Abstract

Incipient nucleate pool boiling and strong bubble-bubble interactions feature dramatic heat transfer enhancements associated with liquid vaporization. We employ numerical methods to show that very high heat transfer towards the bubble-heating surface contact line is the likely mechanism in the former case. To study these phenomena, we employ a boundary element method together with an asymptotic expansion of the contact line region in order to determine the quasistatic temperature field around a spherical vapor bubble on or near a solid-liquid interface in a periodic cell. Both the heating solid and the liquid layer are of finite depth perpendicular to their mutual interface and one may arbitrarily prescribe far field temperatures or heat fluxes. Narrow cell wi
