Surface energy and surface tension of liquid metal nanodrops

EPJ Web of Conferences, 2011
A unitary approach has been proposed for the calculation of surface energy and surface tension of nanoparticle being in equilibrium with its saturated vapor on both flat and curved surfaces at given temperature.

Surface tension of steel at high temperatures

SN 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.

Surface tension implementation for Gensmac 2D [PDF]

, 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 ...

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

Holodilʹnaâ 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.

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

npj 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.

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

, 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,

The Origin of Surface Tension

InterPore 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,

Influence of Surface Tension on Dynamic Characteristics of Single Bubble in Free-Field Exposed to Ultrasound

Micromachines, 2022
The motion of bubbles in an ultrasonic field is a fundamental physical mechanism in most applications of acoustic cavitation. In these applications, surface-active solutes, which could lower the surface tension of the liquid, are always utilized to ...

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

Results 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 ...

A method for using surface tension to determine the size of holes in hardware [PDF]

, 1969
To check the size of small holes in injectors, flow control orifices, filters, and similar hardware, a surface tension technique is used. The liquid surface tension causes it to act as a membrane when pressure is applied.
