Effects of Fuel Consumption of Commercial Turbofans on Global Warming
The main objective of this study is to parametrically investigate the fuel consumption effect of commercial turbofans on global warming. In this regard, of the important parameters, specific fuel consumption of commercial turbofans is taken into consideration. In order to minimize the effect of fuel consumption on global warming, the values of engine design parameters are optimized for maintaining minimum specific fuel consumption (SFC*, g/kN s) of high-bypass turbofan engine under different flight conditions and design criteria. The backbones of optimization approach consisted of elitism-based genetic algorithm coupled with real parametric cycle analysis of a turbofan engine. For solving optimization problem a new software program is developed in MATLAB, while objective function is determined for minimizing the specific fuel consumption by considering parameters such as the fan pressure ratio (π f ), bypass ratio (α), and the fuel heating value [h PR (kJ/kg)].
