Summary

TWO SIMPLE METHODS FOR PREDICTING THE FREEZING TIMES OF RECTANGULAR BRICKS, SLABS, CYLINDERS, AND SPHERES IN SITUATIONS WHERE BOUNDARY CONDITIONS CHANGE WITH TIME ARE PROPOSED. THESE METHODS ARE BASED ON NUMERICAL INTEGRATION OF A SIMPLE DIFFERENTIAL EQUATION DERIVED FROM A PREVIOUSLY PROPOSED MODIFICATION TO PLANK'S EQUATION. THE METHODS WERE TESTED AGAINST A THREE TIME-LEVEL FINITE DIFFERENCE SCHEME FOR VARYING COOLING MEDIUM TEMPERATURES AND SURFACE HEAT TRANSFER COEFFICIENTS. AGREEMENT WAS GENERALLY GOOD.
