Heat exchanger networks (HENs) are widely used in industry. This paper extends the entransy theory to heat-work conversion optimization in one-stream HENs. The expression for entransy loss is set up for the open system with work output. The entransy loss, as well as entropy generation, is used...

The entransy theory has been developed for heat transfer optimization. This paper extends it to optimize thermodynamic processes. The entransy balance equation of thermodynamic processes is introduced, with which the concept of entransy loss is developed. For the Carnot cycle and the...

This paper presents the relationships for the heat transfer performance of two-stream heat exchangers (THEs) and two-stream heat exchanger networks (THENs) with the entropy generation, the entropy generation number, the revised entropy generation number, the entransy dissipation, the entransy...
