The paper presents the results of an experimental study of the dynamics of boiling of a subcooled liquid flow at heater temperature rise rates from 250 K/s to 19 000 K/s and subcooling level from 23 to 103 K. The effect of temperature conditions on the relative fraction of bubbles smaller than 50 μm is studied. A significant contribution of microbubbles at deep subcooling of the liquid and high rate of temperature rise of the heater surface was revealed. Keywords: nucleate boiling, microbubbles, non-steady heating.
