THERMODYNAMIC-PERFECTION CHARACTERISTICS OF HEAT-EXCHANGE SYSTEMS

Mathematical models of stationary heat-exchange systems, diff ering in the organization of the fl uid dynamics of the fl ows 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 coeffi cient) and relations between them, depending on the fl uid dynamics of the fl ows 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 infl uences only the heat transfer in it.
