Conductive-convective heat transfer in disperse systems with suspended particles

A film model of heat transfer between a disperse medium and a macrosurface under conditions of an ascending gas flow is suggested. Model equation (11) for the coefficient αc-c as a function of the governing factors is obtained. It is used for generalization of experimental data in various systems: a fludized bed, a circulating fluidized bed, vertical pneumotransport — described by formulas (12), (13), (15), and (16).
