Advanced exergy analysis on varying climate conditions for a 3 MW S-CO2 Brayton cycle system
Case Studies in Thermal EngineeringAiming at the problem that conventional exergy analysis cannot provide comprehensive insights into exergy destruction, advanced exergy analysis was conducted on the supercritical CO2 cycle. A more detailed breakdown of exergy destruction was revealed. In

مجلة أكاديمية الجبل للعلوم الأساسية والتطبيقية, 2022 In this study, an energy and exergy analysis of the Derna steam power plant in Libya is presented. This study aims to identify the components with high energy and exergy losses which are leading to a decrease in the performance of the power plant. The largest place losses can be figured out hence to subsequently ensure where the greatest margin for ...

Exergy destruction calculation and analysis for a Coal drying system
IOP Conference Series: Earth and Environmental Science, 2020 Abstract A coal drying system was modelled and the calculation methodology was developed to calculate the system. Then the system performance was obtained and the exergy destruction and loss in the system is 70.5 kW. The reasons of exergy destruction were tried to be explained from the perspective of energy grade.

Exergy Analysis of Fluidized Desiccant Cooling System
Entropy, 2019 One of the main challenges in the design and implementation of fluidized desiccant cooling (FDC) systems is increasing their low COP (coefficient of performance). Exergy analysis is one of the tools especially suitable for improvement and optimization of

Sustainable Development, EarlyView.ABSTRACT Sustainability represents a complex issue in which scientific knowledge inevitably coexists with the subjective perception of humans in its turn influenced by civilization, cultural but also unconscious aspects. These results emerge with evidence from a critical analysis of the main definitions of sustainability delivered by credited entities (
