Abstract
•Fully-resolved simulations of an ellipsoidal particle settling in Bingham fluid.•Critical yield number calculated for spheroids of many aspect ratios.•For inertial Bingham flow, the ellipsoid rotates and reaches a stable orientation.•A plastic belt surrounds the particle and constrains its rotation.•Terminal Reynolds number and drift angle tabulated for many aspect ratios.
