What the grant funds

The Combustion and Fire Systems program is part of the Transport Phenomena cluster, which also includes 1) the Fluid Dynamics program; 2) the Particulate and Multiphase Processes program; and 3) the Thermal Transport Processes program. The goal of the Combustion and Fire Systems program is to create new knowledge to support advances in clean energy, climate change mitigation, a cleaner environment and public safety. The program endeavors to create fundamental scientific knowledge that is needed for safe, clean and useful combustion applications and for mitigating the effects of fire. The program aims to identify and understand the controlling basic principles and to use that knowledge to create predictive capabilities for designing and optimizing practical combustion devices and understanding fire. Important outcomes for this program include: broad-based tools — experimental, theoretical, and computational — that can be applied to a variety of problems in combustion technologies and fire; science and technology for clean and efficient generation of power; discoveries that enable clean environments (for example, by reduction in combustion-generated pollutants); and enhanced public safety and climate change mitigation through research on wildland and building fire growth, inhibition, and suppression. Research areas of interest for this program include: Basic combustion science: Combustion of gas, liquid, and solid fuels over a broad range of temperatures, pressures, and compositions; combustion at supercritical conditions; advanced propulsion concepts; flame synthesis of materials; integration of fuel design and combustion; control of reaction pathways; development of chemical kinetics models, analytical and numerical predictive methods, and advanced diagnostic tools. Combustion science related to clean energy: Increasing efficiency and reducing pollution; production and use of renewable and/or carbon-free fuels; biomass pyrolysis, gasification, and oxidation; technologies such as oxy-fuel combustion and chemical looping combustion for carbon capture. Fire prevention: Improved understanding of building and wildland fires to prevent their spread, inhibit their growth, and suppress them; prediction and mitigation of fires in the wildland-urban interface.
