The primary objectives of this Purdue University project are to develop experimental methods, kinetic models, and numerical tools to quantify and predict the impact of exhaust gas recirculation (EGR) on NOx and CO emissions, combustion kinetics, radiation heat transfer, turbulent combustion, and combustion instabilities for HHC fuels by using laminar and turbulent flow reactors and gas turbine combustors operating at high temperatures and pressures. This project will provide detailed data for improving chemical kinetic models of EGR effects, supply insight into the effects of EGR on flame speeds and turbulent flame structure, and assess the impact of EGR on emissions in a high-pressure combustion test rig.
This project will focus on the impact of exhaust gas recycle (EGR) when used with high hydrogen content (HHC) fuels. Improving the understanding of hydrogen combustion under these conditions will aid in developing improved combustion technologies that deliver higher temperatures while keeping emissions low. Specifically, this project will develop experimental methods, kinetic models, and numerical tools to quantify and predict the impact of EGR on nitrogen oxides and carbon monoxide emissions, combustion kinetics, radiation heat transfer, turbulent combustion, and combustion instabilities for HHC fuels by using laminar and turbulent flow reactors and gas turbine combustors operating at high temperatures and pressures.
