|Title:||Exergo-economic analysis of a CFM56-7B turbofan engine||Authors:||Turan, Önder||Keywords:||CFM56-7B
|Issue Date:||2022||Publisher:||Pergamon-Elsevier Science Ltd||Abstract:||This paper deals with the exergoeconomic cost analysis of a high bypass turbofan engine and its components based on exergy analysis and selected economical parameters. CFM56-7B is selected for this analysis which powers Boeing 737 medium range transportation aircraft widely utilized all over the world. It has accumulated more than 105 million flight hours. Exergoeconomic analysis of engine is conducted in component level and can be performed by integration of exergy analysis and engine economic parameters. Thanks to exergoeconomic analysis, the system costs as well as exergy destructions costs within each engine components can be calculated. The study reveals out that maximum exergy cost of CFM56-7B occurs at HPT inlet as 5365.65 US$/h, however the lowest exergy cost rate as belongs to low pressure compressor work as 112.57 US$/h. Fuel cost is 2202 US$/h with unit exergy cost value of 10.33 US$/GJ based on selected fuel and economic parameters. Although unit exergy costs are around 18.5 US$/GJ value for LPT and HPT, it's calculated to be around 24-25 US$/GJ for HPC and LPC. It is thought that the cost results can be beneficial for airline customer as well as engine designer.||URI:||https://doi.org/10.1016/j.energy.2022.124936
