Explore the fascinating world of particle behavior in complex flows through this seminar by renowned experimental physicist Elisabeth Guazzelli. Delve into the interactions between heavy particles and vortical flow structures, examining how flow configurations can either promote particle dispersion or lead to their accumulation in specific regions. Learn about an experimental setup using electroconvection to generate controlled vortices, and compare observations with point-particle simulations. Investigate the motion of single spherical particles and particle clouds, uncovering the interplay between multibody interactions and flow structures. Gain insights into natural phenomena and industrial applications involving particle-laden flows, drawing from Guazzelli's extensive expertise in fluid mechanics and particle suspensions.
