Surface tension is defined as the work required to increase the area of a surface isothermally and reversibly by unit amount. It is expressed as surface energy per unit area and alternatively as force per unit length. The work of adhesion is defined as the reversible thermodynamic work that is...
One of the limitations of the model98is the fact that the meansurface tension gradientτ¯is being imposed as a boundary condition instead of being correlated with the mass flow of tensioactive vapor to the surface. BecauseH(Ma) is a monotonously decreasing function, there is a one-to-one...
This term became so entrenched in the literature that it is widely used today. Thus γ is widely called the surface tension, though the meaning of those words may have little physical significance in many situations. As mentioned above, the quantity γ is the scalar thermodynamic surface energy...
With the loading of intrinsic surface stress, nanofilms should bend or expand (or shrink). The equilibrium strain and bending curvature showed size dependent. The surface stress acts on a nanofilm surface, the effect is similar to a pre-tensional adhesive tape on top and bottom surfaces of th...
Surface Tension as a Motivation for Sintering 来自 Springer 喜欢 0 阅读量: 154 作者: C Herring 摘要: The sintering together of powder particles into a dense solid mass at temperatures below the melting point of the particles is a process whose rate and end result are known to be influenced ...
Summarily, an improved 3D heat and mass transfer model is developed here to study the roles of driving force, surface tension-driven flow and their correlation with concentration dilution. Novelties for this study could be summarized as follows. Contributions to the developed numerical model and anal...

Silicone and fluorinated polymers or oligomers are the most used surface-active additives for the reduction in surface tension and wettability and increased dry lubricity of both thermoplastic and thermoset matrices. 10.6.1.3 Amphiphilic Coatings Amphiphilic polymers contain both hydrophilic and hydrophobic ...
