โœฆ Synopsis

A vapour bubble at a liquid-solid interface in a binary mixture grows without changing its shape, its dimensions increase proportionally with the square root of the growth time. This growth process, controlled by the transport of heat and matter, is described by a self-similar solution.

Analysis shows the reduction in growth rate, relative to a pure liquid, to be the same to a first approximation as the reduction for a free spherical bubble.

The dry area in the microlayer under the bubble can be much smaller in a binary mixture than in a pure liquid, and this will influence the peak heat flux which can be attained in nucleate boiling.
