Advanced life cycle integrated exergoeconomic analysis of building heating systems: An application and proposing new indices
(ELSEVIER SCI LTD, 2018)
Advanced exergy-based analysis and assessment tools have been considered very useful tools for detecting the interactions among components of energy-conversion systems and the real potential for improving each component ...
Exergy as a useful tool for the performance assessment of aircraft gas turbine engines: A key review
(PERGAMON-ELSEVIER SCIENCE LTD, 2016)
It is known that aircraft gas turbine engines operate according to thermodynamic principles. Exergy is considered a very useful tool for assessing machines working on the basis of thermodynamics. In the current study, ...
Investigation of environmental impact caused by aircraft engines
(INDERSCIENCE ENTERPRISES LTD, 2013)
The environmental effects of exhaust gas emissions from different types of spark ignitions (SIs) - naturally aspirated and air-cooled from piston-prop aircraft engines - at the landing and take-off (LTO) phase of flight-based ...
Investigating the Effect of Turbine Inlet Temperature on the Exergetic Improvement Potential of a Small Turbojet Engine
(IEEE, 2017)
This paper analyzes and evaluates exergetic improvement rate (IPex) of the components of a small turbojet engine with various turbine inlet temperatures. The engine consists of an inlet, starter generator, a centrifugal ...
Advanced exergy analysis of an aircraft gas turbine engine: Splitting exergy destructions into parts
(PERGAMON-ELSEVIER SCIENCE LTD, 2015)
Advanced exergy analysis of an aircraft gas turbine 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 ...
Advanced exergoenvironmental assessment of a building from the primary energy transformation to the environment
(ELSEVIER SCIENCE SA, 2015)
Buildings are of great importance in terms of consumption of energy all over the world. Building sector has a significant influence over the total natural resource consumption and is significant contributors of greenhouse ...
Investigation of environmental and exergetic performance for coal-preparation units in cement production processes
(PERGAMON-ELSEVIER SCIENCE LTD, 2012)
The main objectives of the present study are to perform energy and exergy analyses of a coal-preparation unit in a cement plant and investigate the effect of varying dead state (ambient) temperatures on exergy efficiency. ...
EXERGETIC, EXERGOECONOMIC AND SUSTAINABILITY ASSESSMENTS OF PISTON-PROP AIRCRAFT ENGINES
(TURKISH SOC THERMAL SCIENCES TECHNOLOGY, 2012)
In this study, the exergetic, exergoeconomic, and sustainability aspects of piston-prop aircraft engines are comprehensively reviewed. These analysis and assessment tools are applied to a four-cylinder, spark ignition, ...
Advanced low exergoeconomic (ALEXERGO) assessment of a building along with its heating system at various stages
(ELSEVIER SCIENCE SA, 2015)
The present study deals with evaluating the performance of a building heating system along with its main components using advanced low exergoeconomic analysis method. This method combines advanced exergoeconomic with low ...
Exergoeconomic Environmental Optimization of Piston-Prop Aircraft Engines
(TAYLOR & FRANCIS INC, 2015)
In this study, exergy, exergoeconomic, exergoenvironmental analyses, and exergoeconomic environmental optimization are applied to a four-cylinder, spark ignition, naturally aspirated and air-cooled piston-prop aircraft ...
