Modelling heat transfer between solid particles

A population balance model is presented for describing the direct particle- to-particle heat transfer in fluid-solid processing systems. In developing the model, simple kinetic equations are assumed to describe the heat transf er process, but the particle-particle interactions are considered stochasti c. A new approach is used to develop the population balance equation. The m oment equations are derived and analysed. The time evolution of the populat ion density function, determined by numerical solution of the integro-diffe rential equation, is also presented. (C) 2000 IMACS. Published by Elsevier Science B.V.
