Thermal Modelling For The Implementation Of An Energetic Efficiency Control System In A Room Of Meetings Of Singular Geometry

M. Martínez, V. Fuster, J. Fernández, and I. Benítez
Instituto Tecnológico de la Energía (ITE), Paterna, Valencia, Spain

The aim of this Project is to obtain a temporary and spatial evolution model of the temperature into a meeting room with the aim to develop an efficient energy mechanism which can improve the air conditioner control system. The project has considered two extremes cases: on the one hand a ... En savoir plus

Optimization of Design Parameters of a Novel MEMS Strain Sensor used for Structural Health Monitoring of Highway Bridges

H. Saboonchi, and D. Ozevin
Civil Engineering Department
University of Illinois at Chicago
Chicago, IL

The novel Micro Electro Mechanical System (MEMS) based Piezoresistive stain sensor is presented in this paper. The main goal of this sensor is to monitor the localized strain in the highway bridges especially near the crack tips. Monitoring the crack growth on the bridges can lead to ... En savoir plus

The Effect of Electrolyte Flow Slots in Tooling Electrodes on Workpiece Surface Finish in Electrochemical Machining

B. Bingham[1]
[1]Oregon State University, Corvallis, OR, USA

Electrochemical machining (ECM) uses electrolysis to precisely remove material at high rates. ECM has many advantages over conventional machining: no tool wear, no induced mechanical or thermal stresses, high removal rates virtually independent of material hardness or strength, and ...

Modelling of SiC Chemical Vapour Infiltration Process Assisted by Microwave Heating

G. Maizza[1] and M. Longhin[1]
[1]Dipartimento di Scienza dei Materiali ed Ingegneria Chimica, Politecnico di Torino, Torino, Italy

The excessive presence of residual SiC matrix inter-fiber pores is often the main cause for the very poor mechanical strength and toughness of SiC/SiC composites manufactured by CVI (Chemical Vapour Infiltration) process. This work presents a micro/macro Microwaveassisted Chemical Vapour ... En savoir plus

Current Density Distribution and Material Removal Behavior on the Graphite/Iron-matrix Interface in Cast Iron Under Pulse Electrochemical Machining Conditions

O. Weber[1], R. Kollmannsperger[2], D. Bähre[2]
[1]Center for Mechatronics and Automatization, Saarbrücken, Germany
[2]Institute of Production Engineering, Saarland University, Saarbrücken, Germany

The Pulse Electrochemical Machining is especially suitable for the precise production of complex geometric contours with high precision and high surface quality demands in workpieces in series manufacturing. During this process, the negative structure of an electrode is copied to the ... En savoir plus

Dynamic Observation of Magnetic Particles in Continuous Flow Devices by Tunneling Magnetoresistance Sensors

A. Weddemann[1], A. Auge[1], F. Wittbracht[1], C. Albon[1], and A. Hütten[1]

[1]Department of Physics, Thin Films and Physics of Nanostructures, Bielefeld University, Bielefeld, Germany

Dynamic measurement of magnetic particles in continuous flow devices is made very difficult by the limitations imposed by the sensors themselves. Thus, certain sensor layouts are restricted to either number sensitive or spatial resolutive measurements of magnetic particles. We ... En savoir plus

Modeling the Adsorption of Ions on Electrodes in a Flow Cell

R Venkataraghavan[1], Tinto Alencherry [1], Naveen A[2]
[1]Unilever R&D Bangalore, Whitefield, Bangalore, India
[2]IISER Pune, Pashan, Pune, Maharashtra, India

Efficient and low cost deionization is a major technology challenge. Energy efficient technologies like Capacitive deionization (CDI) are possible emerging alternatives. In the present work, we simulate charge adsorption in a 2D flow cell to study its dependence on applied potential and ... En savoir plus

Dynamic Crack Propagation in Fiber Reinforced Composites

C. Caruso[1], P. Lonetti[1], and A. Manna[1]

[1]Department of Structural Engineering, University of Calabria, Arcavacata di Rende, CS, Italy

A generalized model to predict dynamic crack propagation in fiber composite structures is proposed. The proposed approach is based on a generalized formulation based on the Fracture Mechanics approach and Moving mesh methodology. Consistently to the Fracture Mechanics, the crack ... En savoir plus

Kinetic Investigation of a Mechanism for Generating Microstructures on Polycrystalline Substrates Using an Electroplating Process

T. Soares[1], H. Mozaffari[2], H. Reinecke[1]
[1]Universität Freiburg, Freiburg im Breisgau, BW, Germany
[2]Hochschule Furtwangen, Tuttlingen, BW, Germany

The purpose of this study is to understand the growth mechanism of copper (Cu) films on a Cu-Zn system substrate with a pre-defined pattern. The pattern was defined by conducting a selective etching process on a two-phase polycrystalline substrate. As a result of this process, there were ... En savoir plus

A Study of Distributed Feed-Back Fiber Laser Sensor for Aeronautical Applications Using COMSOL Multiphysics

I. Lancranjan[1], C. Gavrila[2], S. Miclos[3], and D. Savastru[3]
[1]Advanced Study Centre - National Institute for Aerospace Research Elie Carafoli, Bucharest, Romania
[2]Technical University of Civil Engineering Bucharest, Romania
[3]National Institute R&D of Optoelectronics, INOE 2000, Bucharest, Romania

Distributed Feedback Fiber Laser (DFB-FL) sensors are increasingly used in aeronautical applications. One of the newest such applications consists in detecting the “transition” zone between laminar and turbulent air flow upon the extrados surface of an aircraft wing. In this specific ...
