Summary

IN THE FIRST PART, A RIGOROUS NUMERICAL SOLUTION OF A THEORETICAL MODEL BASED ON LAMINAR BOUNDARY LAYER THEORY FOR POOL FILM BOILING HEAT TRANSFER FROMA HORIZONTAL CYLINDER INCLUDING THE CONTRIBUTIONS OF LIQUID SUBCOOLING AND RADIATION FROM THE CYLINDER WAS OBTAINED. THE NUMERICAL SOLUTION PREDICTED ACCURATELY THE EXPERIMENTAL RESULTS OF POOL FILM BOILING HEAT TRANSFER FROM A HORIZONTAL CYLINDER IN WATER WITH HIGH RADIATION EMISSIVITY FOR A WIDE RANGE OF LIQUID SUBCOOLING IN THE RANGE OF NON-DIMENSIONAL CLNE3 THE SECOND PART PRESENTS EXPERIMENTAL DATA ON VARIOUS LIQUIDS SUCH AS WATER, ETHANOL, ISOPROPANOL, R113, R11, LIQUID NITROGEN, AND LIQUID ARGON FOR WIDE RANGES OF SYSTEM PRESSURE, LIQUID SUBCOOLING, SURFACE SUPERHEAT AND CYLINDER DIAMETER. A NEW CORRELATION WAS DEVELOPED BY SLIGHTLY MODIFYING THE APPROXIMATE ANALYTICAL SOLUTION TO AGREE BETTER WITH THE EXPERIMENTAL DATA.
