THEORETICAL STUDY OF ENHANCING HEAT TRANSFER OF GROOVE-SURFACE BOILING.

Author(s) : WANG J. X.

Summary

THE GROWTH OF A BUBBLE IN A GROOVE-SURFACE IS ANALYSED, AND THE PHYSICAL AND MATHEMATICAL MODELS OF FLOW AND HEAT TRANSFER OF LIQUID MICROFILM IN THE GROOVE WALL ARE PRESENTED. BY CONSIDERING THE UNSTEADY FLOW AND HEAT TRANSFER OF LIQUID ABOVE THE BUBBLE, EQUATIONS OF GROWTH AND HEAT TRANSFER OF A BUBBLE ARE OBTAINED. GROOVE-DIMENSIONS ARE ANALYSEDAND THE CHANGING RANGE OF GROOVE WIDTH AND DEPTH IS PRESENTED. THE BOILING HEAT TRANSFER AND GROWTH OF A BUBBLE OF R12 AND WATER HAVE BEEN CALCULATED. THE COMPARISON WITH EXPERIMENTS SHOWS THAT THE CALCULATED RESULTS COINCIDE WITH THE EXPERIMENTS.
