Simulation of non-spherical particles in curved microfluidic channels

The paper analyzes the migration of non-spherical particles in curved micro-channels. Inertial combined with Dean drag results a reduced set stable focusing positions specific regions cross section channel. These are studied using fully resolved transient simulations particulate flows rectangular ducts oblate and prolate at bulk Reynolds number 100 dilute particle concentrations. were conducted four periodic domain, instead only one, as common practice, to investigate interaction. It is observed that different for compared those obtained spherical ones. Not focus closer upper lower walls, but also their position half width Furthermore, velocity along between shapes. Results show all shapes lead significant change outer inner halves This effect substantially more pronounced first time here. offers an independent possibility separation according shape.
