Fluid flow and convective heat transfer analysis on a rotor of wind turbine alternator with an impinging jet

Chadia Haidar, Rachid Boutarfa, Souad Harmand

This work presents a numerical and experimental study of convection heat transfer in the unconfined air gap of a discoidal technology rotor-stator system. In particular, the rotor is cooled here by an eccentric air jet impingement. The cavity is characterized by a dimensionless spacing G = 0.02 and…

Using fuzzy coding with qualitative data: example with subjective data in human-computer interaction

Pierre Loslever, Taisa Guidini Gonçalves, Káthia Marçal de Oliveira, Christophe Kolski

This article shows the role that fuzzy sets may play in the prospect of analysing qualitative data. To underline this role, a human-computer interaction (HCI) study is presented. The data coming from 20 experts concerns their judgment regarding 33 questions related to the use of HCI approaches in…

Variable neighbourhood search for financial derivative problem

Nareyus I Lawrance Amaldass, Cormac Lucas, Nenad Mladenovic

We propose a new matching problem for combinatorial optimization in financial markets. The problem studied here has arisen from the financial regulators that collect transaction data across regulated assets classes. Unlike previous matching problems, our focus is to identify any unhedged/unmatched…

Two-machine flow shop with synchronized periodic maintenance

Issam Krimi, Rachid Benmansour, Said Hanafi, Nizar Elhachemi

In the literature, some works deal with the two-machine flow shop scheduling problem under availability constraints. Most of them consider those constraints only for one machine at a time and also with limited unavailability periods. In this work, we were interested by the unlimited periodic and…

Observer-based consensus for second-order multi-agent systems with arbitrary asynchronous and aperiodic sampling periods

Tomas Menard, Emmanuel Moulay, Patrick Coirault, Michael Defoort

A novel distributed consensus protocol, where only sampled position information is exchanged between neighboring agents, is designed for second-order multi-agent systems under a directed communication topology. This protocol allows to reach the consensus for asynchronous and aperiodic sampling…

Model free active flow control of a simplified car model

Baptiste Plumejeau, Sebastien Delprat, Laurent Keirsbulck

A model free control (MFC) approach is presented and used to symmetrize the unstable wake flow of a simplified car model named Ahmed body. Such unstable phenomena with regards to the space-time evolution of the low pressure wake vortex core, is known to increase the global drag of square back…

Framework of models for selecting manufacturing processes and associated parameters for surface topographies

Benoit Rosa, Maxence Bigerelle, Antoine Brient, Serge Samper

Choosing appropriate manufacturing processes to create functional surfaces is a challenging issue for some industrials. A specific surface finish can be obtained by different manufacturing processes, each of them having a different economic impact. Currently, no tool could guarantee the surface…

Conductimetry technique for the measurement of thin liquid film thickness between two solid surfaces in relative motion: hydrodynamic lubrication

Fethi Aloui, Lamia Gaied, Wafik Abassi, Marc Lippert, Maxence Bigerelle

This paper presents an approach for the measurement of a liquid film thickness in contact with a rough surface, based on electrical conductance sensor. This type of sensor consists of two electrodes mounted flush on a wall and using an electrolyte solution representing the liquid film. Assessing of…
