Advanced Exergy Analysis of GT-sCO2 Combined Cycle
Journal of Thermal Science and Engineering ApplicationsAbstract The use of the supercritical carbon dioxide Brayton cycle (SCBC) for waste heat recovery from the gas turbine cycle (GTC) can enhance system performance and reduce CO2 emissions. To analyze the possibility of component optimization and the characteristics of the exergy destruction, a model of a gas turbine-supercritical carbon ...

Advanced exergy analyses of an aircraft turboprop engine (TPE)
Energy, 2017A conventional and advanced exergy analysis of an aircraft turboprop engine is presented in this paper. In this framework, the main exergy parameters of the engine components are introduced while the exergy destruction rates within the engine components are split into endogenous/exogenous and avoidable/unavoidable parts.

Advanced exergy analysis of a combined Brayton/Brayton power cycle
Energy, 2019Abstract A combined Brayton/Brayton power cycle has been investigated using the advanced exergy analysis. The combustion chamber was shown to be the component with the largest exergy destruction. However, the analysis revealed that most of the irreversibility generation at the combustion chamber was endogenous and unavoidable.
