| Research Abstract |
Fuel droplet clusters in which the droplets were arranged to form nearly spherical outer shape were actually produced as the three-dimensionally dispersed fuel systems, and the experiments of evaporation, autoignition and combustion, of those clusters were conducted where the clusters were quickly introduced into hot air ambience. The behaviors and the characteristic time periods of the evaporation, autoignition and combustion as well as the flame shapes were measured and examined through optical observation. We focused our attention especially on the cases for finer droplets and for polydisperse droplets, and those effects were examined. As the results, the knowledge and values concerning the scale effects were accumulated, and moreover, it was confirmed for the first time that the situations where the autoignition occurred after the part of the droplets were disappeared(evaporated) were reproduced.
