Summary

IN THE PAPER THE USE OF THE BOUNDARY INTEGRAL EQUATION METHOD (BIEM) FOR MULTIDIMENSIONAL PROBLEMS WITH A MOVING PHASE-CHANGE INTERFACE IS EXPLORED. THE METHOD IS SHOWN TO BE SUITED TO HEAT TRANSFER PROBLEMS WHERE THE FIELD EQUATIONS ARE LINEAR IN EACH REGION AND THE BOUNDARY OR INTERFACE MATCHING CONDITIONS ARE BOTH HIGHLY IRREGULAR AND NON-LINEAR. TO ILLUSTRATE THE VERSATILITY OF THIS TECHNIQUE THE BIEM IS APPLIED TO A PREVIOUSLY UNSOLVED PROBLEM: THE MELTING/FREEZING AROUND A PIPE BURIED IN A SEMI-INFINITE DOMAIN WHERE THE MELTING/FREEZING IS INITIATED AT THE FREE SURFACE AND THE MEDIUM IS INITIALLY NOT AT THE PHASE-CHANGE TEMPERATURE.
