Capillary Action in Impregnated Paper Insulation
Physics, 1932The capillary rise of oil in vertical strips of impregnated paper obeys the same law as the rise of liquids in capillary tubes of circular cross section. From the viscosity and surface tension of an oil and its rate of rise in a given paper, it is possible to compute the ``effective capillary radius'' of the capillary pores of the paper.

An Ising-Based Simulator for Capillary Action in Porous Media
Transport in Porous Media, 2018Multiphase flows in porous media are encountered in several contexts—e.g., hydrocarbon recovery operations, battery electrodes, microfluidic devices, etc. Capillary-dominated flows are interesting due to the complex interplay of interfacial properties and pore geometries.

On the action of capillary pressure in fresh concrete
Cement and Concrete Research, 1976Abstract Capillary pressure and plastic shrinkage have been measured simultaneously. The action of capillary pressure in fresh concrete is assumed to be the cause of plastic shrinkage. Characteristic results are presented to verify the essential statements of this hypothesis.

Two Contrasting Theories of Capillary Action
American Journal of Physics, 1959Two theories regarding the mechanism of the rise of a liquid in a capillary tube appear in current textbooks of physics and physical chemistry. In one theory the rise is attributed to hydrostatic pressure; in the other, the liquid is drawn up the tube by a climbing meniscus. Evidence is presented in favor of the latter theory.

Interface Motion Driven by Capillary Action in Microchannel
1st International Conference on Microchannels and Minichannels, 2003In microchannel flow, gas-liquid interface behavior will be important for developing a wide range of microfluidic applications, especially in micro reactors. In this paper, we discuss some topics related to capillary action and two-phase fluid behavior in a microchannel. One of the topics is interface motion in the flow driven only by capillary action.

The mechanism of action and place of application of capillary forces
Colloid Journal, 2017The question of the mechanism of action and the place of application of capillary forces has been discussed. It has been shown that the conventional notions of the character of capillary forces are often contradictory. A molecular-kinetic approach has been employed to determine the places of application of capillary forces and the mechanism of their ...

Drying shrinkage of concrete due to capillary action [PDF]
Matériaux et Constructions, 1969 The effect of capillary tension on drying shrinkage of cement paste and concrete is explained. The theory is based on principles of thermo-dynamics and theory of elasticity.

1. Remarks on the Theories of Capillary Action
Proceedings of the Royal Society of Edinburgh, 1872That theory of capillary action, which seems to have satisfied the greater number of physicists, is founded on the assumption that the particles of a fluid are separated by distances immensely great in comparison with their magnitudes, and that these particles attract each other,—the sphere, however, of their attraction extending to a distance ...

The Use of Capillary Action Measurements for Solderability Improvement
Soldering & Surface Mount Technology, 1991This paper describes the tests performed to evaluate the solder capillary action which occurs within a gap between two solderable surfaces during soldering. The goal was to determine the optimal gap distance for maximum capillary flow in the attainment of hermetic solder joints capable of withstanding extreme temperature cycles and various mechanical ...

Motion of a gas inclusion in a capillary under the action of vibration
Fluid Dynamics, 1998The motion of gas inclusions in a liquid-filled duct under the action of vibration for comparable cross-sectional dimensions of the inclusion and the duct is studied. Two limiting cases of inclusion motion differing with respect to the drag mechanism are considered.
