Time-resolved CO2 concentration and ignition delay time measurements in the combustion processes of n-butane/hydrogen mixtures

In order to research kinetics properties of hydrogen-enriched n-butane mixtures, this study measured the ignition delay time of nC4H10/H2 mixtures in shock tube tests and time-resolved CO2 concentrations during combustion process by combining laser absorption diagnostics. The experimental data were compared with numerical predictions from three kinetic mechanisms, and the modified NUIG Mech shows improved performances in predicting ignition...
