A model of heat transfer in gas fluidized beds

Abstract The mechanism of heat transfer at surfaces in fluidized beds is discussed and a variant of the penetration theory is developed in which the packet theory of heat transfer is modified to allow for, and describe quantitatively, property variations in the packet in the region of the surface. Property variations are described in terms of the voidage variations in the vicinity of a constraining surface which are modelled from simple geometrical considerations. The model of the heat-transfer process derived here shows good agreement with experimental data without recourse to any of the semi-empirical approximations that are features of the previous models.
