On the exergy balance equation and the exergy destruction

Energy, 2016
Abstract The exergy balance equation can be written expressing the useful work for a general process as depending on the useful work for the corresponding reversible process and the exergy destruction term. However, this can be made only if the terms (other than the exergy destruction term) on the exergy balance equation for the general process lead ...

A modified exergy analysis method for vapor compression systems: Splitting refrigerant exergy destruction

Applied Thermal Engineering, 2022
Abstract To locate the major imperfections and determine the optimization directions for developing high-efficiency vapor compression systems, a modified exergy analysis method is proposed in this study. In contrast to previous exergy analysis methods, the proposed method can split the exergy destruction of the refrigerant and simultaneously exhibit ...

First and second level of exergy destruction splitting in advanced exergy analysis for an existing boiler

Energy Conversion and Management, 2015
Abstract When complex energy systems are analyzed and when a large number of their components is observed, the destruction of exergy related to a single component is dependent on its own properties, but also on the characteristics of other components.

Sensitivity analysis of exergy destruction in a real combined cycle power plant based on advanced exergy method

Energy Conversion and Management, 2015
Abstract The advanced exergy analysis extends engineering knowledge beyond the respective conventional methods by improving the design and operation of energy conversion systems. In advanced exergy analysis, the exergy destruction is splitting into endogenous/exogenous and avoidable/unavoidable parts.

The application of exergy destruction minimization in convective heat transfer optimization

Applied Thermal Engineering, 2015
Abstract An approach of heat transfer enhancement by reducing the irreversibility of process is discussed theoretically. The irreversibility of heat transfer process has been analysed with exergy. The irreversibility of heat transfer process can be expressed with exergy destruction.

The Destruction of Exergy During the Combustion Process for a Spark-Ignition Engine

open access: yesASME 2010 Internal Combustion Engine Division Fall Technical Conference, 2010
The second law of thermodynamics provides the mechanism for assessing the quality of energy. The non-conserved property used for this assessment is called exergy, availability or available energy. For the internal combustion engine, the exergy of the fuel is distributed among work, heat transfer, exhaust, and is destroyed by several processes.

Exergy efficiency of a solar photovoltaic array based on exergy destructions

Proceedings of the Institution of Mechanical Engineers, Part A: Journal of Power and Energy, 2010
In this article, an attempt has been made to investigate the exergetic performance of a solar photovoltaic (PV) array. A detailed energy and exergy analysis has been carried out to calculate the operating and electrical parameters, exergy destruction components, and exergy efficiency of a typical PV array.

Analysis of exergy destruction in data centres

13th InterSociety Conference on Thermal and Thermomechanical Phenomena in Electronic Systems, 2012
IT equipment and systems, housed in data centres, consume a considerable amount of electricity. Most of the electrical energy consumed by the data centre IT equipment is released in the form of heat. From a second law of thermodynamics analysis point of view, the mixing of hot and cold air streams in the room caused by hot air recirculation is an ...
