3D finite element model of semi-solid permeability in an equiaxed granular structure

A multi-domain finite element formulation has been applied to determine the semi-solid permeability of an equiaxed granular structure. The granular model was constructed from a Voronoï tessellation algorithm. The liquid-solid interface is represented impli ...

Reduced formulation of a steady fluid-structure interaction problem with parametric coupling

Gianluigi Rozza, Toni Mikael Lassila

We propose a two-fold approach to model reduction of fluid-structure interaction. The state equations for the fluid are solved with reduced basis methods. These are model reduction methods for parametric partial differential equations using well-chosen sna ...

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 ...

Persistent correlation of constrained colloidal motion

Sylvia Jeney

We have investigated the motion of a single optically trapped colloidal particle close to a limiting wall at time scales where the inertia of the surrounding fluid plays a significant role. The velocity autocorrelation function exhibits a complex interplay ...

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 ...

Unified macro-to-microscale method to predict two-phase frictional pressure drops of annular flows

John Richard Thome, Andrea Cioncolini

The study considers the prediction of pressure gradients in adiabatic gas-liquid annular two-phase flow in the macro-to-microscale range Twenty-four empirical correlations have been tested against an experimental data bank drawn together in this study cont ...

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 ...

Reduced basis method for the shape optimization of racing car components

Claudia Günther

In this work we apply reduced basis methods to parametrized airfoils configurations to study inviscid potential, thermal and viscous flows. Parametrization includes geometry, ground effect and airfoils interaction. ...
