Type of article: Article

Summary

THE EXISTENCE OF STATIONARY VAPOUR STEMS AT THE WALL IS ASSUMED IN THE MODEL. THE ENERGY FROM THE WALL IS CONDUCTED INTO THE LIQUID MACRO/MICRO THERMAL LAYER SURROUNDING THE STEMS AND IS UTILIZED IN EVAPORATION AT THE STATIONARY LIQUID-VAPOUR INTERFACE. THE EVAPORATION RATE IS GIVEN BY THE KINETIC THEORY. THE HEATER SURFACE AREA OVER WHICH THE VAPOUR STEMS EXIST IS TAKEN TO BE DRY. EMPLOYING EXPERIMENTALLY OBSERVEDVOID FRACTIONS, NOT ONLY THE NUCLEATE AND TRANSITION BOILING HEAT FLUXES BUT ALSO THE MAXIMUM AND MINIMUM HEAT FLUXES ARE PREDICTED FROM THE MODEL.
