Confined flow of suspensions modelled by a frictional rheology

Brice Tanguy Alphonse Lecampion, Dmitriy Garagash

We investigate in detail the problem of confined pressure-driven laminar flow of neutrally buoyant non-Brownian suspensions using a frictional rheology based on the recent proposal of Boyer et al. (Phys. Rev. Lett., vol. 107 (18), 2011, 188301). The fricti ...

Impact properties of shear thickening fluid impregnated foams

Véronique Michaud, Mathieu Soutrenon

Concentrated colloidal suspensions of silica particles in polyethylene glycol exhibit a shear thickening behavior: above a critical shear rate in a confined environment, they show a steep increase of viscosity. This reversible transition from a low to a hi ...

Accounting for inertia effects to access the high-frequency microrheology of viscoelastic fluids

László Forró, Sylvia Jeney, Elena Bertseva, Frank Scheffold

We study the Brownian motion of microbeads immersed in water and in a viscoelastic wormlike micelles solution by optical trapping interferometry and diffusing wave spectroscopy. Through the mean-square displacement obtained from both techniques, we deduce ...

Quantitative cerebral blood flow imaging with extended-focus optical coherence microscopy

Theo Lasser, Arno Pino Bouwens, Tristan Bolmont, Daniel Pawel Szlag, Corinne Berclaz

Quantitative three-dimensional blood flow imaging is a valuable technique to investigate the physiology of the brain. Two-photon microscopy (2PM) allows quantification of the local blood flow velocity with micrometric resolution by performing repeated line ...

Role of viscoelastic rheologies on heterogeneous stress fields in dynamic rupture models (invited)

Jean-François Molinari, Mathilde Edmée Lucette Radiguet de la Bastaie, David Simon Kammer

Understanding how past ruptures will affect the propagation of the following ruptures, and how stress heterogeneities develop on faults are fundamental to a better comprehension of earthquake behavior. In that sense, numerical simulations provide a useful ...

Delayed voltammetric with respect to amperometric electrochemical detection of concentration changes in microchannels

Martinus Gijs, Raphaël Etienne Jean Trouillon

The time response of an electrode incorporated into a fluidic channel to variations in analyte concentration of the outer-sphere redox probe ferrocenemethanol was investigated both for amperometry (AMP) and cyclic voltammetry (CV). The experimental data sh ...

Creep behaviour of sandwich panels with rigid polyurethane foam core and glass-fibre reinforced polymer faces: Experimental tests and analytical modelling

Thomas Keller, Mário Alexandre De Jesus Garrido

This paper presents experimental and analytical investigations about the creep behaviour of sandwich panels comprising glass-fibre reinforced polymer faces and rigid polyurethane foam core for civil engineering applications. A full-scale sandwich panel was ...

Bingham-Papanastasiou and Approximate Parallel Models Comparison for the Design of Magneto-Rheological Valves

Yves Perriard, Yoan René Cyrille Civet, Daniel Grivon

Magneto-Rheological Fluids (MRFs) are smart materials whose physical properties can be controlled by an exciting magnetic field. MRFs are described as Bingham plastics with variable magnetic field dependent yield stress. Thanks to their particular features ...

Model Order Reduction in Fluid Dynamics: Challenges and Perspectives

Alfio Quarteroni, Gianluigi Rozza, Andrea Manzoni, Toni Mikael Lassila

This chapter reviews techniques of model reduction of fluid dynamics systems. Fluid systems are known to be difficult to reduce efficiently due to several reasons. First of all, they exhibit strong nonlinearities - which are mainly related either to nonlin ...
