This $580,000 Project Grant award from the National Science Foundation's (NSF) Engineering program (CFDA 47.041) supports research at the University of Connecticut (UConn) to unravel the kinetics of soot inception in carbon-rich laminar premixed flames. The key objectives are to quantify electrically neutral and charged flame products, including small molecules, polycyclic aromatic hydrocarbons (PAHs), molecular clusters, and soot nuclei. Measurements will be performed across flames with different reactant compositions and temperatures to clarify the effect of electric charge on PAH clustering, a process that is often neglected. The research aims to improve modeling of soot formation, which is critical for designing cleaner combustion devices that can satisfy global energy and propulsion needs. The five-year project period runs from May 2025 to April 2030. No subawards are planned under this grant.
