Summary

CLOSE-CONTACT MELTING CHARACTERISTICS OF PHASE CHANGE MATERIALS INSIDE HORIZONTAL RECTANGULAR CAPSULES ARE EXAMINED EXPERIMENTALLY. THE CAPSULES ARE HEATED ISOTHERMALLY AND 3 KINDS OF ASPECT RATIOS ARE PROVIDED. OCTADECANE AND ICE ARE USED, RESPECTIVELY. A METHOD OF ANALYSIS APPLYING NUSSELT'S LIQUID FILM THEORY TO THE CLOSE-CONTACT MELTING HEAT TRANSFER IN THE RECTANGULAR CAPSULE IS PRESENTED. THE ANALYTICAL RESULTS SHOW GOOD AGREEMENT WITH THE EXPERIMENTAL DATA. FOR THE MELTING OF ICE, IT IS FOUND THAT THE EFFECT OF NATURAL CONVECTION RESULTING FROM DENSITY INVERSION OF WATER AT 4 DEG C BECOMES SIGNIFICANT FOR LARGE STEFAN NUMBERS.
