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 ... Mehr lesen

[4]ITER Organization/Magnet Division, Saint Paul-lez-Durance, France

A successful development of an effective quench detection and protection method for a high temperature superconducting (HTS) coil based on a HTS coated conductor tape lays on a thorough understanding of its slowly propagating, three-dimension (3D) quench behavior. Toward this goal, a 3D ... Mehr lesen

Patch Antenna Model for Unmanned Aerial Vehicle

T. Eppes, I. Milanovic, and S. Thiruvengadam
University of Hartford
West Hartford, CT

Patch antennas are widely used in communications links with unmanned aerial vehicles. Their hemispherical send and receive patterns enable the systems to maintain radio frequency contact over a wide range of vehicular attitudes. A microstrip-fed design offers other attractive features ... Mehr lesen

Assessing the Potential of Ventilated Facades on Reducing a Buildings’ Thermal Load Using Decoupled COMSOL Simulations

J. van Schijndel[1], C. van Dronkelaar[1]
[1]Eindhoven University of Technology, Eindhoven, The Netherlands

Solar radiation is a prominent contributor of energy in buildings, and can be transmitted directly into a building through opaque surfaces, but it can also be absorbed by building components (i.e. walls, roofs etc.). This study discusses the use and effect of ventilated facades, with an ... Mehr lesen

Progress in Numerical Simulation of HIIPER Space Propulsion Device

P. Keutelian[1], A. Krishnamurthy[1], G. Chen[1], B. Ulmen[1], G.H. Miley[1]
[1]University of Illinois at Urbana-Champaign, Champaign, IL, USA

HIIPER is an experimental space propulsion device using a helicon and an IEC as a plasma generation and acceleration stage, respectively. There is an experiment in progress, but for true rapid iteration and to model the performance of the engine, COMSOL is a strong candidate for ... Mehr lesen

Diffusion Modeling in TGA in Context of CO2 Gasification of Char

G. Samdani[1], S. Mahajani[1], A. Ganesh[1], P. Aghalayam[2], R. K. Sapru[3], D. K. Mathur[3]
[1]Department of Chemical Engineering, Indian Institute of Technology Bombay, Mumbai, India
[2]Indian Institute of Technology Madras, Chennai, India
[3]UCG Group, IRS, ONGC, Chankheda, Ahmadabad

The Thermo- Gravimetric Apparatus (TGA) is often used for kinetics determination. In TGA setup, gasification reaction may be limited by the reach (diffusion) of the gasification agent to the internal surfaces of the char particles. In addition to this, after some time, ash is formed ... Mehr lesen

Multiphysics Simulations in Automotive Product Development: Concept and Beyond

Matthias Richwin joined KOSTAL, a worldwide automotive first-tier supplier, in 2003 where he started working on the design of optical sensor systems. In 2007 he took over responsibility for simulation methods in the series product development and since then leads the simulation ... Mehr lesen

Development and Optimization of a Microfluidic Device for Magnetic Field Induced Cell Separation

L. Helmich[1], A. Hütten[1]
[1]Bielefeld University, Bielefeld, Germany

Besides conventional laboratory analysis methods, so called micro-total-analysis devices (µTAS) have gained great interest during the last decades. In this work we demonstrate a mechanism for the separation and selection of medical samples that can be applied within these µTAS devices. ... Mehr lesen

Feed-forward/Feed-backward Mechanical Amplification in the Mouse Cochlea

J. Soons[1,2], C. Steele[2], S. Puria[2]
[1]Lab of Biomedical physics, University of Antwerp, Antwerp, Belgium
[2]Department of Mechanical Engineering, Stanford University, Stanford, USA

Sound vibrations are collected from the external environment by the eardrum and are guided to the basilar membrane in the cochlea. Pressure differences in the two scalae of the cochlea result in a traveling wave on the basilar membrane. The tiny displacements are detected by the ... Mehr lesen
