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…

Increased antagonist muscle activity in cervical SCI patients suggests altered reciprocal inhibition during elbow contractions

Sylvain Cremoux, David Amarantini, Jessica Tallet, Fabien Dal Maso, Eric Berton

Objective: After spinal cord injury (SCI), the antagonist muscles activation is increased during voluntary contractions and reflex conditioning protocols. This increase can be the result of both muscle atrophy and reciprocal facilitation mechanism. It remains however unclear to what extent…

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…

Turbulent Plane Impinging Jet-Physical Insight and Turbulence Modeling

Mahmoud Charmiyan, Ahmed-Reza Azimian, Laurent Keirsbulck, Ebrahim Shirani, Fethi Aloui

A 3D numerical simulation using large eddy simulation (LES) method is performed for a submerged turbulent water slot jet impinging normally on a flat plate with a nozzle-to-plate distance of 10 jet width and a Reynolds number of 16000 and the results are compared with the existing experimental data…

Experimental study on the stability of an impedance-type force-feedback architecture based on an augmented-state observer for a haptic system under time delay using a LMI approach

Quoc Viet Dang, Laurent Vermeiren, Antoine Dequidt, Michel Dambrine

One of the most important performance measures of a haptic interface may be characterized by its behaviour in the implementation of a virtual wall in terms of the biggest value of the virtual stiffness that still leaves the device stable. This value depends on many factors including time delays and…

Multiscale roughness analysis of engineering surfaces: A comparison of methods for the investigation of functional correlations

Gaëtan Le Goïc, Maxence Bigerelle, Serge Samper, Hugues Favrelière, Maurice Pillet

This study investigates the correlations between the topography of different damaged rough surfaces and process conditions. Several surfaces are measured and compared to determine if they can be discriminated. The analysis is performed by using Gaussian Filtering, Wavelet Transform and a more…
