At the University of Michigan’s Rapid Compression Facility (RCF), experiments will be conducted to extend the high-quality, low-uncertainty experimental database of high hydrogen content (HHC) combustion kinetic benchmarks over a range of operating conditions, including pressures (10–25 atmospheres), temperatures (700–1700K), and the effects of dilution with exhaust gases (where uncertainties in third body coefficients become particularly important). Flammability limits and flame/auto-ignition inter-actions will be determined computationally and experimentally. The RCF data will provide rigorous targets for development of accurate, well validated, detailed, and reduced chemical kinetic reaction mechanisms for HHC combustion, including nitrogen oxide (NOx) chemistry.
This project will expand the experimental database of high hydrogen content (HHC) combustion kinetic benchmarks. Improving benchmark data for HHC fuels will improve the tools available for hydrogen combustor designs that will produce fewer emissions at higher temperatures. Specifically this project will conduct Rapid Compression Facility experiments to extend the high-quality, low-uncertainty experimental database of HHC combustion kinetic benchmarks at operating conditions including high pressures, high temperatures, and the effects of dilution with exhaust gases.
