Abstract

Despite the ubiquity of turbulent flows with non-spherical particles, it has been only relatively recently that experiments have been developed to measure the motion and orientation of individual particles in a turbulent environment. Early experimental work was focused on particle motion in complex cases relevant to specific applications; Bernstein and Shapiro [1] measured the orientation of glass fibre cylindrical particles suspended in a laminar and turbulent shear flow in a water tunnel and Noel and Sassen [2] among others focused on ice crystals in clouds. Fibre-like particles have been extensively investigated during the last decades due to their direct application to several industrial sectors such as the papermaking industry, as reviewed in Voth and Soldati [3]. However, most of the research done on these flows is focused on the orientation, preferential concentration and alignment of the fibres with the turbulent flow while these are suspended and not on the turbulence effect on the particle settling rate. Also, the severe differences in the dynamics of the fibres compared with the finite-size inertial disks investigated here represents a clear differentiator between these systems.
