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.
