Charge transfer between colliding hydrometeors: Role of surface tension gradients

The influence of surface tension gradients on drop coalescence

We present the results of a combined experimental and numerical investigation of the coalescence of a drop with a liquid reservoir of a miscible but distinct fluid. Particular attention is given to elucidating the influence on the coalescence process of a surface tension difference between drop and reservoir. Drops are gently deposited on the surface of the reservoir, and so coalesce with negli...

Role of Surface Tension Gradients in Correcting Coating Defects in Corners

normally has an uneven surface. When surface tension can Following the application of a liquid coating to a curved subbe considered to be uniform, capillary forces tend to reduce strate, surface tension forces will act to redistribute the coating surface irregularities to produce a level film. This is the layer. The coating will thin at outside corners and thicken at dominant effect leading to ...

Dependence of surface stress, surface energy and surface tension on potential and charge.

A toy model and simple model functions are used to exemplify the relation between surface tension, surface energy and surface stress given by Shuttleworth's equation. Variations of the surface tension of charged interfaces must obey Lippmann's equation. Variations Deltaf of the surface stress of electrodes would be either equal to or proportional to and smaller than those variations Deltagamma ...

The Role of Surface Tension for the Equation of State of Surface Tension Quark-Gluon Bags

The temperature and chemical potential dependent surface tension of bags is introduced into the gas of quark-gluon bags model. The suggested model is solved analytically. It resolves a long standing problem of a unified description of the first and second order phase transition with the cross-over. Such an approach is necessary to model the complicated properties of quark-gluon plasma and hadro...
