Summary

LIQUID-SOLID CONTACT IN TRANSITION BOILING IS MODELLED BY INVOLVING TRANSIENT CONDUCTION, BOILING INCIPIENCE, MACROLAYER EVAPORATION AND VAPOUR FILM BOILING. THE PREDICTION OF LIQUID CONTACT DURATION AND TIME FRACTION AGREES REASONABLY WELL WITH EXPERIMENTAL DATA. THE LIQUID TURBULENCE DUE TO BUOYANCY FORCES AND BUBBLE AGITATION IS AN IMPORTANT PARAMETER FOR TRANSITION BOILING. SURFACE COATING (OXIDATION OR DEPOSITION) TENDS TO IMPROVE THE TRANSITION BOILING HEAT TRANSFER AND ELEVATE THE WALL SUPERHEATS AT BOTH THE CRITICAL HEAT FLUX AND THE MINIMUM FILM BOILING POINTS.
