Outline of Final Research Achievements

This research conducted microgravity experiments of flame spread over
droplet-cloud elements and randomly distributed droplet clouds in a wide pressure range in order to improve understanding of the flame spread and group-combustion excitation in fuel sprays under high-altitude relight condition of aero engines. The experiments elucidated the effects of droplet diameter ratio, local droplet interaction and ambient pressure. The results show that the thermal conduction from a burning droplet to the next unburned droplet plays an important role and the burning lifetime of the base droplet controls the flame-spread limit. Anomalous flame-spread behavior was observed over 1.5 MPa and near the group-combustion-excitation limit in randomly distributed droplet clouds. These phenomena should be elucidated in future researches.
