Study of a Taylor-Couette-Poiseuille flow in an annular channel with a slotted rotor

Nicolas Lancial, Federico Torriano, François Beaubert, Souad Harmand, Gilles Rolland

This paper investigates a Taylor-Couette-Poiseuille flow in an annular channel of a slotted rotating inner cylinder, corresponding to a salient pole hydrogenerator. The purpose of this study is to improve the understanding of flow and thermal phenomena in electrical machines using a simplified…

Roughness characterization of the galling of metals

Cédric Hubert, Julie Marteau, Raphaël Deltombe, Y Chen, Maxence Bigerelle

Several kinds of tests exist to characterize the galling of metals, such as that specified in ASTM Standard G98. While the testing procedure is accurate and robust, the analysis of the specimenʼs surfaces (${\rm area}=1.2\;{\rm cm}$) for the determination of the critical pressure of galling remains…

New MIP model for multiprocessor scheduling problem with communication delays

Abdessamad Ait El Cadi, Rabie Ben Atitallah, Said Hanafi, Nenad Mladenovic, Abdelhakim Artiba

In this paper we consider scheduling tasks on a multiprocessor system, taking into account communication delays. We propose a new Mixed Integer Program (MIP) formulation that drastically reduces both the number of variables and the number of constraints, when compared to the best mathematical…

Time Series Modelling and Forecasting of Emergency Department Overcrowding

Farid Kadri, Fouzi Harrou, Sondès Chaabane, Christian Tahon

Efficient management of patient flow (demand) in emergency departments (EDs) has become an urgent issue for many hospital administrations. Today, more and more attention is being paid to hospital management systems to optimally manage patient flow and to improve management strategies, efficiency…

Complementary tribometers for the analysis of contact phenomena in grinding

Eduardo García, José Antonio Sánchez, Damien Méresse, Iñigo Pombo, Laurent Dubar

The characterization of friction and tribological phenomena occurring in grinding requires reliable experimental input data. Up to now, existing test benches exhibit important limitations. Steep thermal gradients and elastic deformations of both machine structure, and rubbing elements are the main…

Folk-IS: Opportunistic Data Services in Least Developed Countries

Nicolas Anciaux, Luc Bouganim, Thierry Delot, Sergio Ilarri, Leïla Kloul, Nathalie Mitton, Philippe Pucheral

According to a wide range of studies, IT should become a key facilitator in establishing primary education, reducing mortality and supporting commercial initiatives in Least Developed Countries (LDCs). The main barrier to the development of IT services in these regions is not only the lack of…

Sliding Mode Control of Biglide Planar Parallel Manipulator

Mustapha Litim, Benyamine Allouche, Abdelhafid Omari, Antoine Dequidt, Laurent Vermeiren

This work presents the control of a two-degree of freedom parallel manipulator using nonlinear sliding mode approach. The aim is to achieve a robust control for trajectory tracking. The control is based on the inverse dynamic model in the Cartesian space of the parallel manipulator. Kinematic…

Heat transfer coefficient distribution on the pole face of a hydrogenerator scale model

Federico Torriano, Nicolas Lancial, Melanie Levesque, Gilles Rolland, Claude Hudon, François Beaubert, Jean-Francois Morissette, Souad Harmand

This paper focuses on the effect of rotation on heat transfer mechanisms in rotating machines with the purpose to improve the understanding of thermal phenomena and cooling of hydrogenerators. Using a simplified scale model equipped with a heated pole, it was possible to measure the temperature…

A Methodology for a New Qualified Numerical Model of a 2-Stroke Diesel Engine Design

Stéphanie Cagin, Xavier Fischer, Nachida Bourabaa, Eric Delacourt, Céline Morin, Daniel Coutellier

This paper presents a methodology to determine and to formalize all the variables involved in a CFD model of a 2-stroke diesel engine. The formalization includes the establishing of the values domain and the research of relations between the variables. The formalization can be followed by a…
