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 and both slab‐shaped and spherical particles with intraparticle conduction in a fixed bed, are numerically solved using the method of lines. The solution for spherical particles was used to confirm previous results for zero and non‐zero Biot numbers. Conditions are identified under which heat transfer to beds of slabs should not be approximated by available solutions for spheres.
