Summary

A MODEL HAS BEEN DEVELOPED WHICH ASSUMES CONDUCTION AND A NATURAL CONVECTIVE HEAT TRANSFER MECHANISM THROUGH THE LIQUID LAYER UNDER THE BUBBLE AND TRANSIENT CONDUCTION FROM THE BULK LIQUID. THE TEMPERATURE OF THE BULK LIQUID IN THE VICINITY OF THE BUBBLE IS OBTAINED BY ASSUMING A TURBULENT NATURAL CONVECTION PROCESS FROM THE HOT PLATE TO THE LIQUID BULK. THE SHAPE OF THE BUBBLE IS OBTAINED BY EQUILIBRIUM ANALYSIS. THE BUBBLE DEPARTURE CONDITION IS PREDICTED.GOOD AGREEMENT HAS BEEN FOUND BETWEEN THE BUBBLE RADII PREDICTED BY THE PRESENT THEORY AND THE ONES OBTAINED EXPERIMENTALLY.
