Transient Process Simulation of Heat Transfer in Laser Beam Welding with an Equivalent Heat Source

A. Artinov [1], M. Bachmann [1], M. Rethmeier [1],
[1] BAM Federal Institute for Material Research and Testing, Berlin, Germany

The Finite Element Method (FEM) has become an established numerical tool used for different academic and industrial purposes. It allows the prediction of weld pool geometry, thermal cycle, final distortion and residual stress field during and after fusion welding. The capability of the ... Mehr lesen

Dispersion Analysis in Coaxial Cables at High Frequencies

S. C. Hegde[1]
[1]VIT University, Vellore, Tamil Nadu, India

The coaxial cable is one of the most commonly used bandwidth limited signal transmission line.Dispersion is a signal distortion phenomenon which arises due to frequency dependence of phase velocity of signal components. This phenomenon was explained through time domain approach by ... Mehr lesen

Motion of Uncharged Particles in Electroosmotic Flow through a Wavy Cylindrical Channel

[1] Bangladesh University of Engineering and Technology, Dhaka Bangladesh

A finite element model is employed to describe the electric potential distribution and electroosmotic flow field inside a wavy cylindrical channel. The model uses coupled Laplace and Poisson-Boltzmann to evaluate the electric potential distribution inside the channel. It also contains ... Mehr lesen

The Effect of Aluminum Content on Convective Flow of Molten Metal Generated by Arc Plasma

Y. T. Cho [1], C. K. Kim [1], H. U. Hong [1],
[1] Changwon National University, Changwon, Gyeongsangnam-do, South Korea

Arc plasma can heat and melt the metal material and flows of molten metal can be affected by several forces such as Lorentz force which is ruled by current, Marangoni force controlled by surface tension, buoyancy force, and arc drag force. Usually, surface tension variation is determined ... Mehr lesen

Numerical Modeling of Cold Crucible Induction Melting

This paper describes a numerical solution method for the simulation of a cold crucible induction melting (CCIM) process involving the coupling of electromagnetic, temperature and turbulent velocity fields. During the CCIM process, the metal charge is contained on a water cooled ... Mehr lesen

A Dual Continuum Model for Groundwater Flow in Karst Aquifers

R. Painter[1], J. Harris[1], T. Byl[1], L. Sharpe[1]
[1]Tennessee State University, Nashville, TN, USA

In karst terrain, the interaction between the fast moving, highly turbulent conduit flow and the slow moving, laminar flow through porous media is largely unknown. Yet the dual nature of the karst system impacts the residence time of solutes in the groundwater supplies of over 25% of the ... Mehr lesen

Design and Analysis of an Electrostatic Precipitator for a Diesel Particulate Filter

S. Manoj[1], R. Giri[1], S. Selvakumar[1]
[1]Rajalakshmi Engineering College, Chennai, Tamil Nadu, India

Gaseous exhaust of different industries contains dust particles of different chemical precipitates that are harmful for the environment. Electrostatic Precipitators are very often used in industries like power plant to filter their gaseous exhaust and to prevent the atmosphere to being ... Mehr lesen

Sound Attenuation by Hearing Aid Earmold Tubing

M. Herring Jensen
Widex A/S, Vaerloese, Denmark

In this study we model the sound attenuation properties of a hearing aid earmold tube. The model includes thermoviscous acoustic effects and it couples structural vibrations to the external acoustic field. Moreover, the finite element domain is coupled at two boundaries with an ... Mehr lesen

Relativistic Quantum Mechanical Wave Functions for Fermion Particles in Electric or Magnetic Fields

A. J. Kalinowski [1],
[1] Consultant / East Lyme, CT, USA

INTRODUCTION: The Dirac equation is employed in particle physics and historically gave the first combined unification of quantum mechanics and relativity theory by introducing a four component wave function Ψi. This wave function described the behavior of fermion type particles (e.g. ... Mehr lesen
