Type of article: Article

Summary

THE VAPOUR BUBBLE GROWTH AND BREAK OFF, AND TEMPERATURE DISTRIBUTION IN THE OVERHEATED LAYER DURING NUCLEATE BOILING OF LIQUIDS ARE SIMULATED NUMERICALLY. A NEW MECHANISM OF VAPOUR BUBBLE GROWTH IS SUGGESTED. ANALYTICAL RELATIONS ARE GIVEN FOR THE HEAT TRANSFER COEFFICIENT AND THE ONSET OF A DEVELOPED BOILING OF LIQUIDS. THE CALCULATED AND MEASURED INTRINSIC AND INTEGRAL CHARACTERISTICS FOR BOILING NITROGEN, OXYGEN AND HELIUM ARE OBSERVED TO BE IN GOOD AGREEMENT.
