Predicting the Equilibrium Product Formation in Oxy-fuel Combustion of Octane (C8H18) using Numerical Modeling

Preserving the environment is a major challenge for modern society, and reducing greenhouse effect caused by combustion processes primary concern. It known that nitrogen compounds (NOx) negatively impact air quality public health. Internal engines, responsible nearly half of atmosphere's pollutants, have prompted policymakers to phase out gasoline diesel-powered vehicles in near future. Carbon capture storage technologies, including oxy-fuel combustion, are being developed address these environmental challenges. To predict exhaust pollutants such as NO CO, assuming gases resulting from fuel chemical equilibrium useful approximation. In current case study, numerical investigation on modifying oxygen content reaction mixture 21% 100% composition C8H18 air-enriched was conducted. Specifically, equilibrium-constant approach routines were tailored 10 species reported literature conditions combustion. Additionally, comprehensive analysis performed varying temperature equivalence ratio alongside level. The results emphasize intricate interplay between various factors oxy-combustion provide valuable insight into product formation Notably, non-uniform reduction N2 function O2 highlighted, with an overall rate 0.93 observed across range percentages 99%.
