Exergy and cumulative exergy use analysis

, 2016
Exergy is a thermodynamic metric that represents the amount of useful energy one can obtain out of an object in a given reference environment. The exergy concept is used in several applications: from the analysis of industrial processes to economic, sustainability and ecosystem analysis.

How do exergy-based indicators respond to physical habitat changes?

Ecological Indicators
Eco-exergy and specific eco-exergy are thermodynamic indicators widely used in recent decades to monitor the ecological status of aquatic ecosystems. However, there is still a gap in the knowledge of how these indicators respond to variations in stream ...

Exergy Analysis of a Ground-Coupled Heat Pump Heating System with Different Terminals

Entropy, 2015
In order to evaluate and improve the performance of a ground-coupled heat pump (GCHP) heating system with radiant floors as terminals, an exergy analysis based on test results is performed in this study.

The Exergy of Lift, and Aircraft Exergy Flow Diagrams

Advanced Energy Systems, 2001
Abstract Aside from incidental, auxiliary loads, in level flight the principal load on the aircraft propulsion engine is the power required to provide the continuous lift. To construct an exergy flow diagram for an aircraft — for example, for the purpose of exergy costing — an expression is needed for the exergy delivered to (and by) the

Exergy Efficiency of Closed and Unsteady-Flow Systems

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.
