An axial viewing photographic technique has been developed which can study the turbulence characteristics of droplets in planes perpendicular to the direction of mean flow. The technique provides direct measurements of particle flux and provides measurements of the mean-square values of both the r- and φ-components of turbulent velocity fluctuations of the droplets. Results are given which show the influence of particle inertia on droplet turbulence for droplets injected into a fluid flowing turbulently in a pipe.
