Abstract

The initial volume of a condensing bubble released from an orifice and the shape oscillations of the bubble during the collapse process were studied. Results of a large number of original experiments of bubbles condensing in miscible and immiscible liquids were analyzed to evaluate the initial volume, the instantaneous shape, and the average aspect-ratio of the bubbles. The results were compared to common empirical correlations that were originally developed to evaluate these parameters for noncondensing bubbles. It is demonstrated that such correlations can satisfactorily predict the initial volume of condensing bubbles and their mean aspect ratio throughout the collapse process.
