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 ...
Investigating the exergetic and environmental effects of subcooling and superheating processes on the performance of direct expansion systems
(Springer International Publishing, 2014)
Recently, subcooling and superheating applications, which are proposed as an approach for the efficient use of energy, have positive effect on the emission next to increasing the energy efficiency. This study examines ...
Exergy analysis of a turbofan aircraft engine
(Inderscience Enterprises LTD, 2009)
An exergy analysis is reported for a General Electric turbofan engine (the CF6-80) using sea-level data. The effects on exergy efficiencies and exergy destructions are investigated of modifying the isentropic efficiencies ...
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 ...
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 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 ...
Exergetic analysis of an aircraft turbofan engine
(John Wiley & Sons LTD, 2007)
The main objective of the present study is to perform an exergy analysis of a turbofan kerosene-fired engine with afterburner (AB) at sea level and an altitude of 11000 m. The main components of this engine include a fan, ...
