Numerical simulation of the transient aerodynamic phenomena induced by passing manoeuvres

David Uystepruyst, Siniša Krajnović

Several three-dimensional Unsteady Reynolds-Averaged Navier-Stokes (URANS) simulations of the passing generic vehicles (Ahmed bodies) are presented. The relative motion of vehicles was obtained using a combination of deforming and sliding computational grids. Two different vehicle bodies were…

The ability of precision hard turning to increase rolling contact fatigue life

Nabil Jouini, Philippe Revel, P.-E. Mazeran, Maxence Bigerelle

In this paper, precision hard turning is proposed for the finishing of the AISI 52100 bearing components to improve rolling contact fatigue life. This finishing process induces a homogenous microstructure at surface and subsurface layers. Fatigue life tests performed on a twin-disk machine show…

3D transient model of vapour chamber: effect of nanofluids on its performance

Hamdy Hassan, Souad Harmand

This paper presents three-dimensional transient model for vapour chamber (flat heat pipe) and the effect of nanofluids on its performance. The vapour chamber consists of two copper plates, two copper/water wick regions and a vapour region sandwiched between the two wick regions. The numerical model…

An expert system to characterise the surfaces morphological properties according to their tribological functionalities: The relevance of a pair of roughness parameters

Maxence Bigerelle, D. Najjar, T. Mathia, Alain Iost, Thierry Coorevits, K. Anselme

Knowing that a surface or profile can be characterized by numerous roughness parameters, the objective of this investigation was to present a methodology which aims to determine quantitatively and without preconceived opinion the most relevant pair of roughness parameters that describe an abraded…

Product-driven control: concept, literature review and future trends

André Thomas, Damien Trentesaux

This chapter focuses on the concept of "product-driven control". First, this concept is introduced and the expected advantages and the problems to be solved are described. A brief but representative state of the art is presented. Several product-driven control applications in different…

Quantification of first contact detection errors on hardness and indentation size effect measurements

Julie Marteau, Maxence Bigerelle, Y. Xia, P.-E. Mazeran, Salima Bouvier

A new method is proposed for the quantification of macroscopic hardness and indentation size effect. This method is based on the simultaneous treatment of several nanoindentation loading curves which are located according to the gap between their shape and the one predicted by the Bernhardt law. By…

Evaluation de requêtes mobiles par composition dynamique de services, Processing mobile queries using dynamic composition of services

Marie Thilliez, Mikael Desertot

Cet article présente une solution pour l’évaluation de requêtes en environnements mobiles, en particulier de requêtes dépendantes de la localisation. Cette solution est basée sur une plateforme orientée services. L’utilisation d’une telle plateforme facilite d’une part, l’évaluation de requêtes…, This paper describes a solution to evaluate queries in mobile environments, specially location queries. This solution is based on a service oriented framework. On the one hand, the use of a such framework facilitates the evaluation of multi-scale queries based on the querying of different data…
