Abstract
This work studies experimentally the angular and translational dynamics of elongated cylindrical particles settling in a quiescent fluid at low Reynolds numbers. The measured force and torque are compared with expressions accounting for the effect of fluid inertia, obtained either in the slender-rod limit or in the case of spheroids.
