Summary

THE PROBLEM IS CHARACTERISED BY THE PRESENCE OF A MOVING PHASE-CHANGE BOUNDARY. PREVIOUS SOLUTIONS HAVE ASSUMED AN INITIAL TEMPERATURE IN THE LIQUID EQUAL TO THE PHASE-CHANGE TEMPERATURE. THE SOLUTION PROPOSED ALLOWS FOR A HIGHER INITIAL TEMPERATURE WHICH MORE CLOSELY RELATES TO GENERAL PRACTICE. THE METHOD SHOWN IS FOR LAKE-ICE FREEZING AND USES A CONVECTIVE BOUNDARY APPLIED TO THE AIR-ICE INTERFACE. THE MAIN APPROXIMATION INVOLVES A TEMPERATURE PROFILE FOR THE LIQUID TEMPERATURE DISTRIBUTION AS BEING THE SAME AS THAT FOR AN ISOTHERMAL BOUNDARY. THE ERROR IS EXPECTED TO BE SMALL.
