EXPERIMENTAL AND THEORETICAL-STUDIES OF CONVECTIVE HEAT-TRANSFER IN ACYLINDRICAL POROUS-MEDIUM

Convective heat transfer at constant heat flux through unconsolidated porous media has been studied both experimentally and theoretically. H eat transfer measurements have been performed for convective heat tran sfer over a wide range of operational parameters at constant heat flux es. In addition to heat transfer coefficients, pressure drop and tempe rature profiles both in radial and axial direction have been recorded. The equations of motion and energy which account for the non-Darcian effect are used to describe the flow and convective heat transfer thro ugh the porous medium. Mathematical models for the prediction of heat transfer coefficients and temperature profiles are presented which pre dict the experimental data with good accuracy. (C) 1998 Elsevier Scien ce Inc.
