Thermoeconomic, Sustainability and Environmental Damage Cost Analysis of Air Cooled CT7-7A Turboprop Engine

Thermodynamic, thermoeconomic and environmental performance analyses of a high bypass turbofan engine used on commercial aircrafts

“…The general cost formation balance relation of the turbofan engine system can be written as following [6, 9- Relative cost difference    is described based on explanation of average cost per unit exergy of fuel and product of the system or component. The relative cost difference is predicted by [6,[9][10][25][26][27][28]:…”

“…The exergoeconomic factor is related to waste exergy (destruction and losses) and the total hourly levelized cost rate. The waste exergy cost flow   WEx C  and exergoeconomic factor    are estimated by [6,[9][10][25][26][27][28]:…”

“…In order to obtain TCI sys Z  , the hourly levelized cost methodology is selected for this study. The steps of this methodology are given as following[6,[9][10][25][26][27][28]; The present worth of the turbofan engine  …”

“…The tot sys Z  is obtained from [6, 9-10, 25-28]; To compare with the exergoeconomic performances of investigated systems, some performance metrics are developed and used. The exergoeconomic performance metrics are average cost per unit exergy of fuel   F c and product   Pr c which are explained as[6,[9][10][25][26][27][28]:Özgür BalliThermodynamic, thermoeconomic and environmental performance analyses of a high bypass turbofan engine...…”
