Abstract
In this article, exergetic methodology is applied for a low bypass turbofan engine at maximum power setting. The engine is a low-bypass (0.96–1) turbofan engine and its variants fitted to the 737-100/200 all comprise six low-pressure compressor (LPC) stages, seven high-pressure compressor (HPC) stages, a single HP turbine (HPT), and finally three LPT stages. At the end of the analysis, the most irreversible units in the system are found to be the combustor and the fan/LPC, with exergy loss rates of 18.7 and 2.486 MW, respectively. The exergy efficiencies of the fan/LPC, the HPC, and combustor are 0.856, 0.845, and 0.744, respectively. For the HPT and LPT, the exergy efficiencies are calculated to be 0.98 and 0.963, respectively.
