Abstract
In this paper, we 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. We 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 we study the time-space evolution of temperatures and water content fields, drying kinetics, and heat flux exchange with the exterior. W e 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).
