Energetic and exergetic efficiency modeling of a cargo aircraft by a topology improving neuro-evolution algorithm
(Pergamon-Elsevier Science LTD, 2016)
An aircraft is a complex system that requires methodologies for an efficient thermodynamic design process. So, it is important to gain a deeper understanding of energy and exergy use throughout an aircraft. The aim of this ...
Designation of Environmental Impacts and Damages of Turbojet Engine: A Case Study with GE-J85
(MDPI, 2014)
Between the troposphere and stratosphere layers of the atmosphere is a critical zone for collecting emissions and negative effects on the Earth (ecological, humanity, and resources). Aircrafts are the main causes of the ...
Exergy analysis of an air-blasted combustor: an application for atmospheric test rig condition
(Inderscience Enterprises LTD, 2016)
Combustion of fuel finds its importance in heating, power production and transportation. The main objective of this study is to assess the performance of an air-blasted combustor using the exergy at different combustor ...
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 ...
