Abstract : An experimental study of droplet-turbulence interactions under simulated fuel spray conditions has been conducted. The behavior of individual droplets transversely injected into laminar and turbulent flows has been characterized by measuring droplet position, shape and size as a function of time. From these measurements new information has been obtained on the effects of vaporization and unsteady curvilinear motion on droplet drag and lift in laminar flows. These measurements have also provided new data which characterize the effects of turbulence on droplet drag, dispersion and secondary breakup.
