Lateral migration of a 2D vesicle in unbounded Poiseuille flow
B. Kaoui, G. H. Ristow, I. Cantat +2
The migration of a suspended vesicle in an unbounded Poiseuille flow is investigated numerically in the low Reynolds number limit. We consider the situation without viscosity contr…
Tumbling Motion of Elliptical Particles in Viscous Two-Dimensional Flow
Gerald H. Ristow
The settling dynamics of spherical and elliptical particles in a viscous Newtonian fluid are investigated numerically using a finite difference technique. The terminal velocity for…
Axial Particle Diffusion in Rotating Cylinders
Christian M. Dury, Gerald H. Ristow
We study the interface dynamics of a binary particle mixture in a rotating cylinder numerically. By considering only the particle motion in axial direction, it is shown that the in…
Shape Dynamics of Interfacial Front in Rotating Cylinders
Gerald H. Ristow, Masami Nakagawa
The evolution of the interface propagation in a slowly rotating half-filled horizontal cylinder is studied using MRI. Initially, the cylinder contains two axially segregated bands…
Transition to Centrifugal Particle Motion in Rotating Drums
Gerald H. Ristow
The dynamics and the transition to the centrifugal regime are studied analytically and numerically for particles in rotating drum. The importance of the particle-wall friction coef…
Competition of mixing and segregation in rotating cylinders
Christian M. Dury, Gerald H. Ristow
Using discrete element methods, we study numerically the dynamics of the size segregation process of binary particle mixtures in three-dimensional rotating drums, operated in the c…
