Spatial Resolution Correction for Electrochemical Wall-shear Stress Measurements using Rectangular Sensors

Fawzi Fadla, Rogelio Chovet, Denis Cornu, Marc Lippert, Fethi Aloui, Laurent Keirsbulck

This article is mainly motivated by the growing needs for highly resolved measurements forwall-bounded turbulent flows and aims to proposes a spatial correction coefficient in order toincrease the wall-shear stress sensors accuracy. As it well known for the hot wire anemometry, thefluctuating…

Some improvements for determining the hardness of homogeneous materials from the work-of-indentation

Didier Chicot, Michel Yetna N'Jock, Francine Roudet, Xavier Decoopman, Mariana H. Staia, Eli Saúl Puchi-Cabrera

In this work, the total and plastic hardness of a variety of materials were determined from the work-of-indentation. We show that by taking into account the influence of the tip defect, both the total and plastic hardness have the same values and that the hardness-load dependence is considerably…

Modelling Laminate Failure in Composite Materials for Automotive Applications

David Moncayo, F. Köster, Pedro P Camanho, Daniel Coutellier, S. Hartmann

In order to capture the complexity of material failure it is necessary to understand that the performance of FE models depends on a fair use and a fair modeling of composite materials. Based on previous research works, the prognosis capabilities of the current material definitions in LS-DYNA will…

Finding a stabilizing switching law for switching TS models

Zsofia Lendek, Paula Raica, Jimmy Lauber, Thierry-Marie Guerra

This paper considers the stabilisation of switching nonlinear models by switching between the subsystems. We assume that arbitrary switching between two subsystems is possible once a subsystem has been active for a predefined number of samples. We use a Takagi–Sugeno representation of the models…

Exergy assessment of heat transfer inside a Beta type Stirling engine

Houda Hachem, Ramla Gheith, Fethi Aloui, Sassi Ben Nasrallah, Ibrahim Dincer

This paper presents an assessment of both energy and exergy efficiencies of a Beta Stirling engine prototype with a 30 W capacity as the maximum mechanical power output. Its operating pressure is close to atmospheric pressure, and it supports a maximum hot end temperature of 650 degrees C. The…

Use of the PIV and Electrochemical Techniques to Experimentally Characterize the Couette-Taylor- Poiseuille Flow Instabilities

Wafik Abassi, Fethi Aloui, Sassi Ben Nasrallah, Jack Legrand

The Taylor-Couette problem is a fundamental model in bifurcation theory and hydrodynamic stability. The inner cylinder rotation generates a flow pattern known by a transition to turbulence through a sequence of successive hydrodynamic instabilities. The effect of an imposed axial flow on the…

Prediction of performance of Stirling engine using least squares support machine technique

Mohammad Hossein Ahmadi, Mohammad Ali Ahmadi, Milad Ashouri, Astarei Razie, Roghayeh Ghasempour, Fethi Aloui

Stirling engine is an environmental friendly heat engine which could reduce CO2 emission through combustion process. Output power, shaft torque and brake specific fuel consumption represent the efficiency and robustness of the Stirling engines. The present research tries to determine the three…

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…
