The rotation of a sedimenting spheroidal particle in a linearly stratified fluid

Published in Journal of Fluid Mechanics, 2022

This work deals with the rotation of slowly settling spheroid in a density stratified fluid. This work explained the behavior of sedimenting anisotropic particles in stratified medium observed in recent experiments
