Abstract

Aircraft engines consume significant amounts of energy while energy sources depletion, climate change and greenhouse emission effects are rising problems worldwide. Exergy analysis has been a proven useful tool to examine and assess the performance of different energy systems. In this paper, several exergetic performance indicators are performed to evaluate CFM56-5B3 high bypass turbofan engine components namely the fan, low-pressure compressor (LPC), high-pressure compressor (HPC), combustion chamber (CC), high-pressure turbine (HPT), low-pressure turbine (LPT) and exhaust nozzle (EN) at take-off. The results indicate that the combustion chamber is the most irreversible component within the engine with an exergy destruction value of 15.456 MW and an exergy efficiency value of 85.29%. It also has the most exergetic improvement potential among the engine components with a value of 2.274 MW. In addition, the potential improvement rate is not significant in the exhaust nozzle as it has relatively low exergy destruction of 3.8 kW and excellent exergy efficiency of 98.71%.
