## Abstract The characterization of the flow inside a packed bed requires a full description of the pore geometrical characteristics, and of the flow phenomena at local level. A twoβdimensional (2βD) network model for describing the flow phenomena in unconsolidatedβpacked beds has been developed. T

If transient heat transfer occurs in a packed bed or a reaction is carried out on the pellets, the heterogeneity of the bed is essential because of the heat flow between pellets and gas. Global heat parameters for the packed bed, such ss d,,, and a,,,, are usually derived from homogeneous models. Th
This paper has been written to complement the paper by Cohen and Metzner (1981). These authors developed a parallel channel model of the packed column which they regarded as a porous medium divided into wall, transition and interior regions. Their model is comprehensive, but involves a substantial e
