Capillary number was a dimensionless group describing the ratio of viscous to capillary forces [2-7].
The gravity force becomes the main driving force, which might not be large enough to overcome the capillary force in the reservoir.
The fuel was added to reservoir 1 and transported to reservoir 2 by capillary force. By the end, the fuel was transported to the flow field.
The CaBER is a filament-stretching device that monitors the diameter at the mid-point of a fluid filament as it thins under the action of capillary force. The uniqueness of the CaBER technique is to impose a premominantly uniaxial extensional step deformation on a fluid sample in order to extract information on its transient extensional properties.
During surfactant flooding lowering of the interfacial tensions helps recover additional oil by reducing the capillary force.
Brown (7) developed what is known as the capillary force hypothesis.
The capillary force, the buoyancy force of the immersed part and the hydrostatic pressure all contribute to the particle attachment at the gas/liquid interface, whilst the force of gravity, the capillary pressure and the additional external acceleration act to detach the particle.
Specifically this infiltration is that self-weight of eutectoid alloy-G, acting in same direction with capillary force:
Although Mountain Safety Research's stove is expected to be the first commercial application of capillary force vaporization, other projects are under way, according to Vapore's chief executive Robert Lerner, Possibilities range from fuel oil burners to the sophisticated Kerosene heaters that are popular in Japan, he said.
The capillary force acting at the channel opening resists the forward motion of the liquid--the "capillary barrier." When the centrifugal force is less than critical, the meniscus oscillates, but the oscillations eventually damp out and the meniscus returns to a steady state.
In Figure 2(b), both viscous and gravity forces are associated with H, while capillary force can drive flow in L direction.
