sub.ca]), the hydrostatic pressure ([P.sub.ha]), and the resistance of porous flow ([P.sub.Ga]).
Within the CDZ, fluid interfaces and hydraulically reservoir-disconnected WP clusters are subject to the interplay of viscous and capillary forces. This is discussed in terms of the temporal evolution of mean pressure profiles [bar.p]([X.sub.1], t) (Figure 6(b)).
This in turn reduces the adhesion forces between particles and the substrate causing the meniscus capillary forces to effectively remove the largest diamond crystals from the PAAO membrane with a net force [F.sub.R].
Capillary forces between the small particles make the resulting structure very dense and give it a slightly shrunken component that is essentially full density with tensile and hardness properties equivalent to handbook values.
Smaller mammals are challenged during urination by high viscous and capillary forces that limit their urine to single drops.
The author covers the surface chemistry and geochemistry of hydraulic fracturing, capillary forces in fluid flow in porous solids, surface active and fracture-forming substances, and a wide variety of other related subjects over the course of the bookAEs eight chapters.
Capillary number was a dimensionless group describing the ratio of viscous to capillary forces [2-7].
This effect is caused by the capillary forces between the liquid molecules and the solid surface.
These microscopic cavities induce capillary forces that keep sanitizers outside the concave areas.
"These coating essentially act like a sponge, when a vapor bubble forms on the surface they wick liquid underneath it using capillary forces to delay the dry-out phenomena associated with critical heat flux.
The coatings are custom-made for each application by combining a porous solid with a liquid that gets trapped within it via strong capillary forces. They can be made from edible ingredients, making them safe for foods, health and beauty products and other consumer goods.
