The authors have obtained minimum conditions for the irreversibility and the contact surface of double-flow heat exchange with a prescribed total heat load with various constraints imposed on the set of permissible flow temperatures. Consideration has been given to flows with a constant heat capacity and to flows with a temperature-dependent heat capacity and, in particular, changing their phase state, that are of arbitrary high heat capacity at the boiling/condensation point. It has been shown that the obtained relations yield the existence of realizability limits of the process and relations have been derived to calculate them. For variable-heat-capacity flows, the entropy production in their mixing has been obtained. [ABSTRACT FROM AUTHOR] |
