Theory of Subcooled Boiling
Subcooled boiling refers to boiling from a heated solid surface when the bulk liquid is below the saturation temperature. Particularly, when there is a bulk liquid flow past the surface, the heat fluxes thus sustained can be very large, in fact, subcooled boiling is the most efficient mode of cooling high-heat flux surfaces known, and as such is useful for cooling densely-packed computer microchips, as well as other applications, as in the heat treatment of metals. We have studied several aspects of subcooled boiling from a fundamental aspect, leading, among other things, to a resolution of a long-standing question as to the dominant mechanism of subcooled boiling: vapor transport through an ultrathin layer liquid underneath the growing bubble or stirring of the liquid surrounding the growing-and collapsing bubble.
