Exergy Efficiency of Closed and Unsteady-Flow Systems [PDF]
EntropyExergy efficiency is viewed as the degree of approaching reversible operation, with a value of 100 percent for a reversible process characterized by zero entropy generation or equivalently zero exergy destruction since Xdestroyed = T0Sgen.

Exergy Efficiency of Interplanetary Transfer Vehicles [PDF]
Systems Engineering in Context, 2019 In order to optimize systems, systems engineers require some sort of measure with which to compare vastly different system components. One such measure is system exergy, or the usable system work. Exergy balance analysis models provide a comparison of different system configurations, allowing systems engineers to compare different systems configuration
