INVESTIGATION OF THERMODYNAMIC PERFORMANCE OF TURBOFAN ENGINE AT DIFFERENT FAN PRESSURE AND BYPASS RATIOS PART B: EXERGY ANALYSIS

In this study, exergy and exergy sustainability analysis of a turbofan engine were performed by gradually changing the bypass ratio (BPR) (4.4-11.6) and fan pressure ratio (FBR) (1.26-1.98). The analysis was performed using the EES (engineering equation solver) program. As a result of the study, the combustion chamber (CC) component was determined as the least efficient component. It was determined that as the fan pressure ratio increased, the exergy efficiency, exergy destruction ratio, exergy sustainability index, and sustainable efficiency factor of the engine increased, while the environmental impact factor and ecological impact factor decreased. It was observed that as the bypass ratio increased, the improvement potential and waste ratio decreased.
