Abstract

Exergetic, exergoeconomic and exergoenvironmental analyses of a high bypass turbofan engine used on commercial aircraft are performed to determine the magnitudes of the irreversibilities within a the system, exergy cost formation rates of product and waste exergy, and the environmental damage cost rate of engine emissions. According to this study, the GE90-115 turbofan engine produces 324.59 GJ/h- kinetic exergy rate while it consumes 4.104 kg/s Jet-A fuel. The energy and exergy efficiency values of the engine are estimated to be 51.00% and 48.05%. The fuel cost rate is calculated to be 9632.91 US$/h when the specific fuel exergy cost is found to be 14.24 US$/GJ. The specific product exergy cost is obtained to be 32.23 US$/GJ. Hovewer, the total environmental damage cost rate of engine emissions (UHC, CO and NOx) is accounted to be 4552.83 US$/h as long as the specific environmental damage cost is determined to be 14.02 US$/GJ. As a result, the specific exergoenvironmental cost is calculated to be 46.25 US$/GJ for Jet-A fuel.
