Negative Ion Beams and Secondary Beams

M. Cavenago[1], P. Veltri[2], E. Gazza[2], G. Serianni[2], and P. Agostinetti[2]
[1]INFN-LNL, Legnaro, Padova, Italy
[2]Consorzio RFX, Padova, Italy

The development of powerful negative ion sources requires precise and versatile simulation tools to predict the emittance of the extracted ion beams and the heat load on the electrodes. A first tool is a determination of the plasma beam interface which is accomplished by a set of macro ... Read More

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 ... Read More

Effects Of The Microstructure Of Fibrous Media On Their Acoustic Properties

C. Peyrega, and D. Jeulin
Center of Mathematical Morphology, Mines ParisTech, Fontainebleau, France

This study is a part of the Silent Wall ANR project, to which the Center of Mathematical Morphology is associated. Its main objective is to build an acoustical and thermal insulating system for buildings, composed of fibrous materials. The material is composed of two phases: the fibrous ... Read More

An MHD Modeling of High-Temperature SiC Solution Growth

F. Mercier[1], D. Chaussende[1], J.M. Dedulle[1,2] and J. Lefebure[1]
[1]Laboratoire des Matériaux et du Génie Physique (LMGP), Grenoble INP - CNRS, France
[2]IRIS Technologies, Grenoble, France

Despite its real advantages compare to seeded sublimation growth, SiC solution growth has never given convincing results. The difficulty of stabilizing the growth front, and thus avoiding any polycrystal formation results from a poor description and understanding of the coupled phenomena ... Read More

Evaluation of Tensile Modulus of Carbon Nanotube Bundle Based Composite with Interface Using Finite Element Method

M. S. Islam, F. O. Riktan, S. C. Chowdhury, M. M. R. Chowdhury, and S. Ahmed
Bangladesh University of Engineering & Technology (BUET)
Dhaka, Bangladesh

Carbon Nanotubes (CNTs) have remarkable mechanical, thermal and electrical properties. The properties of CNTs depend on atomic arrangement (how the sheets of graphite are rolled), the diameter and length of the tubes and morphology of nanostructure. In this paper effective elastic ... Read More

Study of Gas Dynamics in the Heat-accumulation Stoves

P. Scotton, and D. Rossi
Dipartimento di geoscienze
Università di Padova
Padova, Italy

The paper aims to clarify some aspects of the gases hydro-dynamics within the twisted conduct of heat accumulation stoves (ceramic-refractory stoves) downstream the combustion chamber. Both Comsol laminar and k-e turbulent models have been used in case of straight and curved pipes with ... Read More

Analysis of Electroosmotic Flow of Power-law Fluids in a Microchannel(1D)

K. SriNithin[1]
[1]IIT Kharagpur, Kharagpur, West Bengal, India

Electroosmotic flow of power-law fluids in a slit channel(1D) is analyzed. The governing equations are the Poisson–Boltzmann equation, the Cauchy momentum equation, Generalized Smoluchowski equation and the continuity equation are used to get shear stress, dynamic viscosity, and velocity ...

3D Simulations of an Injection Test Done Into an Unsaturated Porous and Fractured Limestone

A. Thoraval[1], Y. Guglielmi[2], F. Cappa[3]
[1]INERIS, Nancy, France
[2]CEREGE, Aix-en-Provence, France
[3]GEOAZUR, Valbonne, France

We have developed a numerical model to represent the effect of injection test in unsaturated porous and fractured rock mass. The test was conducted at the LSBB (Laboratoire Souterrain à Bas Bruit) site close to Rustrel, Vaucluse, France in the field of the French ANR project called “HPPP ... Read More

Modeling of Lead-acid Flow Battery

M. N. Nandanwar[1], S. K. Gupta[1]
[1]Indian Institute of Science, Bangalore, India

Failure of conventional lead-acid battery is attributed to degradation of solid active mass (PbO2 and PbSO4 ). A number of research efforts are underway worldwide to overcome degradation of active mass to improve the cycle life of lead-acid batteries. Soluble lead-acid flow battery ... Read More
