NATURAL-CONVECTION HEAT TRANSFER FROM A VERTICAL CYLINDER IN SATURATED SAND.

Author(s) : YIN P. K., HITE G. E.

Summary

NATURAL-CONVECTION HEAT TRANSFER FROM A CYLINDER EMBEDDED VERTICALLY IN WATER-SATURATED OTTAWA SAND WAS INVESTIGATED EXPERIMENTALLY AND NUMERICALLY UNDER TEMPERATURES RELEVANT TO GROUND HEAT EXCHANGERSFOR HEAT PUMPS. THE MEASURED TEMPERATURE PROFILES WERE FOUND TO DEVIATE SIGNIFICANTLY FROM CONDUCTION-ONLY SOLUTIONS, INDICATING THE IMPORTANCE OF NATURAL CONVECTION. COMPARISONS BETWEEN MEASURED TEMPERATURES AND NUMERICAL PREDICTIONS OBTAINED USING A FINITE-DIFFERENCE SOLUTION TECHNIQUE IN FORTRAN DEVELOPED BY THE AUTHORS SHOWED GOOD AGREEMENT.
