Abstract

Existing models for the equilibrium of a bubble at a heated surface are discussed; an alternative model is presented, based on conduction as the dominant mechanism in the liquid and on vapour transfer within the bubble. No artificial restrictions are made at the boundaries and the only condition to be fulfilled by the mathematical solution is continuity of temperature and heat flux at the liquid-vapour, liquid-solid, and vapour-solid interfaces. The characteristic distance in the undisturbed liquid, at which the liquid and the vapour temperatures are identical, is determined as a function of dimensionless parameters which contain the physical properties of fluid and wall material in addition to nucleation cavity size.
