Heat and mass transfer in packed beds. The calculation of heat transfer in packed beds and between packed beds and the surrounding walls requires knowledge of numerous different parameters, since heat is transferred by conduction as well as by radiation and convection. If it is necessary to distinguish between particle- and fluid-temperature the heat transfer is described by a system of coupled differential equations. The differential equations are based on a heterogeneous model. The currently accepted transport coefficients needed to solve the differential equations are reviewed. The simpler case in which distinction between fluid and particle temperature is unnecessary is described by the homogeneous model. Only two transport coefficients are needed here for the calculation of the temperatures and the transferred heat, namely the effective conductivity of a packed bed and the wall heat transfer coefficients. Literature references to these coefficients are reported.
