Abstract
A series of microgravity experiments were performed in order to investigate flame propagation process of a n-Decane linear droplet array. In the experiments, direct images of the flame and hydroxyl [OH] radical self-emission intensity distributions on projection plane were observed and recorded. The obtained images show detailed flame propagation along a linear droplet array and around the each droplet. Also, they describe the switching process from premixed combustion of evaporated fuel to diffusive flame style around he droplet.
