Outline of Final Research Achievements

In order to realize clean combustion method utilizing high temperature and low oxygen concentration ambient condition, this study was aimed to obtain the fundamental data experimentally. The experiments were mainly conducted to measure the flame temperature and soot concentration distributions in the spray flame by using the two color method. From the experiments, it was explored that the dominant parameters determining the flame temperature are ambient O2 concentration and ambient temperature. It was also explored that the soot production region can be subdivided into the head vortex region and the following quasi-steady region. Not only the O2 concentration and ambient temperature but also the ambient density give the strong effect on the soot production of both regions.
