✦ Synopsis
A simple equation suitable for predicting the growth rate of a vapor bubble in uniformlysuperheated pure liquids and in binary solutions with a non-volatile solute was developed. The equation also improves on the popular pure-liquid bubble growth expression of Miki6 et al. (International Journal of Heat and Mass Transfer, 1992, 35, 1711-1722) in that it is valid throughout the bubble growth history, i.e. in the surface-tension-, inertia-, and heat-transfer-controlled regimes, it accounts for bubble growth acceleration effects, and uses correctly-related and variable fluid properties. It was found to agree very well with experiraental data for pure water and for aqueous NaCl solutions. As the bubble growth in superheated solutions with a non-volatile solute was found to be quite insensitive to diffusion and nonequilibrium effects in a broad range of common solution properties, this equation is likely to be universally valid for many liquids and solutions.
