both first and second law of thermodynamics. Exergy analyses were performed in order to calculate the total exergy … the second law efficiency whereas, the coefficient of performance (COP) of the cycles are comparatively less affected by … this temperature. An increase of about 75% in the second law efficiency of the GAX cycle was found as the generator …

Exergy or the available energy is based on the second law of thermodynamics and goes back to Maxwell and Gibbs. It is … the exergy content and not the energy content, that truly represents the potential of the substance to cause change …. Exergy is the only rational basis for evaluating the system performance. The aim of this project is to study in detail the …

radiation, the energy absorption efficiency has a maximum at optimal incident energy flux. As the pipe radius decreases or flow … velocity rises, the wall temperature drops for higher heat transfer coefficient, while the heat absorption efficiency increases …. Along the flow direction, the heat absorption efficiency almost linearly decreases, while the exergetic efficiency will …

second-law efficiency of 28% was found. In the integrated process, with biogas as an additional product, a higher performance …

combining the pinch technology and exergy analysis. When the heat pocket is big, hot streams in the pocket can be used to … generate a higher level utility, and the cold streams in the pocket can be heated by a lower level utility. In this way, exergy … loss can be reduced, and the process's efficiency can be improved. The heat exchange network of a hydrogen production …

In this paper, the exergy analysis of a conventional gas turbine and a gas turbine with air bottoming cycle (ABC) is … the Second Law of thermodynamics. In this study, work output, specific fuel consumption (SFC) and the exergy destruction … of the components are investigated using a computer model. The variations of the ABC cycle exergy parameters are …

is increased at higher loads and thus, the exergy efficiency is increased. … availabilities are reflected in an increase in second law efficiency with increasing load. The dual fuel cumulative work availability …

In this study, the energy and exergy efficiency results of the Wind Turbine Power Plants (WTPPs) are presented. Exergy … Turkey’s first installed (1998) wind plant (1.50MW) located in Izmir. Exergy efficiency of the power plant found to be … system in Cesme, Izmir WTPP. General energy, exergy and other performance parameters are also presented. Investigated WTPP is …

-generation technologies is developed and exemplified in this paper. The model applies a dynamic exergy analysis based on the cumulative exergy …, with a cost in primary resources that can be minimized through a proper allowance for exergy reinvestment. …

The depletion of non-renewable natural exergy resources (the thermo-ecological cost) has been accepted as the objective …
