Shear bands in dense metallic granular materials

Jean-François Molinari

In this paper, the phenomenon of strain localization, i.e., shear banding, in densely distributed metallic assemblies has been studied. A discrete element methodology for analyzing metallic granular materials has been put forward. In this numerical model, ...

Flow and turbulence in sharp open-channel bends

Koen Blanckaert

The sustainable development of rivers requires a knowledge on the three-dimensional mean flow field and the turbulence in complex morphologies. In a future, the computational capacity will be sufficient to simulate numerically the fine details of the flow. ...

Numerical simulation of free surface flows

Jacques Rappaz, Marco Picasso, Vincent Maronnier

A numerical model is presented for the simulation of complex fluid flows with free surfaces. The unknowns are the velocity and pressure fields in the liquid region, together with a function defining the volume fraction of liquid. Although the mathematical ...

Parallel computation and analysis of the flow in a static mixer

Mark Sawley

The use of a high-performance parallel computer system has been investigated to compute the incompressible flow and mixing efficiency of a static mixer. The flow computation is performed using a conventional Eulerian approach, by resolving the governing fl ...

Simulation of atmospheric flows over complex terrain for wind power potential assessment

When assessing the economic viability of a wind farm, the estimation of the on-site wind power potential is perhaps the most important step. The most common way of evaluating the wind power potential of an area of interest consists of making on-site measur ...

Analyse des erreurs dues à l'écoulement dans la mesure de débit par la méthode acoustique

The precise flow-rate measurement is a basic problem in the management and the exploitation of a hydraulic power-plant. The efficiency characterisation of an hydraulic machinery or of a water distribution net is linked to the accurate knowledge of the flow ...

Numerical simulations of mixing in an SMRX static mixer

Albert Renken, Thierry Meyer

The present work focuses on the flow characteristics and mixing induced by Sulzer SMRX static mixers. It is obsd. both exptl. and numerically that pressure drop increases linearly with velocity for this mixer type and that, as expected, this effect is ampl ...
