Effects of small surface tension in Hele-Shaw multifinger dynamics: an analytical and numerical study [PDF]

open access: yes, 2002
We study the singular effects of vanishingly small surface tension on the dynamics of finger competition in the Saffman-Taylor problem, using the asymptotic techniques described in [S. Tanveer, Phil. Trans. R. Soc. Lond. A 343, 155 (1993)]and [M. Siegel,

Surface tension of steel at high temperatures

open access: yesSN Applied Sciences, 2023
Surface tension is a material property that is needed to describe fluid behaviour, which impacts industrial processes, in which molten material is created, such as thermal cutting, welding and Additive Manufacturing.

Influence of liquid surface tension (surfactants) on bubble formation at rigid and flexible orifices [PDF]

open access: yes, 2004
The influence of liquid surface tension on the bubble formation from both rigid and flexible orifice has been investigated. The liquid phases under test are aqueous solutions with butanol or surfactants (cationic, non-ionic and anionic); static and ...

The relationship between the surface tension and the saturated vapor pressure of model nanofluids

open access: yesHolodilʹnaâ Tehnika i Tehnologiâ, 2019
Information on surface tension is necessary for modeling boiling processes in nanofluids. It was shown that the problem of predicting the surface tension of complex thermodynamic systems, such as nanofluids, remains outstanding.

On surface tension for compact stars [PDF]

open access: yes, 2007
In an earlier treatment it was demonstrated that general relativity gives higher values of surface tension in strange stars with quark matter than neutron stars.We generate the modified Tolman-Oppenheimer-Volkoff equation to incorporate anisotropic ...

The Origin of Surface Tension

open access: yesInterPore Journal
In passing from the molecular description of matter to the continuum scale, many material properties and physical quantities emerge that do not exist at the molecular scale. They account for the way we observe lumped effects of molecular properties. So,

Surface tension of nanoparticle dispersions unravelled by size-dependent non-occupied sites free energy versus adsorption kinetics

open access: yesnpj Microgravity, 2022
The surface tension of dispersions presents many types of behaviours. Although some models, based on classical surface thermodynamics, allow partial interpretation, fundamental understanding is still lacking.

Influence of surface tension on two fluids shearing instability

open access: yes, 2014
Using extended Layzer's potential flow model, we investigate the effects of surface tension on the growth of the bubble and spike in combined Rayleigh-Taylor and Kelvin-Helmholtz instability.

Surface tension implementation for Gensmac 2D [PDF]

open access: yes, 2001
In the present work we describe a method which allows the incorporation of surface tension into the GENSMAC2D code. This is achieved on two scales. First on the scale of a cell, the surface tension effects are incorporated into the free surface boundary ...

Surface tension of surface-modified silica nanoparticles’ dispersions: The effect of temperature

open access: yesResults in Surfaces and Interfaces
This study examined the effect of temperature on the surface activity of surface-modified silica nanoparticles’ dispersions. Silica nanoparticles were functionalized with hydrophobic n-propyl, n-hexyl, or n-octyl groups, as well as hydrophilic methoxy ...
