Summary

THE PROBLEM OF SOLIDIFICATION OF AN INFINITE LIQUID SLAB BY LINEAR CONVECTION COOLING FROM THE ADJACENT AIR IS CONSIDERED. IT IS ASSUMED THAT AT THE INITIAL MOMENT THE SLAB HAS A CRITICAL TEMPERATURE AND THAT ON ONE SIDE THE AIR TEMPERATURE HAS DIURNAL FLUCTUATIONS OF RELATIVELY SMALL AMPLITUDE. THIS PERMITS CONSTRUCTION OF A SIMPLE FORMULA FOR THE TOTAL SOLIDIFICATION TIME. SOME PARTICULAR CASES OF THE PROBLEM ARE CONSIDERED ON THE ASSUMPTION THAT ONE SIDE OF THE SLAB IS INSULATED. ONE OF THESE CASES IS THE SIMPLEST STEFAN PROBLEM WHICH HAS AN EXACT SOLUTION. COMPARISON WITH THIS SOLUTION IS MADE.
