This paper reports an experimental investigation of isolated fluid particles rising (or falling) in
a quiescent viscous liquid placed in an oscillating frame. Our goal is to carry out the first …

The present work presents an experimental study on a free-falling rigid sphere in a
quiescent incompressible newtonian fluid, placed in an oscillating frame. The goal of this …

The transient Stokes equations are solved inside and outside a slightly eccentric fluid
spheroid, which oscillates about its zero-mean position in an unbounded viscous medium …

The dynamics of light spheres rising freely under buoyancy in a large expanse of viscous
fluid at rest at infinity is investigated numerically. For this purpose, the computational …

The free fall of small spheres through vertically oscillated liquids has been studied
theoretically and experimentally for liquid accelerations up to 130g. Several modifications to …

The settling or rising velocity of a single spherical particle in a vertically oscillating fluid is
analysed in terms of the nonlinear perturbation technique. It is demonstrated that the …

A direct numerical simulation, based on spectral methods, has been used to compute the
time dependent, axisymmetric viscous flow past a rigid sphere. Both oscillatory flow about a …

Trajectories of 5 and 10 mm metallic and plastic particles in a quiescent liquid during their
sedimentation toward a plate were studied using experimental and numerical means, and …
