Summary

FUNDAMENTAL HEAT TRANSFER EXPERIMENTS WERE PERFORMED FOR FREEZING OF AN INITIALLY SUPERHEATED OR NONSUPERHEATED LIQUID IN A COOLED VERTICAL TUBE. MEASUREMENTS YIELDED INFORMATION ABOUT THE FREEZING FRONT, THE FROZEN MASS, THE VARIOUS ENERGY COMPONENTS, AND THE DECAY OF THE INITIAL LIQUID SUPERHEAT. FOUR COMPONENT ENERGIES WERE IDENTIFIED AND EVALUATED FROM THE EXPERIMENTAL DATA. INITIAL SUPERHEATING OF THE LIQUID TENDED TO MODERATELY DIMINISH THE FROZEN MASS AND LATENT ENERGY EXTRACTION AT SHORT FREEZING TIMES BUT HAD LITTLE EFFECT ON THESE QUANTITIES AT LONGER TIMES. NATURAL CONVECTION EFFECTS IN THE SUPERHEATED LIQUID WERE MODEST AND WERE CONFINED TO SHORT FREEZING TIMES.
