For an electric train, exergy losses can be related to the energy flows during dynamic processes …, and exergy conversion in these processes provides a meaningful measure of the industrial (<em>i.e.</em>, transportation …

Exergy is a thermodynamic concept that has been widely promoted for assessing and improving sustainability, notably in … the characterization of resources and wastes. Despite having many notable benefits, exergy is often misused by authors who … both theoretical and empirical evidence the authors present five key limitations that must be overcome before exergy can be …

A new definition of the exergy efficiency for two types of Sorption Heat Pumps (type I or conventional heat pump and … type II or heat transformer) is presented. It is based on the concept of transiting exergy which permits the quantitative … and non ambiguous definition of the useful exergy produced in each of these systems and exergy expended to accomplish the …
