Abstract
Interactions of gas parcels with different histories of composition, temperature and reaction during the mixture formation in spray combustion may either enhance or inhibit the ignition depending on the cases. In this study, the impact of the history of low-temperature oxidation has been investigated by using zero-dimensional kinetic simulations with a multistage adiabatic mixing model developed to mimic the pilot injection and dual-fuel combustion. The results can be well interpreted in terms of the evolution of chain carrier species in the low-temperature oxidation and the occurrence of cool flames with the formation of the inhibitive intermediate such as formaldehyde.
