Title: Heat and mass transfer during drying in cylindrical packed beds

Abstract

In this paper, the authors present a numerical simulation of forced convection drying of granular products. The granular product is in a vertical cylinder opened at both ends and exposed to a constant wall heat flux. The authors have established a general formulation of heat and mass transfer in the medium. The solution of the equation set is carried out using a finite volume method with axisymmetrical coordinates. Here they study the time-space evolution of temperatures and water content fields, drying kinetics, and heat flux exchange with the exterior. They have also reported, in the course of this study, the effects of considering intermittent flow (the fluid is periodically blown by the bottom, then by the top of the cylinder).
