A proper analysis and design of the gas-particle mixing process enhances process qualities and efficiencies. In this contribution, an experimental study of the interaction of gas phase flow coherent structures with particles in a two-phase jet flow is presented. Radial profiles of particle mean velocities, particle sizes, rms velocities, turbulence intensities, and the “interparticle arrival time (IAT)” distribution have been investigated by means of phase Doppler anemometry. The experiments have been executed in a jet at different axial and radial distances from the nozzle. The variation of the initial velocity conditions, particle diameter distributions, and particle loadings yield important information about the local flow structures and their effect on the macroscopic as well as the turbulent particle transport between the jet center and the outer shear layer. The interparticle arrival time distribution proves to be an important tool to identify regions where large-scale coherent structures influence the particle distribution and tend to form particle clusters. The derived extensive experimental data set for the particle behavior in a two-phase jet may serve as a base for the detailed validation of numerical simulations of dispersed two-phase flow behavior, including strong phase interactions between gaseous and particulate phases.
