The data of video filming of the behavior of air bubbles near the heating surface during boiling of subcooled water are presented. The effects the regime parameters (heat flow rate and water subcooling relative to the saturation temperature) have on

Under boiling of highly subcooled water at high heat flow rates, several authors have observed emission of numerous small (10–80 μm) bubbles. This phenomenon has been called as “microbubble emission.” In this paper we make an attempt to explai
