A review of the work conducted on particle interactions with turbulent flows provides a basis for the continued development of the diagnostics. Flow visualization techniques have provide insights to the global characteristics of the particle interaction with large scale eddies. Recent experiments conducted by a number of researchers in the field were reviewed. These data served to evaluate merits of the current theories and set a basis for future research. The development of particle size and velocity instrumentation has allowed the detailed probing of these flows and offers a potential for in-depth studies of particle interactions with the turbulent flows and the mechanisms of particle dispersion. Advances in the PDPA instrument and the data acquisition technology are described. Particle response correlations are given along with some experimental verifications using the Phase Doppler Particle Analyzer (PDPA) Examples of data obtained with the instrument are presented.
