Turbulent Flows Structures Crossing Conical Diffusers: Angle Effect Analysis using PIV Technique and POD for Post-Processing

Emna Berrich, Fethi Aloui, D Pierrat, L Gros, Anthony Couzinet, Jack Legrand

In this work, we investigated experimentally the hydrodynamics of flows crossing conical diffusers. On our previous work (Aloui et al., 2011), CFD turbulent models were validated for flows crossing the critical angle (2α=16°). Indeed, the PIV data base constructed was exploited to validate a...

HCI Engineering Integrated with Capability Maturity Models

Taisa Guidini Gonçalves, Káthia Marçal de Oliveira, Christophe Kolski

Even though coming from different communities, Software Engineering (SE) and Human-Computer Interaction (HCI) engineering have similar goals: the definition of methods, techniques and standards to support the development of software systems, and, in particular for HCI, of interactive systems....

Ergonomics of load transport in the seed harvesting ant Messor barbarus Linnæus, 1767: morphology influences transportation method and efficiency

Abel Bernadou, Antoine Felden, Mathieu Moreau, Pierre Moretto, Vincent Fourcassié

We studied in the field the load transport behaviour of workers of the polymorphic Mediterranean seed harvester ant Messor barbarus. Individual ants used two different methods to transport food items: carrying or dragging. The probability of dragging instead of carrying varied significantly with...

Scavenging Process Analysis in a 2-Stroke Engine by CFD Approach for a Parametric 0D Model Development

Stéphanie Cagin, Nachida Bourabaa, Eric Delacourt, Céline Morin, Xavier Fischer, Daniel Coutellier, Bertrand Carre, Sylvain Loumé

This paper presents a method to improve cylinder design of 2-stroke auto-ignition engine based on a CFD (Computational Fluid Dynamics) study of internal flows in the chamber and an unsteady global 0D parametric approach. In 2-stroke engine, scavenging process plays an important role regarding...

A new reduced model of scavenging to optimize cylinder design

Stéphanie Cagin, Xavier Fischer, Eric Delacourt, Nachida Bourabaa, Céline Morin, Daniel Coutellier, Bertrand Carre, Sylvain Loumé

This paper presents the development of a new scavenging model to optimize cylinder design. The developed model explicitly integrates some of the cylinder’s design and environmental variables to describe flows during the scavenging process. Then, based on the reduced model, an optimization phase was...

Relationship between brightness and roughness of polypropylene abraded surfaces

Adrien van Gorp, Maxence Bigerelle, Denis Najjar

This article proposes to analyze the relation between gloss and roughness of surfaces of polypropylene samples abraded at different magnitudes. Experiments consist of mechanical polishing at different grades, roughness profiles measurement, and specular light reflectometry with three incidence...

Using Discrete Event Simulation to evaluate Operating Theater Layout

Abdelahad Chraibi, Abdessamad Ait El Cadi, Said Kharraja, Abdelhakim Artiba

The layout planning of an organization is known to have a great impact on its quality and performance during daily operations. The Operating Theater (OT) is an organization characterized by a fluctuating production and unpredictability of care demand. This unpredictability of populations’ needs has...

A general variable neighbourhood search for the multi-product inventory routing problem

Anis Mjirda, Bassem Jarboui, Jelena Mladenović, Christophe Wilbaut, Said Hanafi

The inventory routing problem (IRP) deals with the study of the inter-relationship between two important activities in the supply chain: transportation of commodities and inventory management. In this paper, we study a variant of the multi-product IRP and we propose a general variable neighbourhood...

A quasi-static 3D model of wheelchair propulsion

Isam Hilal, Philippe Pudlo

The use of theoretical models is an alternative for studying the configuration of manual wheelchairs. Richter and Morrow proposed one of the theoretical models used to study propulsion in manual wheelchairs. However this analytical model is limited to use in the sagittal plane. This article...
