Growth of single bubbles in a uniformly superheated binary solution containing a non-volatile solute was studied both experimentally, using an aqueous solution of NaCl at mass fractions of 0.05 and 0.20, an initial temperature range of 40-80-degrees-C and an applied initial superheat range of 1.7-16.5-degrees-C, and theoretically, with very good agreement between the experimental and theoretical results. The experimental technique developed, using an electrolytically nucleated bubble, was found to be excellent for single-bubble growth studies and photography. Some of the principal conclusions are that increasing the concentration of the non-volatile solute at a given initial solution temperature reduces the bubble growth rate when the far-field pressure is dropped to a fixed value. The effect of concentration on the bubble growth rate becomes smaller when the far-field pressure is reduced to bring the solution to either a fixed superheat, or to a fixed initial pressure difference between the bubble interior and exterior, leading to a conclusion that it is preferable to study and correlate bubble growth rates by using the superheat and this pressure difference as parameters.
