Summary

THERE EXISTS A BOILING CONDITION OF SUBCOOLED LIQUID AT WHICH MANY MICROBUBBLES ARE EMITTED FROM A HEATED SURFACE. THIS PHENOMENON < MICROBUBBLE EMISSION BOILING > OCCURS EASILY IN SYSTEMS WHERE THE SUBCOOLED LIQUID REMOVES THE BUBBLES NATURALLY, AND NOT AGAINST THEIR OWN MOTION FROM THE SURFACE SOON AFTER THEIR GENERATION. THE SUBCOOLING AND THE VELOCITY OF THE LIQUID SHOULD BE VERY IMPORTANT FACTORS. THE PURPOSE OF THE STUDY WAS TO CLARIFY THE EFFECTS OF THE DEGREE OF SUBCOOLING AND VELOCITY TO THE SURFACE AND THE INTENSITY OF MICROBUBBLE EMISSION BY MEASURING TEMPERATURE AND PRESSURE FLUCTUATIONS.
