Particles in Fluids

Abstract

Behavior of a single isolated particle in a fluid: (1) Settling of a single isolated particle in a continuous fluid. (2) Drag force on an isolated particle. (3) Calculation of the terminal velocity. (4) Other shapes. (5) Acceleration and nonsteady motion. (6) Curvilinear motion. (7) Assemblies of particles.

The earlier chapters in this book are mostly concerned with the properties of solid particles, but in particle-processing operations the particles are surrounded by a fluid—a gas or a liquid—or perhaps by a mixture of fluids. Much of particle technology is concerned with the interaction between particles and fluids, which ...
