A model for entrainment in avalanches and debris flows based on PIV measurements of viscous gravity currents.

Christophe Ancey, Belinda Margaret Bates

A simple experiment, designed to investigate entrainment in geophysical free-surface flows such as avalanches and debris flows, was performed using a dam break of viscous fluid which travels over a rigid bed until meeting a shallow layer of the same fluid ...

Flow field UVP measurements of a Y-shape outlet structure

Giovanni De Cesare, Alexandre Jean Pachoud

Y-shape outlet structures are used to release the turbine water into a reservoir. Classical design oftenuses a Y-shape over a certain length and with a specific opening angle. Depending on the geometry,especially in turbine mode, significant undesired flow ...

A flow sensing model for mesenchymal stromal cells using morphogen dynamics

Dominique Pioletti, Alexandre Terrier, Miguel Gortchacow

The differentiation of mesenchymal stromal cells has been shown to be af- fected by many parameters such as morphogens, flow rate, medium viscosity, and shear stress when exposed to fluid flow. The mechanism by which these cells sense their environment is ...

Incremental Model Identification of Fluid-Fluid Reaction Systems – Dynamic Accumulation and Reactions in the Diffusion Layer

Dominique Bonvin, Julien Léo Billeter, Sriniketh Srinivasan

The identification of kinetic models is an important step for the monitoring, control and optimization of industrial processes. This is particularly the case for highly competitive business sectors such as chemical and pharmaceutical industries, where the ...

Propagation of surge waves in channels with large-scale bank roughness

Anton Schleiss, Tobias Meile

elements. In addition to a prismatic reference channel, 41 different configurations of rectangular bank cavities have been investigated. The purpose was to study the effect of large-scale bank roughness on steady and unsteady flows. The macro-roughness of ...

Hydrodynamic and subdiffusive motion of tracers in a viscoelastic medium

László Forró, Sylvia Jeney, Elena Bertseva

We investigate the diffusive motion of micron-sized spherical tracers in a viscoelastic actin filament network over the time span of 8 orders of magnitude using optical-tweezers single-particle tracking. The hydrodynamic interactions of a tracer with the s ...

Experimental investigation into segregating granular flows down chutes

Christophe Ancey, Nicolas Andreini, Gaël Epely Chauvin, Sébastien Wiederseiner, Gaudenz Moser

We experimentally investigated how a binary granular mixture made up of spherical glass beads size ratio of 2 behaved when flowing down a chute. Initially, the mixture was normally graded, with all the small particles on top of the coarse grains. Segregati ...

Crowding, Intermolecular Interactions, and Shear Flow Effects in the Diffusion Model of Chemical Reactions

Nicolas Dorsaz, Giuseppe Foffi, Francesco Piazza

In the diffusion model of chemical reactions, the encounter (reaction) rate between reactant particles is governed by the Smoluchowski equation, which is a diffusion equation in a field of forces. We consider crowded environments where the particles diffus ...
