The experimental insights gained have, in turn, strongly stimulated further theoretical and mathematical investigations. Advancing and receding contact angles, wetting barriers, pinning of contact lines, oscillations of capillary surfaces and fluid sloshing are also discussed.

In fluid mechanics and Capillary surfaces book, a capillary surface is a surface that represents the interface between two different a consequence of being a surface, a capillary surface has no thickness in slight contrast with most real fluid interfaces.

Capillary surfaces are of interest in mathematics because the problems involved are very nonlinear and have interesting properties, such as.

Some details can be found in Langbein's book. Radial graphs and capillary surfaces in a cone are examples analogous to (vertical) graphs on a plane and capillary surfaces in a vertical cylinder if we move the vertex O of the cone to infinity. For a convex cone C Γ, Choe and Park have shown that if a parametric capillary surface S meets C Γ orthogonally, then S is part of a sphere [8].Cited by: 6.

Capillary forces can have a critical impact at the microscale. Capillary forces act at fluid-air-solid interfaces to minimize the surface energy of the interface. Surface tension or capillary forces scale with the perimeter of the wetted area ~[s 1].In the bulk region of a liquid, cohesive forces between the liquid molecules are balanced and shared with all the neighboring molecules.

History. Capillary bridges have been studied for over years. The question was raised for the first time by Josef Louis Lagrange inand interest was further spread by the French astronomer and mathematician C. Delaunay. Delaunay found an entirely new class of axially symmetrical surfaces of constant mean formulation and the proof of his theorem had a long story.

Some mathematical aspects of capillary surfaces A. Mellet∗ April 9, Abstract This is a review of various mathematical aspects of the study of cap-illary surfaces. A special emphasis is put on the behavior of the contact line, the three phases junction between the liquid, solid and vapor.

1 Introduction. Get this from a library. Capillary surfaces: shape-stability-dynamics, in particular under weightlessness. [Dieter W Langbein] -- This book is devoted to interfaces between two fluids, that is, between a liquid and a gas (such as water and air) or between two liquids (such as water and oil).

The main motivation for the book. ISBN: OCLC Number: Description: XIII, Seiten: Diagramme. Contents: 1 Introduction.- An interface constitutes an extensive, two‐dimensional defect in a system.

This chapter is devoted to interfaces between a pure liquid and its vapor. The interface is characterized by easy mechanical. Capillary action occurs because water is sticky, thanks to the forces of cohesion (water molecules like to stay close together) and adhesion (water molecules are attracted and stick to other substances).

Adhesion of water to the walls of a vessel will cause an upward force on the liquid at the edges and result in a meniscus which turns upward. Although surface tension is present at all interfaces, it is most important for small fluid bodies. At length scales where surface tension does come into play the shape of an inter-face bears little relation to the gravitational equipotential surfaces that dominate the static shapes of large-scale systems analyzed in the preceding Size: KB.

This classification produces a unified approach to fluid interfaces in capillary tubes, sessile and pendent drops, liquid bridges, as well as exterior and annular capillary surfaces. Capillary surfaces are closely related to minimal surfaces.

In fact, capillary surfaces minimize a more general functional than do minimal surfaces. The standard mathematical model for volume constrained capillary problems is as follows: a set in is the region occupied by.
