Moderate or intense low oxygen dilution (MILD) combustion has been established as a regime with improved thermal efficiency and decreased pollutant emissions, including NOx soot. MILD the subject of numerous experimental studies, presents challenge for computational modeling due to strong turbulence–chemistry coupling within homogeneous reaction zone. Models flames in jet hot coflow (JHC) burner have typically had limited success using eddy dissipation concept (EDC) model, which incorporates...
The elevated temperature of hydrogen combustion increases the formation thermal NOx. Moderate or intense low oxygen dilution (MILD) is known to reduce NOx emissions and increase efficiency. Pressure often also used for increasing impact that pressure has on fluid dynamics chemical kinetics especially relevant in MILD conditions. Hydrogen jet flames issuing into a hot vitiated coflow were imaged using OH∗ chemiluminescence at different pressures (1–7 bar) levels (3–9% by vol.). Laminar flame...
A multi-scale U-Net machine learning (ML) model is developed to assess its validity as a surrogate for non-intrusive flame temperature measurement in jet-in-hot-coflow (JHC) flames. Inputs the are simultaneous hydroxyl (OH) and formaldehyde (CH2O) planar laser-induced fluorescence (PLIF) measurements, with target fields derived from Rayleigh scattering measurements. Coflow oxygen (O2) concentration, jet Reynolds number, coflow temperature, fuel inputs were considered dataset, resulting 33...
Experiments of autoignitive jet flames in a hot and vitiated coflow have previously shown various flame behaviors, spanning lifted to moderate or intense low oxygen dilution (MILD) combustion. For better understanding the behavior this configuration, regime diagrams ignition delay results are presented from well-stirred reactor calculations across wide range operating conditions for methane ethylene fuels. In conjunction with two-dimensional calculations, importance precursors penetration...
