Exergy Efficiency of Closed and Unsteady-Flow Systems [PDF]

Entropy
Exergy 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.
