AbstraGThe

Dlsperslon-Concentnc Model was found to be theoretically sound provided that large axial flmd &spers~on coeffiaents gwen by eqn ( 21) are assumed The par&le-to-flud Nusselt numbers were ConsIdered to be large on the Mod&ed D-C Model but the Nusselt numbers on Contmuous Sohd Phase Model of Llttman et al were found to decrease anomalously as Reynolds number decreases

The thermal frequency response of beds packed with glass and metallic particles has been measured in the range of Reynolds numbers from 0.05 to 330. Values of the coefficients of axial dispersion of heat, intraparticle thermal conductivity and fluid-particle heat transfer coefficients have been foun

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
