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 …

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

A detailed equation is proposed for the force exerted on a sphere that accelerates
rectilinearly in an otherwise still fluid. In addition to the buoyant force, the fluid exerts forces …

This work reports results of numerical simulations of viscous incompressible flow past a
sphere. The primary objective is to identify transitions that occur with increasing Reynolds …

Numerical simulations of flow around a rigid sphere, subjected to a sudden acceleration (or
deceleration) in relative velocity, are considered. Particular attention is paid to the interaction …

The unsteady force acting on a sphere that is held fixed in a steady uniform flow with small-
amplitude oscillations is evaluated to O (Re) for small Reynolds number Re. Good …

The steady axially symmetric incompressible flow past a sphere is investigated for Reynolds
numbers, based on the sphere diameter, in the range 0· 1 to 40. The formulation is a semi …
