Summary

A COMPUTER PACKAGE HAS BEEN DEVELOPED TO SOLVE HEAT TRANSFER PROBLEMS WITH PHASE CHANGE AND PREDICT THE TEMPERATURE DISTRIBUTION AND PHASE-FRONT LOCATION VARIATION WITH TIME. THE FIXED-MESH PACKAGE INCORPORATES LATENT HEAT EFFECTS USING O'NEILL'S METHOD. THE TIME-DOMAIN SOLUTION USES A CENTRAL-DIFFERENCE PROCEDURE. PUBLISHED RESULTS ON FREEZING OF SLAB-SHAPED FOODSTUFFS, SOLIDIFICATION IN AN INTERNAL CORNER, A SOLIDIFICATION OUTSIDE A 270 DEG WEDGE, AND SOLIDIFICATION OF CAST STEEL ARE USED TO DEMONSTRATE THE VALIDITY OF THE NUMERICAL TECHNIQUE. UNDERGROUND FREEZING OF PIPELINES WITH AND WITHOUT FROST SHIELDS IS STUDIED, AND THE RESULTS ARE DISCUSSED.
