The majority of attention in the field of turbulent suspensions has been focused on spherical particles [3] and particle having high aspect-ratio as long-chain polymers or elongated fibers (e.g. [4]). However, many objects found in environmental flows, such as organisms, sediment, droplets, or aggregates of these are in between these two extremes, and have aspect ratio between 1 and 10. Herein we examine an idealized model of such particles.
In particular, in this work we focus on the effect that such particles have on the background turbulent flow.
