TRANSPORT PHENOMENA IN MULTI-PARTICLE SYSTEMS .2. PARTICLE-FLUID HEAT AND MASS-TRANSFER

Particle-fluid heat/mass transfer in multi-particle systems is considered. The approach developed extends the model for momentum transfer reported in an earlier paper. Based on a boundary layer formulation for individual particles in the sphere assemblage, the model enables a unified, consideration of fixed, distended, fluidized beds as well as isolated spheres. A simple relationship between the heat/mass transfer characteristics and the hydrodynamics of multi-particle systems is obtained. The predictions of the model are compared with reported experimental data.
