To combat the harmful effects of polycyclic aromatic hydrocarbons (PAHs) and subsequently formed soot particles on human health and the environment, many governments and institutions are introducing increasingly stringent regulations. To develop combustion control techniques that allow compliance with these regulations, it is essential to understand and to accurately model the chemical kinetics of fuel decomposition and especially PAH formation. While most of the available literature focuses mainly on the quantitative chemical kinetic modeling of simple combustion systems, a detailed understanding of the complex PAH formation and growth mechanisms and their influence on soot production continues to be one of the central challenges in combustion research. The proposed project targets the generation and testing of new chemical kinetic mechanisms for PAH formation leading to soot production within the context of Sustainable Aviation Fuels (SFAs). Methods used will be the Reaction Mechanism Generator (RMG), mainly developed at MIT, CANTERA, and an in-house FORTRAN code for reactive flows.
