TRANSIENT HEAT-TRANSFER IN A FIXED-BED OF SLAB-SHAPED AND SPHERICAL-PARTICLES WITH INTRAPARTICLE CONDUCTION

The mathematical equations for heat transfer between a flowing fluid a nd both slab-shaped and spherical particles with intraparticle conduct ion in a fixed bed, are numerically solved using the method of lines. The solution for spherical particles was used to confirm previous resu lts for zero and non-zero Blot numbers. Conditions are identified unde r which heat transfer to beds of slabs should not be approximated by a vailable solutions for spheres.
