Particle shape effects on dynamic behaviors in a spouted bed: CFD-DEM study
, 2020The Computational Fluid Dynamics-Discrete Element method (CFD-DEM) approach for cylindroid particles was developed to study the effects of particle shape on spouting behaviors in a flat-bottomed spouted bed. The gas motion was modelled with k-e turbulent

Particle Shape Distribution and Particle Size–Shape Dispersion Diagram
Powder Metallurgy, 1991Abstract The present study offers a new concept in the characterisation of particle shape distribution. Metallic powders were used for investigating the shape and size distributions. A law expressing particle shape distribution was introduced and compared in its agreement with experimental data to a law previously presented by Tsubaki.

Whereas particle size and its importance is often stressed, the shape of particulate materials is often not considered in detail even though there is plenty of evidence that it is crucial for operations like transport, mixing, and fluidisation.

Particle Shape and Laser Diffraction: A Discussion of the Particle Shape Problem
Journal of Dispersion Science and Technology, 2005Abstract Particle size is considered as one of the most important characteristics of particulate materials. This is because every behavior of particles depends on particle size significantly—and vice versa: particle size can be determined from any kinds of physical responses depending on the size.

Role of particle shape on efficient and organ-based drug delivery
, 2020Encapsulation of drugs in nano- and microparticles has been known as a promising approach for efficient drug delivery. It has been well established that adjusting the physiochemical properties of these carriers concerning the specific condition of each ...
