A New Simple Method for Estimating Exergy Destruction in Heat Exchangers [PDF]
Entropy, 2013 This paper presents an abbreviated method for estimating exergy destruction in a heat exchanger, requiring only black-box data of the exchanger’s inputs and outputs, and eliminating part of the mathematical difficulties associated with the calculations.

An examination of exergy destruction in organic Rankine cycles
International Journal of Energy Research, 2008 The exergy topological method is used to present a quantitative estimation of the exergy destroyed in an organic Rankine cycle (ORC) operating on R113. A detailed roadmap of exergy flow is presented using an exergy wheel, and this visual representation clearly depicts the exergy accounting associated with each thermodynamic process.

Exergy Destruction and Entropy Generation in Desalination Systems [PDF]
Proceedings of 3rd International Electronic and Flipped Conference on Entropy and Its Applications, 2016 The impetus for new tools for a comprehensive and accurate analysis of energy utilization and industrial systems comes from the need for sustainable development that could be impeded by exhausting energy sources and deteriorating environment. Exergy evaluation provides insight to achieve highest technological efficiency at the lowest cost while meeting
