Abstract

This study examines how the enhanced entrainment affects the ignition processes of micro pilot spray using a onedimentional model. The calculation model could quantitatively simulate the increasing tendency of the measured ignition delay. In addition, the simulation result demonstrated that OH radical decreased prior to the onset of the hot flame under injection conditions leading to long ignition delays. Examining the change in the entrainment rate into the spray showed that the decrease in OH radical was related to an increase in enhanced entrainment after the end of injection.
