The formation and extinction processes of soot particles in an unsteady spray flame in a quiescent atmosphere were investigated using a 2-D laser sheet technique. The central cross section of a flame was illuminated twice in a short time interval by laser sheets from a double-pulsed YAG laser, and two images of scattered light from soot particles were taken by two different intensified gated cameras. The velocity vectors of soot clouds at various locations in the sooting regions were estimated using the spatial cross correlation between two images. The results of the temporal and spatial variation of velocity and scattering intensity in the evolving soot clusters made it clear that soot is mainly formed in the periphery of the flame tip where the air entrainment is less and the temperature favors soot formation.
