The existing model equations governing the accelerated motion of a spherical particle are
examined and their predictions compared with the results of the numerical solution of the full …

The inclusion of the history term (often called “the Basset term”) in the equation of motion of
a sphere makes this equation non-explicit in the velocity or acceleration. For this reason, the …

In this paper, we study the effect of the Reynolds number (Re) on the dynamics and vortex
formation modes of spheres rising or falling freely through a fluid (where Re= 100–15000) …

Unsteady flow due to an oscillating sphere with a velocity U0cosωt', in which U0 and ω are
the amplitude and frequency of the oscillation and t'is time, is investigated at finite Reynolds …

A full numerical simulation based on spectral methods is used to investigate linearly
accelerating and decelerating flows past a rigid sphere. Although flow separation does not …

This study is concerned with the unsteady motion of two solid spherical particles in an
unbounded incompressible Newtonian flow. The background flow is uniform and can be …

This study focuses on the effect of spatial non-uniformity in the ambient flow on the forces
acting on a spherical particle at moderate particle Reynolds numbers. A scaling analysis is …

In this article, we investigate the motion of a solid spheroid particle in a simple shear flow.
Using a lattice Boltzmann method, we examine individual effects of fluid inertia and particle …

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 …
