Numerical Study of Free-Surface Electrohydrodynamic Wave Turbulence [PDF]
IEEE Transactions on Dielectrics and Electrical Insulation (2023), 2023 Direct numerical simulation of threedimensional chaotic motion of a dielectric liquid with a free surface under the action of external horizontal electric field is carried out. The numerical model takes into account the effects of surface tension, viscosity, and external isotropic random forcing acting at large scales.

Ferrofluid Capillary Rise in Porous Medium under the Action of Non-Uniform Magnetic Field [PDF]
Journal of Fluids Engineering 2017, Vol. 139 / 011204, 2017 The capillary flow of a ferrofluid in a single cylindrical capillary tube and through a sandy porous medium under the action of a non-uniform magnetic field is studied experimentally. The dynamics of the capillary rise and the static case have been considered.

An Analytical and Numerical Study of Liquid Dynamics in a 1D Capillary under Entrapped Gas Action [PDF]
Math. Meth. Appl. Sci. 2014, 37 2923-2933, 2013 Capillary dynamics has been and is yet an important field of research, because of its very relevant role played as the core mechanism at the base of many applications. In this context, we are particularly interested in the liquid penetration inspection technique. Due to the obviously needed level of reliability involved with such a non-destructive test,

Gravity-capillary waves on the free surface of a liquid dielectric in a tangential electric field [PDF]
IEEE Transactions on Dielectrics and Electrical Insulation (2018), 2018 Processes of propagation and interaction of nonlinear gravity-capillary waves on the free surface of a deep non-conducting liquid with high dielectric constant under the action of a tangential electric field are numerically simulated. The computational method is based on the time-dependent conformal transformation of the region occupied by the fluid ...

Capillary Action Around Dental Structures [PDF]
Journal of Dental Research, 1973 The capillary action of saliva occurs in the crevices around and between teeth and around dental restorations. Marginal leakage and denture retention caused by a thin film of saliva are aspects of capillary phenomena. Liquids in capillaries isolated from a reservoir showed an increase in surface tension and lower vapor pressure.

Capillary Action in a Crack on the Surface of Asteroids with an Application to 433 Eros [PDF]
, 2016 Some asteroids contain water ice, and a space mission landing on an asteroid may take liquid to the surface of the asteroid. Gas pressure is very weak on the surface of asteroids. Here we consider the capillary action in a crack on the surface of irregular asteroids. The crack is modelled as a capillary which has a fixed radius. An asteroid s irregular

Nonequilibrium capillary self-assembly [PDF]
arXiv, 2023 Macroscopic objects supported by surface tension at the fluid interface can self-assemble through the action of capillary forces arising from interfacial deformations. The resulting self-assembled structures are ordered but remain trapped in one of potentially many metastable states in the capillary energy landscape.

Multiscale Poromechanics of Wet Cement Paste [PDF]
Proceedings of the National Academy of Sciences May 2019,
201901160, 2019 Capillary effects such as imbibition-drying cycles impact the mechanics of granular systems over time. A multiscale poromechanics framework was applied to cement paste, that is the most common building material, experiencing broad humidity variations over the lifetime of infrastructure.

Capillary Rise in Tubes with Sharp Grooves [PDF]
, 1994 Liquid in grooved capillaries, made by e.g. inserting a plate in a cylindrical tube, exhibits unusual spreading and flow properties. One example is capillary rise, where a long, upward tongue on top of the usual meniscus has been observed along the groove.
