Type of article: Article

Summary

AN ANALYTICAL MODEL OF TRANSIENT, SIMULTANEOUS HEAT, WATER, AND AIR TRANSFER IS DEVELOPED IN THE PAPER. THE RESULTING GOVERNING DIFFERENTIAL CONSERVATION EQUATIONS ARE SIMPLIFIED AND APPLIEDTO A SEMI-INFINITE MOIST SOIL WITH AN IMPERMEABLE HEAT SOURCE AT THE BOUNDARY. SOLUTIONS FOR MOISTURE AND TEMPERATURE DISTRIBUTIONS ARE GENERATED NUMERICALLY. DIFFICULTIES IN USING A MOVING BOUNDARY APPROACH ARE DIS THE SOLUTIONS PREDICT, WITHOUT USING A MOVING BOUNDARY ANALYSIS, THAT A NARROW ZONE WITH A STEEP MOISTURE GRADIENT MOVES THROUGH THE SOIL AT A RATE SUCH THAT THE VOLUME OF SOIL DRIED PER UNIT SURFACE HEAT INPUT IS CONSTANT FOR A GIVEN INITIAL MOISTURE CONTENT.
