In the present study, Lagrangian measurements of drop motion of a two-phase spray are analyzed to estimate the collision, fragmentation, size, and velocity field of the drops. An experimental setup is designed to record fluorescence images of drops, illuminated by a planar laser sheet. The recorded images are then processed with a commercially available Lagrangian tracking software, Track. The methodology for particle identification, tracking, and size approximation in Track in the near interface region of spray is stated. With the stated methodology, the information about size, velocity, fragmentation, collision, and change in the shape of the drops are obtained. The effectiveness of the developed methodology is tested against synthetically produced images and is then applied to a liquid/liquid jet. Similar behaviors for dispersed phase fragmentation-collision and mass fragmented along axial location normalized by breakup length of the jet are reported.
