Correlations of exergy destruction during combustion for internal combustion engines
International Journal of Exergy, 2015The greatest destruction of exergy for internal combustion engines is a result of the combustion process. The fundamental sub–processes which contribute to the combustion irreversibility include mixing, heat transfer and chemical reactions. This work used an engine cycle simulation to provide quantitative connections between the exergy destruction, and

Unsteady exergy destruction of the neuron under dynamic stress conditions
Energy, 2013Abstract Just like all physical systems, biological systems also obey laws of thermodynamics, and as such the useful work potential of a biological system is its exergy. In some studies, exergy of living systems is considered with respect to work performance of humans in offices or buildings; however the exergy analysis of biochemical reactions in a ...

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.

Optimal control strategy for minimization of exergy destruction in boiler superheater
Energy Conversion and Management, 2013Abstract Steam temperatures in large capacity boilers of modern electric power stations are maintained closely around the design specification by spraying water in the superheater (SH) attemperator to ensure safe and efficient operation and long plant life.

Study on refrigerant circuitry of condenser coils with exergy destruction analysis
Applied Thermal Engineering, 2000Abstract A numerical model of air-cooled condenser coils is proposed to investigate the coil performance. In this model, the properties of refrigerant and air, as well as six exergy destruction components associated with different sources of irreversibility are computed locally along the coil based on numerous control volumes. The governing equations

Exergy destruction minimisation of a regenerative Brayton cycle
2018In this paper, a Brayton cycle with regenerator in which an air is preheated by the exhaust gases leaving the turbine is analysed. In the model, by utilizing the air-standard assumptions, the combustion process is replaced by a constant-pressure heat-addition process in the heat exchanger where the air is heated by the stream of constant temperature ...
