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 ...

Thermal and dynamic mechanical properties of blends of bitumen with metallocene catalyzed polyolefins

John Christopher Plummer, Chiara Spadaro

A high penetration grade bitumen has been blended with up to 50 wt% of two different grades of metallocene catalyzed linear low density polyethylene (m-LLDPE) in order to investigate the potential of these and similar copolymers as a substitute for styrene ...

Fluid-Structure Interaction Problems in Hemodynamics

Paolo Crosetto

In this work we aim at the description, study and numerical investigation of the fluid-structure interaction (FSI) problem applied to hemodynamics. The FSI model considered consists of the Navier-Stokes equations on moving domains modeling blood as a visco ...

Effects of the foot evolution on the behaviour of slow-moving landslides

Alessio Ferrari, David Gonzalez

The paper presents a time-dependent 2D numerical model which has been developed with the purpose of highlighting the effects of the slope foot evolution on the behaviour of slow-moving landslides. The model allows to quantitatively analyse how foot mass va ...

Intracranial Stents Being Modeled as a Porous Medium: Flow Simulation in Stented Cerebral Aneurysms

Nikolaos Stergiopoulos, Philippe Reymond, Luca Augsburger

Intracranial aneurysms may be treated by flow diverters, alternatively to stents and coils combination. Numerical simulation allows the assessment of the complex nature of aneurismal flow. Endovascular devices present a rather dense and fine strut network, ...

Localized edge states for the transition to turbulence in shear flows

Tobias Schneider

In parallel shear flows like pipe flow or plane Couette flow, laminar and turbulent dynamics coexist. The boundary between the two types of dynamics shows up clearly in studies that monitor the life time of a perturbation, i.e. the time it takes to relamin ...

Analysis of the role of turbulence in curved open-channel flow at different water depths by means of experiments, LES and RANS

Koen Blanckaert

In order to unravel the main flow and secondary flow characteristics and the role of turbulence in a curved single-bend open-channel flow, large-eddy simulations (LES) and Reynolds-averaged numerical simulations (RANS) were carried out and compared with ex ...

Improved United-Atom Force Field for 1-Alkyl-3-methylimidazolium Chloride

Berend Smit, Ting Chen

We have developed a united atom (UA) nonpolarizable force field for 1-alkyl-3-methyl-imidazolium chloride ([Cnmim][Cl], n = 1, 2, 4, 6, 8), a potential solvent for the pretreatment of lignocellulosic biomass. The charges were assigned by fitting the electr ...

Polymer Viscoelasticity in Shear

Fabienne Meier

Polymer materials may exhibit significant viscoelastic behaviour under various type of deformations. A model that can describe various viscous behaviours in simple tension was proposed in a previous work of the laboratory of biomechanical orthopedics. This ...

Measurements of wall shear stress with the lattice Boltzmann method and staircase approximation of boundaries

Jonas Marcel Lätt

We analyze the accuracy of wall shear stress measurements in lattice Boltzmann simulations that are based on a voxel representation of the geometry and staircase approximation of boundaries. Such approximations are commonly used in the context of lattice B ...
