Abstract
Gas bubbles migrating under the influence of a temperature gradient in KCl gradually evolve stable shapes which have a low length (in the direction of migration) to width ratio and are bounded by cube planes (100). The shape is determined by evaporation-condensation kinetics and not by the equilibrium surface energies. A significant part of the bubble volume is left behind in a trail of very fine bubbles resulting in as much as a fivefold increase in bubble surface area. Most of the observed phenomena can be correlated with the detailed temperature distribution around a migrating bubble.This publication has 6 references indexed in Scilit:
