説明
<p>A series of microgravity experiments were performed at MGLAB drop-shaft facility in Japan, in order to investigate the flame propagation process of an n-Decane linear droplet array in stagnant atmospheric air. In the experiments, all droplets in an array were simultaneously generated on the cross-point of X-shaped two SiC fibers. One end droplet of the array was ignited by a hot wire to initiate the flame spreading along the array. Direct images of the propagating flame were recorded by normal speed (30fps) digital video camcorder and hydroxyl [OH*] radical self-emission intensity distributions on the projection plane were observed and recorded with high speed (500fps) video camera. In this paper, time-resolved flame propagating mechanisms between the neighboring droplets were discussed. The observed [OH*] radical images precisely describe the flame propagating mechanisms and the switching process from premixed combustion of evaporated fuel to diffusive combustion around the droplet.</p>
