Modelling the Heat and Mass Transfer in Devices with Dense-Layer Dispersed Systems
Abstrak
The work is devoted to the processes of heat and mass transfer in moving and stationary dense layers of dispersed materials. One and two-component models of heat and mass transfer in a layer with internal heat sources caused by chemical and phase transformations in the presence of submerged heat exchange processes are given. A review of the literature showed that for a layer containing heat sources, not only information on these parameters is missing, but also methods for their determination. This paper describes the theoretical basis that forms the analytical dependencies of such methods. Satisfactory qualitative and quantitative agreement between experimental and calculated data indicates that the models accurately describe the main patterns of heat transfer in a blown layer with submerged heat transfer surfaces. The research results showed that when calculating temperature fields, reliable information is needed on the heat transfer coefficients of the layer and its components.
