The spray characteristics of liquid jet injected into subsonic cross-flow were investigated experimentally. Droplet sizes were measured using PDPA and Image Express. The nozzle diameter was 0.5 ㎜, and its length-to-diameter ratios (L/D) ranged from 1 to 3. Experimental results indicate that the break-up of liquid jet is distributed by many mechanism that are surface wave, shear vortex, counter rotating pair vortex etc. Spray Characteristics are symmetry according to flow direction, and SMD was increased, after some distance, it was decreased with flow direction. SMD of spray from liquid jet is increased in accordance to liquid jet direction.
