The present work reports the measurement of planar droplet velocity field of a plain liquid jet injected into a high-speed crossflowing airstream. PIV was employed to measure the instantaneous and average droplet velocity field in the far-field region of the spray. Water was injected from a 1-mm orifice and crossflow air velocities up to 110 m/s were investigated. The approach using PIV was validated using experimental PDPA data reported in literature. The increase of droplet velocity with axial distance was clearly observed. In the region considered for analysis, the droplet velocity showed a peak in the central region suggesting contributions primarily from surface breakup.
