Bedload transport in rivers, size matters but so does shape

open access: yesScientific Reports, 2021
Bedload transport modelling in rivers takes into account the size and density of pebbles to estimate particle mobility, but does not formally consider particle shape.

Shape-dependence of particle rotation in isotropic turbulence

open access: yes, 2014
We consider the rotation of neutrally buoyant axisymmetric particles suspended in isotropic turbulence. Using laboratory experiments as well as numerical and analytical calculations, we explore how particle rotation depends upon particle shape.

A Study on Shape-Dependent Settling of Single Particles with Equal Volume Using Surface Resolved Simulations

open access: yesComputation, 2021
A detailed knowledge of the influence of a particle’s shape on its settling behavior is useful for the prediction and design of separation processes. Models in the available literature usually fit a given function to experimental data.

Shaping Particles for Ultramicrotomy [PDF]

open access: yesMRS Proceedings, 1991
AbstractA technique for preshaping large particles of reacted glass for ultramicrotomy is described. This technique preserves delicate surface layers and results in more sections per block extending deeper into the sample than other techniques.

Phase Separation and Self-Assembly in a Fluid of Mickey Mouse Particles

open access: yes, 2015
Recent developments in the synthesis of colloidal particles allow for control over shape and inter-particle interaction. One example, among others, is the so-called "Mickey Mouse" (MM) particle for which the self-assembly properties have been previously ...

Effect of Particle Size and Constraint Conditions on Single Particle Strength of Carbonate Sand

open access: yesSensors, 2022
Carbonate sand is often encountered and utilized as construction material in offshore engineering projects. Carbonate sand particles, which are porous and angular, are found to be highly crushable under high stress conditions, whereas the mechanisms and ...

Transforming mesoscale granular plasticity through particle shape

open access: yes, 2018
When an amorphous material is strained beyond the point of yielding it enters a state of continual reconfiguration via dissipative, avalanche-like slip events that relieve built-up local stress.

Single particle crushing tests of coarse grained soil considering size and shape effects

open access: yesYantu gongcheng xuebao
Particle size and shape significantly influence the crushing behaviors of coarse grained soil. In this study, the particle scanning, particle shape analysis, and single particle compression tests on the gravel soils of high filling project of Baihetan ...

Particle Discharge Characteristics from the Nozzle of a Thin Tube Immersed in Liquid Subjected to Ultrasonic Wave Force [Translated]†

open access: yesKONA Powder and Particle Journal, 2014
A wet micro-feeder that utilizes ultrasonic wave force was designed and constructed to feed small particles into a container of wet particulate materials. The particle discharge characteristics from a nozzle with the

High Fluid Velocity and Narrow Channels Enhance the Influences of Particle Shape on Colloid Retention in Saturated Groundwater Systems Under Favorable Deposition Conditions

open access: yesFrontiers in Water, 2021
Many particulate pollutants in the environment exist in non-spherical shape, but the influences of particle shape on pollutant migration and removal in groundwater systems are not well-understood.
