TLDR
In this paper, the authors used a Markov process to describe the movement of spheres in an inclinable pipe and showed that the radial dispersion is a function of the relative dimension of particles with respect to the macroscale of the turbulence.About:

Generation of Explosible Dust Clouds by Reentrainment and Redispersion of Deposited Dust in Air
TL;DR: In this paper, the authors discuss the generation of exposable dust cloud by reentrainment and redispersion of deposited dust in air, and three dust dispersion systems are described in the chapter: transient cloud system, open-circuit system, and closed circuit system.

Trajectories of charged particles in electrostatic powder coating systems
TL;DR: In this paper, a computer program was developed to predict the particle trajectories and particle velocities and demonstrate the effects of the various parameters at every stage of the particle flight.

Behaviour of macroscopic rigid spheres in Poiseuille flow Part 2. Experimental results and interpretation
G. Segré,A. Silberberg +1 more
TL;DR: In this paper, Segre and Silberberg showed that a rigid sphere transported along in Poiseuille flow through a tube is subject to radial forces which tend to carry it to a certain equilibrium position at about 0.6 tube radii from the axis, irrespective of the radial position at which the sphere first entered the tube.

Some measurements of particle velocity autocorrelation functions in a turbulent flow
W. H. Snyder,John L. Lumley +1 more
TL;DR: In this article, particle velocity correlations and the Eulerian spatial correlation were coincident within experimental error when the separation was non-dimensionalized by the respective integral scale, where L is the Lagrangian time integral scale and u is the turbulence intensity.

Particle motion in laminar vertical tube flow
R. C. Jeffrey,J. R. A. Pearson +1 more
TL;DR: In this article, the motion of small rigid spherical particles suspended in a Newtonian viscous liquid flowing under steady laminar conditions in a vertical tube of circular cross-section was studied.

Fluid and particle motion in turbulent dispersion—II
TL;DR: In this paper, the relative motion of particles to fluid in a turbulent dispersion is studied and an equation is derived to describe the motion of the particles to the fluid in the dispersion.

Fluid and particle motion in turbulent dispersion--1. measurement of turbulence of liquid by continual pursuit of tracer particle motion
TL;DR: In this paper, a method for measurement of turbulence quantities of fluid flow is proposed, where the motion of a swarm of small tracer particles supplied to turbulent flow is continually followed by high speed cine-photography, from which velocity correlations and energy spectra are evaluated.
