SOOT FORMATION MODELING IN NONPREMIXED ETHYLENE AND ACETYLENE FLAMES

The formation of soot is a topic of interest by the scientific community due to its environmental and economic impacts. Soot is a carbonaceous material formed via incomplete combustion of organic fuels. Mathematical modeling of soot formation is important in many aspects to understand particle dynamics and combustion modeling. In this work, we model soot formation in nonpremixed flames of acetylene and ethylene. Computational Fluid Dynamics (CFD) simulations are employed to predict temperature and soot volume fraction profiles in the flames. Soot formation modeling is done using a three-equation model, and the complete CFD model is validated against experimental data from literature, yielding accurate predictions.
