Thermodynamic-Perfection Characteristics of Heat-Exchange Systems

Mathematical models of stationary heat-exchange systems, differing in the organization of the fluid dynamics of the flows in them, are presented. Expressions for the thermodynamic perfection characteristics of the heat exchange in such a system (the heat load on the system, the entropy production in it, and its heat-transfer coefficient) and relations between them, depending on the fluid dynamics of the flows in the system, their organization, and the kinetics of heat transfer in the system, have been derived. It is shown that the kinetics of heat exchange in a heat-exchange system influences only the heat transfer in it.
