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…

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…

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…

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…

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…

Improvement of a non energy-consuming system: A gamma Stirling engine

Ramla Gheith, Fethi Aloui, Sassi Ben Nasrallah

In this paper, the classical adiabatic model was chosen. The assumption of perfect gas working fluid was replaced by that of a real gas working fluid. This last assumption was defined by the van der Waals state equation. A Gamma type Stirling engine functioning with a maximum filling pressure of 10…
