XXI ICTAM, 15–21 August 2004, Warsaw, Poland INERTIAL MIGRATION OF RIGID SPHERICAL PARTICLES IN POISEUILLE FLOW

A neutrally buoyant particle in pipe flow is known to undergo a radial migration for finite Reynolds number flows. This effect was first observed by Segré and Silberberg (1962), who noted a radial equilibrium position at a radius r = 0.6R in a pipe of radius R, in conditions of finite but low Re. These results have been extended to show that the equilibrium position of the particles is moved to...

Inertial migration of spherical particles in circular Poiseuille flow at moderately high Reynolds numbers

The inertial migration of spherical particles in a circular Poiseuille flow is numerically investigated for the tube Reynolds number up to 2200. The periodic boundary condition is imposed in the streamwise direction. The equilibrium positions, the migration velocity, and the angular velocity of a single particle in a tube cell are examined at different Reynolds numbers, particle-tube size ratio...

Hydrodynamic interactions of spherical particles in Poiseuille flow between two parallel walls

We study hydrodynamic interactions of spherical particles in incident Poiseuille flow in a channel with infinite planar walls. The particles are suspended in a Newtonian fluid, and creeping-flow conditions are assumed. Numerical results, obtained using our highly accurate Cartesian-representation algorithm Physica A 356, 294 2005 are presented for a single sphere, two spheres, and arrays of man...

Lateral Migration and Rotational Motion of Elliptic Particles in Planar Poiseuille Flow

Simulations of elliptic particulate suspensions in the planar Poiseuille ow are performed by using the lattice Boltzmann equation. E ects of the multi-particle interaction on the lateral migration and rotational motion of both neutrally and non-neutrally buoyant elliptic particles are investigated. Low and intermediate total particle volume fraction fa = 13%, 25%, and 40% are considered in this...

Driven inertial waves in spherical Couette flow.

Dynamo action in the cores of planets and stars gives rise to their magnetic fields. We explore spherical Couette flows in liquid sodium as a laboratory model of the Earth’s core. Below, we image various spatiotemporal magnetic-field modes present in spherical Couette flows. Our apparatus is comprised of two independently driven rotating spheres, radii 20 and 60 cm, with sodium filling the gap ...
