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]).
The capillary force pumping fluid for self-pumping EGBC requires higher hydrophilic properties at the anode and cathode electrodes.
where [h.sub.c] is the height of capillary rise (m), [p.sub.c] is the capillary force expressed by the height of the water column (m), [I.sub.0] is the initial hydraulic gradient in a clay soil when bound water flows (dimensionless), D denotes the diameter of the soil particle fraction (mm), and [alpha] is a constant related to the temperature; if the temperature is 15[degrees]C, [alpha] is equal to 15 mm; if the temperature is 0[degrees] C, [alpha] is equal to 15.4 mm.
Colloidal nano-particle sorting and ordering on anodic alumina patterned surfaces using templated capillary force assembly.
It was also shown that lower injection rate produced a higher additional recovery after waterflooding and imbibition caused by injection rate which allowed capillary force to aid recovery accounted for this [29].
As depicted in Table 1, three [pi] terms represent the contribution of four forces (gravity force, driving force, capillary force, and viscous force) in the reservoir which influence the distribution of oil and water phases.
These forces were Capillary Force, [f.sub.capillary], (i.e., due to surface tension of the liquid), the Buoyancy, [f.sub.Buoyancy] due to difference in density of solid plate and density of liquid, Measured Force, [f.sub.measured], (he., tension force from the solid holder which is being measured by tensiometer force sensor) and the Gravity, [f.sub.gravity], (i.e., due to the weight of the solid plate).
By experimental studies of wettability on the photoelcectrode nanorod-array surface and oxygen bubble growth from anode, we analyzed the interaction affecting the gas-solid-liquid contact behaviors and product transportation mechanism, which is controlled by diffusion due to the concentration gradient of dissolved gases in the aqueous electrolyte and the microconvection caused by the bubble interface movement and we emphasize the importance of marangoni force due to nonhomogeneous gas adsorption at the interface and the capillary force caused by contact behavior with nanorod-array surface structure on bubble growth period.
This experiment confirms that only under the sway of capillary force can CNTs/epoxy dispersion processed with the sonication parameters used in this study infiltrate into the inter- and intra-bundle gaps.

Just like paper that sticks to table when it gets wet." The liquid surface tension between air, liquids and solids is called capillary force. In order to stick to dry surfaces insects use such capillary forces with the aid of their oil-covered adhesive setae instead of water.
A new, compact humidification system based on capillary force vaporizer (CFV) technology ensures optimal humidity and can be positioned next to the patient in the inspiratory limb to eliminate rainout.
To include the horizontal flow due to capillary force for three-dimensional infiltration from a disk infiltrometer, this formula has been modified as [3]:
There are also a number of published studies on long-range attractive interactions between like-charged micrometre-sized interfacial particles; the authors have argued that the capillary force or electrically induced capillary interactions are responsible for the particle ordering phenomenon at the liquid interfaces (Kralchevsky and Denkov, 2001; Earnshaw, 1986; Fernandez-Toledano et al., 2006; Foret and Wurger, 2004; Martinez-Lopez et al., 2000; Megens and Aizenberg, 2003; Nikolaides et al., 2002; Nikolaides, 2001; Stamou et al., 2000; Tata and Ise, 1998).
Stop strength also increased with hydrophilicity as did capillary force. Once fluid passed the stop, flow resumed.
