Particle-fluid interactions observed through flow-visualization, particle concentration, particle-wall interactions, and Lagrangian statistics were all considered. These results were interpreted and compared to heavy-particle results where appropriate. Particle deposition was found to be well-described by the heavy-particle model of Young & Leeming and root-mean-square relative velocities were found to also agree with previous heavy-particle work. A model for the latter is suggested for heavy-particles and found to work similarly well for low-density particles. Non-tracer behavior was observed for bubbles with small Stokes numbers, a result not expected based on heavy-particle expectations. Local clustering of particles was observed in certain fluid structures which may indicate the importance of modeling particle collisions in future studies.
