Effect of Particle Shape on Size Segregation of Particles
Chemical Engineering Transactions, 2013 High-level control of the particle packing structure in a container requires the detailed analysis of particle size segregation during gravity filling. Here, we propose a method for analyzing quantitatively the effect of particle shape on the size segregation of particles using DEM (Distinct Element Method) simulation, which employ spherical particles ...

Shape‐Shifting Patchy Particles
Angewandte Chemie International Edition, 2017 AbstractA facile method to synthesize shape‐shifting patchy particles on the colloidal scale is described. The design is based on the solvent‐induced shifting of the patch shape between concave and convex features. The initial concave patchy particles were synthesized in a water suspension by a swelling‐induced buckling process.

Granular dampers: does particle shape matter?
New Journal of Physics, 2016 By means of particle-based numerical simulations using the discrete element method, we address the question of how the performance of granular dampers is affected by the shape of the granular particles.

Effect of particle shape and fragmentation on the response of particle dampers [PDF]
, 2013 A particle damper (PD) is a device that can attenuate mechanical vibrations thanks to the dissipative collisions between grains contained in a cavity attached to the vibrating structure.

Numerical Prediction of the Bulk Density of Granular Particles of Different Geometries
KONA Powder and Particle Journal, 2014 The Discrete Element Method (DEM) is increasingly used to simulate the motion of granular material in engineering devices. The most widely used shape to model granular particles is the sphere due to its simplicity ...

Multi-particle long-range rapidity correlations from fluctuation of the fireball longitudinal shape
, 2015 We calculate the genuine long-range multi-particle rapidity correlation functions, $C_{n}(y_1,...,y_n)$ for $n=3,4,5,6$, originating from fluctuations of the fireball longitudinal shape.

Shaping Particles for Ultramicrotomy [PDF]
MRS 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.

Combined Influence of Particle Shape and Fabric on the Shear Behaviour of Granular Materials
Advances in Materials Science and Engineering, 2022 The anisotropy feature is an important characteristic of granular materials in natural life and is caused by two facts: the anisotropy feature of particle shape, such as an elongated or flattened shape, and the anisotropy feature of the packing fabric ...
