Bubble Collapse in Subcooled Boiling

Abstract

The motion of a vapor bubble in subcooled boiling was studied experimentally using slightly subcooled water, ethanol, and carbon-tetrachloride under the atmospheric pressure. The degree of subcooling ranged usually from about 2°C to 50°C, and in a few extreme cases it was extended to below 1°C. The experimental data for the collapse stage were found to be well correlated by the equations which were derived by assuming a laminar heat trasfrer between the spherical bubble and the surrounding liquid with uniform subcoolings.
