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.

Advanced exergy analysis of a carbon dioxide ammonia cascade refrigeration system
Applied Thermal Engineering, 2018Abstract In the present research study, a cascade NH3/CO2 refrigeration system is modeled and comprehensively assessed. Engineering Equation Solver (EES) as a potential tool is used for the simulation purpose. In order to validate the simulation code, the exergy destruction and COP is compared with an experimental data from the literature.

Advanced exergy analysis applied to a single-stage heat transformer
Applied Thermal Engineering, 2017Abstract This study presents an advanced exergy analysis of a single-state absorption heat transformer operating with a lithium bromide water solution. A traditional exergy analysis was also conducted to identify the components with the highest contribution to the exergy destruction, and an advanced exergy approach was developed to estimate a ...

A Comparative Exergy Analysis of Advanced Power Cycles Using Biomass Fuel
Volume 2: Coal, Biomass and Alternative Fuels; Combustion and Fuels; Oil and Gas Applications; Cycle Innovations, 1999This paper describes a design point study of different power generation systems using the gasification of sugar cane bagasse, which produces a low calorific value fuel. The biomass gasification is viewed as a process of drying the solid fuel and heating it up before the gasification reactions take place.
