Abstract

Globally, aviation produced 2.4 percent of total emissions,according to the International Council on Clean Transportation ICCT, global from commercial aviation was 707 million tons in 2013. In 2019 that value reached 920 million tons, having increased approximately 30 percent in 6 years. The purpose of this research is to investigate the emissions of three cases involving jet propellant 8 JP-8 when mixed with greenhouse gases and at equivalent ratio variations ranging from 0.5 to 2.0 and percentage variations from 50%/50% to 90%/10%. The research method utilized simulation for the combustion of jet fuel and greenhouse gases. The mixing of jet fuel and greenhouse gases includes Case 1 with 100% pure dodecane, Case 2 with a mixture of and methane, and Case 3 with a combination of and carbon dioxide. The combustion process resulted in mass fraction, flame speed, temperature, and net reaction values. The mass fraction produced 5 products: CO, O and O2. Among these, had the lowest emission values across the three cases. In Case 1, the product had the lowest value of 547715.1 at an equivalent ratio of 2.0. In Case 2, the product at an equivalent ratio of 1.5 had the lowest value of 91647.82 with a percentage of 70% /30%. In Case 3, the N2 product at an equivalent ratio of 1.5 had the lowest value of 91647.82 with a percentage of 70% /30%.
