Particle shape consideration in numerical simulation of assemblies of irregularly shaped particles

Particuology, 2011
Abstract The mechanical behavior of granular materials depends much on the shape of the constituent particles. Therefore appropriate modeling of particle, or grain, shape is quite important. This study employed the method of direct modeling of grain shape ( Matsushima & Saomto, 2002 ), in which, the real shape of a grain is modeled by combining ...

Real-Time Shape-Based Particle Separation and Detailed in Situ Particle Shape Characterization

Analytical Chemistry, 2012
Particle shape is an important attribute in determining particle properties and behavior, but it is difficult to control and characterize. We present a new portable system that offers, for the first time, the ability to separate particles with different shapes and characterize their chemical and physical properties, including their dynamic shape ...

REVIEW OF APPLIED PARTICLE SHAPE DESCRIPTORS AND PRODUCED PARTICLE SHAPES IN GRINDING ENVIRONMENTS. PART II: THE INFLUENCE OF COMMINUTION ON THE PARTICLE SHAPE

Mineral Processing and Extractive Metallurgy Review, 2005
In this article the literature on the shape of particles produced by comminution methods and the grinding condition is reviewed and presented. Some agreement and disagreement among workers for the shapes that are produced by comminution are presented. In addition, the important factors affecting the shape of particles in different comminution methods ...

THE EFFECT OF PARTICLE SHAPE ON FLUID-PARTICLE INTERACTIONS

Particulate Science and Technology, 1989
ABSTRACT Few correlations exist to predict the drag on non-spherical particles, although drag on spheres has been well characterized. A problem in developing predictive equations is the lack of adequate shape descriptors, although sphericity is a good descriptor for smooth nonspherical particles, such as geometric objects.

INFLUENCE OF SHAPE ON PARTICLE SIZE ANALYSIS

Particulate Science and Technology, 1993
ABSTRACT The purpose of this paper is to study the influence of the shape of the particles on the response of the instruments used for their measurement. This was achieved by sizing three different particle shape materials with three different particle sizers.

Particle Shape Characterization

1997
In powder technology the size characterization problems range from determining the shape of rock fragments measuring several centimeters to the problems of characterizing the shape and structure of items such as diesel soot and industrially important pigments.

Dynamic Shape Factors for Particle Shape Characterization

Particle & Particle Systems Characterization, 1985
AbstractThe need for particle shape characterization has been internationally recognised and has resulted in a number of publications proposing a variety of methods for particle shape analysis and shape description. Though very important in chemical engineering, correlations between shape parameters and bulk properties are still rare.This paper ...

Focusing in on Particle Shape

1980
While it is recognized that naturally occurring scattering particles are not always perfect spheres, nevertheless a vast amount of theoretical calculations have been made for perfect spheres. Why is this? There are two obvious and very important justifications: (1) many of the qualitative and even quantitative characteristics of particle scattering are
