Contactless rotational concentric microviscometer

Peter Ryser, Eric Meurville, Sigfrid Straessler, Emeric Grandjean

We investigated the feasibility of a concentric rotational microviscometer which is actuated remotely. This type of sensor might find application in vivo as a passive implant. The heart of the sensor is a cylindrical rotor, actuated from a distance of up t ...

Grid Filter Models for the Large Eddy Simulation of Fluid Flows

Marc Anthony David Habisreutinger

In fluid mechanics, turbulence can occur in very simple flow geometries, for Newtonian fluids and without the need for additional flow conditions such as temperature gradients or chemical reactions. In standard cases, intuitive assumptions on the physics o ...

The Effects of Fluid Elasticity on Grid Turbulence

Richard Vonlanthen

Experiments on grid turbulence are reported for pure water and dilute Polyox WSR 301 solutions. A novel passive grid, which consists of a square mesh grid with tethered spheres, has been developed to enhance the turbulence properties. In pure water the new ...

Gravity-driven slug motion in capillary tubes

Dani Or, Ivan Lunati

The velocity of a liquid slug falling in a capillary tube is lower than predicted for Poiseuille flow due to presence of menisci, whose shapes are determined by the complex interplay of capillary, viscous, and gravitational forces. Due to the presence of m ...

The dam-break problem for viscous fluids in the high-capillary-number limit

Christophe Ancey, Steve Cochard, Nicolas Andreini

Experiments were undertaken to investigate dam-break flows where a finite volume of highly viscous fluid (glucose with viscosity μ ≈ 350 Pa s) maintained behind a lock gate was released into a horizontal or inclined flume. The resulting sequence of flow-de ...

The dam-break problem for Herschel-Bulkley viscoplastic fluids down steep flumes

Christophe Ancey, Steve Cochard

In this paper we investigate the dam-break problem for viscoplastic (Herschel- Bulkley) fluids down a sloping flume: a fixed volume of fluid initially contained in a reservoir is released onto a slope and flows driven by gravitational forces until these fo ...

Rheophysics of highly concentrated coarse-particle suspensions in a wide-gap Couette rheometer.

Christophe Ancey, Sébastien Wiederseiner

An optical visualization apparatus has been designed to measure the particle-velocity and solid-concentration profiles of highly concentrated coarse-particle suspensions in a wide-gap Couette rheometer. The main objective is to investigate the frictional-v ...

Scaling of capillary, gravity and viscous forces affecting flow morphology in unsaturated porous media

Dani Or

Interplay between capillary, gravity and viscous forces in unsaturated porous media gives rise to a range of complex flow phenomena affecting morphology, stability and dynamics of wetting and drainage fronts. Similar average phase contents may result in si ...

Fluid Avalanches on a Laboratory Scale.

Christophe Ancey

We will summarize theoretical approaches used to describe the motion of an avalanching mass down a steep slope. Focus is given to Newtonian and viscoplastic fluids. The governing equation can be obtained by assuming that the flow-depth to length ratio is s ...

Simulation of shear-driven flows

Roland Bouffanais

The research work reported in the present dissertation is aimed at the analysis of complex physical phenomena involving instabilities and nonlinearities occurring in fluids through state-of-the-art numerical modeling. Solutions of intricate fluid physics p ...
