Exact solution for the motion of a rigid particle with and symmetry settling under gravity in a viscous fluid
Piotr Zdybel, Maria L. Ekiel-Jeżewska
We provide an exact and complete solution for the dynamics of a rigid particle of uniform density with and symmetry, settling under gravity in a viscous fluid at a R…

Experimental and numerical study of the dynamics of sedimenting pairs of semi-flexible fibers close to attractive `aligned' relative configuration
Harish N. Mirajkar, Chandra Shekhar, Yevgen Melikhov +2
Dynamics of two short semi-flexible fibers settling under gravity in a viscous fluid are investigated at Reynolds numbers Re << 1. We focus on fibers initially relatively close to…

Sedimenting rigid particles of certain shapes approach a stationary orientation
Chandra Shekhar, Harish Mirajkar, Piotr Zdybel +2
This work investigates experimentally and numerically the dynamics of rigid particles settling under gravity in a highly viscous fluid. We demonstrate that certain shapes: cones, c…
