Drifting snow threshold measurements near McMurdo station, Antarctica: A sensor comparison study

Katherine Colby Leonard

We present the results of an Antarctic spring field study of snow drift threshold measurements made using two custom drift sensors and a commercial parts-counting device. All three sensor types worked well at detecting drifting snow events, but the sensors ...

Deposition Processes with Hardcore Behaviour

Particles are deposited onto a surface with discrete sites. They are subject to an inhibition by which they cannot pass close by a particle already fixed on the surface. This implies that the surface builds up with vertical gaps between the particles. In t ...

Particle Manifold Method (PMM) for Multiscale Continuous-Discontinuous Analysis

Liang Sun

It is important to consider the microstructure of a material when studying the macroscopic mechanical properties. Although special equipments have been used for micromechanics study through experimental tests, it is limited by instruments and reproducibili ...

Experimental investigation of a breaking size segregation wave in a dry granular flow

Christophe Ancey, Nicolas Andreini, Gaël Epely Chauvin, Sébastien Bustamante

The objective of this paper is to provide evidence of the existence of breaking size-segregation waves in dry granular flows down inclined chutes. A flume was initially filled to a constant depth with a bimodal mixture of spherical particles that were reta ...

Phase behaviour of the symmetric binary mixture from Thermodynamic Perturbation Theory

Nicolas Dorsaz, Giuseppe Foffi

We study the phase behaviour of symmetric binary mixtures of hard core Yukawa (HCY) particles via thermodynamic perturbation theory (TPT). We show that all the topologies of phase diagram reported for the symmetric binary mixtures are correctly reproduced ...

Segregation, recirculation and deposition of coarse particles near two-dimensional avalanche fronts

Christophe Ancey

Stratification patterns are formed when a bidisperse mixture of large rough grains and smaller more mobile particles is poured between parallel plates to form a heap. At low flow rates discrete avalanches flow down the free surface and are brought to rest ...

Single-particle oxidation state and morphology of atmospheric iron aerosolsle

Satoshi Takahama

Sixty-three iron-containing particles from five field campaigns (PELTI, ACE-Asia, MILAGRO (urban location and aloft on NCAR C-130), INTEX-B) were characterized with scanning transmission X-ray microscopy and near-edge X-Ray absorption fine structure L-edge ...

Analyzing the scattering properties of coupled metallic nanoparticles

Hans Peter Herzig

We apply the boundary element method to the analysis of the plasmon response of systems that consist of coupled metallic nanoscatterers. For systems made of two or more objects, the response depends strongly on the individual particle behavior as well as o ...

Geant4—a simulation toolkit

Sebastiana Gianì

Geant4 is a toolkit for simulating the passage of particles through matter. It includes a complete range of functionality including tracking, geometry, physics models and hits. The physics processes offered cover a comprehensive range, including electromag ...

Inverse grading in granular flow

The current work concerns with the parametrical dependencies of inverse grading in granular flows from material properties of individual particles involved in the flow. The investigations were initiated and motivated by the search for an explanation of the ...
