This Project Grant award of $429,999.00 from the National Science Foundation's Engineering program (CFDA 47.041) aims to create and validate a multiscale, physics-based, data-driven model for ammonia combustion. The research will address key knowledge gaps in ammonia combustion by integrating automated theoretical calculations, targeted experimental measurements, and uncertainty-quantified modeling. This will produce the first ammonia combustion model specifically tailored for engine design applications. The resulting data, models, and multiscale data-driven approach are also expected to enable better predictive understanding of other complex reacting systems, including energetic materials/propellants, planetary atmospheres, and hypersonics. The award is being provided to The Trustees of Columbia University in the City of New York, which will execute the project from August 1, 2025 through July 31, 2028.
