Modeling Spectral Emission Phenomena in Beryllium Plasma Using COMSOL Multiphysics

C. Gavrila[1], C. P. Lungu[2], and I. Gruia[3]
[1]Technical University of Civil Engineering Bucharest, Romania
[2]National Institute for Laser, Plasma and Radiation Physics, Bucharest, Romania
[3]University of Bucharest, Faculty of Physics, Bucharest, Romania

The purpose of this paper is to present a numerical modeling of plasma phenomena in beryllium emissions using COMSOL Multiphysics software. The Beryllium films were deposited on mirror polished fine grain graphite substrates using the Thermionic Vacuum Arc (TVA) technology available at ... Read More

A Multiscale-Multiphysics Model for Axon Pathfinding Simulation, the Example of the Olfactory System

G. Naldi[1], G. Aletti[1], P. Causin[1]
[1]Dipartimento di Matematica ‘F. Enriques’, Università degli Studi di Milano, Milano, Italy

In the developing embryo, neurons form connections by projecting axons to appropriate target areas. The projection process includes neurite elongation, resulting from the assembly of new cytoskeletal material at the free end of the axon, a complex cascade of steering decisions, driven by ...

Modeling Integrated Thermoelectric Generator-Photovoltaic Thermal (TEG-PVT) System

R. Kiflemariam[1], M. Almas[1], C. Lin[1]
[1]Department of Mechanical & Materials Engineering, Florida International University, Miami, FL, USA

2D steady state heat conduction-electric current model was created in COMSOL Multiphysics® software to study the performance of thermoelectric generator-photovoltaic-thermal (TEG-PVT) system. Four different cases were studied in the paper. In case 1, PV cells without concentrator was ... Read More

High-Frequency Electromagnetic Heating: 3D Model for Petroleum Production Applications

S. Cambon[1], I. Bogdanov[1]
[1]CHLOE, Pau, France

Oil production industry investigates new methods to improve oil extraction from natural rocks. Since long time the dedicated simulation software has been used to better understand the behaviour and predict the production from oil reservoirs depending on the developed technologies. Modern ...

Simulation of a Heated Tool System for Jet Electrochemical Machining

M. Hackert[1], G. Meichsner[2], and A. Schubert[1][2]

[1]Chair Micromanufacturing Technology, Faculty of Mechanical Engineering, Chemnitz University of Technology, Chemnitz, Germany
[2]Fraunhofer Institute for Machine Tools and Forming Technology, Chemnitz, Germany

Jet Electrochemical Machining (Jet-ECM) is an unconventional procedure using localized anodic dissolution for micromachining. An increasing of the electrolyte temperature will lead to an increase of the electrical conductivity of the electrolyte by about 30% and to a reduction of the ... Read More

Simulation of Constant-Volume Droplet Generators for Parallelization Purposes

D. Conchouso [1], A. Arevalo [1], D. Castro [1], Y. Ying [1], I. G. Foulds [2]
[1] King Abdullah University of Science and Technology, Thuwal, Makkah, Saudi Arabia
[2] School of Engineering, University of British Columbia - Okanagan, Vancouver, BC, Canada

To maintain same droplet size across parallel devices, new break-up strategies based on geometry are been studied. In this work, we model a geometrically-set droplet generator, in which the droplet break-up occurs by a block and break mechanism. In other words when the disperse phase ... Read More

Calculating and Observing Opto-Mechanically Induced Surface Acoustic Waves in a Silica Whispering Gallery Microresonator

J. Zehnpfennig
Photonics Research Center
United States Military Academy
West Point, NY

Here we calculate opto-mechanically induced Surface Acoustic Waves upon a silica microresonator using COMSOL. Using conservation of momentum, we show both analytically and numerically that the photonphonon interaction within the resonator cavity causes a moving train of electrodes - a ... Read More

Poroelastic Models of Stress Diffusion and Fault Re-Activation in Underground Injection

R. Nopper[1], J. Clark[2], C. Miller[1]
[1]DuPont Company, Wilmington, DE, USA
[2]DuPont Company, Beaumont, TX, USA

Stress and failure in the earth have long been observed to couple to hydrogeology. Poroelastic models, introduced by soil scientists, can account for strong two-way coupling between porous crustal rock formations and their pore fluids. Current efforts to provide new energy resources ... Read More

Oxidation of Metallic Nanoparticles

A. Auge[1], A. Weddemann[1], F. Wittbracht[1], B. Vogel[1], and A. Hütten[1]

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

The oxidation behavior of metallic nanoparticles is investigated in respect to material parameters like Mott potential, defects on the microstructure and oxide volume increase per ionic defect. An emphasis is laid on magnetic nanoparticles where the degree of oxidation can be measured ... Read More

Thermal Simulation and Package Investigation of Wireless Gas Sensors

A. Paoli[1], L. Seminara[2], D.D. Caviglia[1], A. Garibbo[2], and M. Valle[1]

[1]Department of Biophysical and Electronic Engineering, University of Genova, Genova, Italy
[2]SELEX Communications S.p.A., Genova, Italy

Gas sensor arrays based on metal oxides operating at high temperature are commonly used in many application fields. They can operate on different principles and each sensor may show very different responses to the individual gases in the environment. Data coming from the array can be ... Read More
