Abstract
In this article, the CFM56 turbofan engine has been analyzed from the perspective of thermodynamics and exergy. Exergy is a key parameter in determining the components with the highest losses in the system and facilitating to minimize these losses and related costs. In addition to performance simulation, the use of exergy analysis helps to make this device more efficient in using energy resources, reducing costs and also reducing environmental pollution. In this research, the effect of compressor pressure ratio, turbine inlet gas temperature, fan pressure ratio, and fuel type on the production thrust of the system, energy efficiency and exergy of the system, the Specific fuel consumption of the system and the amount of environmental pollution are investigated with the parametric study of the system. The results show that the best production thrust of the system is 1.23 kN.s/kg in the compressor pressure ratio of 20. Also, the results show that the energy and exergy efficiency of the system will be 0.49 and 0.62, respectively. The results show that the most exergy destruction occurs in the nozzle.
