ABSTRACT

We present the results of analysis of high-speed filming of the process of growth of vapor bubbles in superheated liquid. We show that secondary bubbles appear and grow on the surface of a primary bubble, so the primary bubble turns out to be surrounded by secondary ones. A model is suggested for the process of growth of secondary bubbles; in this model, the surface of the primary bubble is broken by local pressure of vapor output.
