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 ... -
Application of thermodynamic laws on a military helicopter engine
(Pergamon-Elsevier Science LTD, 2017)By definition, a turboshaft engine is simply a gas turbine used to deliver shaft power such as to a helicopter rotor. This paper presents the energetic and exergetic analyses of a turboshaft engine which is used for military ... -
An assessment of cruise NOx emissions of short-haul commercial flights
(Pergamon-Elsevier Science LTD, 2017)Cruise NOx emissions of aircraft are an important input parameter for studies investigating climate change due to their ability to alter the concentrations of certain trace gases, such as ozone, methane, and hydroxyl in ... -
The effects of hydrogen fuel usage on the exergetic performance of a turbojet engine
(Pergamon-Elsevier Science LTD, 2018)In this study, the hydrogen fuel effect on the exergetic performance of a turbojet engine used in a military trainer aircraft is investigated. For the first step, the performance assessments of the exergetic performance ... -
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, ... -
Investigating actual landing and takeoff operations for time-in-mode, fuel and emissions parameters on domestic routes in Turkey
(Pergamon-Elsevier Science LTD, 2017)Operational landing and takeoff standards developed by the International Civil Aviation Organization (ICAO) in the 1970s, have been widely-used in fuel consumption and emissions models or inventory studies. However, these ... -
Modeling and validation of temperature changes in a pouch lithium-ion battery at various discharge rates
(Pergamon-Elsevier Science LTD, 2016)This paper deals with the thermal modeling of temperature rise in a pouch lithium -ion battery with LiFePO4 (also known as LFP) cathode material. The developed model represents the main thermal phenomena in the cell in ... -
Using exergy for performance evaluation of a conceptual ramjet engine burning hydrogen fuel
(Pergamon-Elsevier Science LTD, 2018)Ramjet engines are widely-used devices in the defence industry and have military applications. These engine types, preferred in many fields, are known to act according to the laws of thermodynamics. For this reason, exergy ...
