Modeling with COMSOL the Interaction Between Subducting Plates and Mantle Flow

J. Rodríguez-González[1], A.M. Negredo[1], P. Petricca[2], and E. Carminati[2][3]

[1]Departamento de Geofísica y Meteorología, Facultad de CC. Físicas, Universidad Complutense de Madrid, Madrid, Spain
[2]Dipartimento di Scienze della Terra, Università di Roma La Sapienza, Roma, Italy
[3]Istituto Geologia Ambientale e Geoingegneria – CNR, Roma, Italy

Subduction processes have great importance as are related to volcanism and earthquake occurrence. Old and cold plates should subduct steeper than younger ones, but the subduction angle is highly variable and does not always correlate with the age of the plates. Some researchers propose a ...

Particle Flow Control by Magnetically Induced Dynamics of Particle Interactions

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

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

In this work, we show that dipolar magnetic coupling can be used to control the particle flow through microfluidic structures without changing the state of motion of the carrier liquid. Also no external magnetic gradient fields are employed; the total external magnetic force applied is ... En savoir plus

A Study into the Acoustic and Vibrational Effects of Carbon Fiber Reinforced Plastic as a Sole Manufacturing Material for Acoustic Guitars

J. O'Donnell[1], G. McRobbie[1]
[1]University of the West of Scotland, Paisley, Scotland, United Kingdom

This study will research a modern design of acoustic guitar by analysis of the vibrational modes. The guitar that will undergo testing has been provided by Emerald Guitars and is solely constructed using Carbon Fiber Reinforced Plastic (CFRP). With the use of COMSOL Multiphysics© the ...

Finite Element Analysis of an Enzymatic Biofuel Cell: The Orientations of a chip inside a blood artery

C. Wang[1], Y. Parikh[1], Y. Song[1], and J. Yang[1]
[1]Mechanical & Materials Science Engineering, Florida International University, Miami, Florida, USA

Output performance of an implantable enzymatic biofuel cell (EBFC) with three- dimensional highly dense micro-electrode arrays has been simulated with a finite element analysis approach. The purpose of this research is to optimize the orientation of this EBFC chip inside a blood artery ... En savoir plus

Modeling a Combined Photovoltaic-Thermal Panel

E. Gutierrez-Miravete[1], B. Fontenault[2]
[1]Rensselaer Polytechnic Institute, Hartford, CT, USA
[2]General Dynamics-Electric Boat, Groton, CT, USA

A novel combined photovoltaic-thermal panel can simultaneously increase the conversion efficiency of the PV cell and utilize some of the excess thermal energy created by the conversion process (see Figure 1). The Conjugate Heat Transfer physics in COMSOL was used to create a two ... En savoir plus

Design and Development, via Prototype Testing and Multiphysics Modelling, of a Thermoelectric Generator (TEG) for Integration in Autonomous Gas Heaters

M. P. Codecasa[1], C. Fanciulli[1], R. Gaddi[2], F. Gomez Paz[3], and F. Passaretti[1]
[1]National Research Council of Italy - IENI Institute, Lecco, Italy
[2]Italkero S.r.l., Modena, Italy
[3]Studio di design Francisco Gomez Paz, Milano, Italy

An autonomous gas-heater for outdoor environments was selected as a test-case for cogeneration in gas-heaters and stoves, permitting installation and operation without need of an electrical network connection. A thermoelectric generator (TEG) was designed, converting part of produced ... En savoir plus

The Effect of a Correlated Surface Roughness and Convection on Heat Conduction

A.F. Emery[1]
[1]Department of Mechanical Engineering, University of Washington, Seattle, Washington, USA

Heat conduction through a slab, 0 ≤ x ≤ W is one dimensional. However, if one of the edges, say x=0, is rough the conduction will be two dimensional. The two dimensionality varies with the correlation length with a maximum at a length approximately 10% of the slab width. ... En savoir plus

Modeling and Simulation of High Permittivity Core-Shell Ferroelectric Polymers for Energy Storage Solutions

N. Badi[1], R. Mekala[1]
[1]University of Houston, Houston, TX, USA

The dielectric properties of ferroelectric PVDF polymer embedded core-shell (Al-Al2o3) nanoparticle is simulated using COMSOL Multiphysics® software. Significant increase in electrical permittivity of the composite at percolation threshold (K = 2800) is achieved when compared to ... En savoir plus

FEM Based Estimation of Biological Interaction Using a Cantilever Array Sensor

S. Logeshkumar, L. Lavanya, G. Anju, and M. Alagappan
PSG College of Technology
Coimbatore
Tamil Nadu, India

In the model silicon nanorods are designed as cantilever array and coated with thin film of aluminum or aluminum nitride, to be characterized, thus, adding a detectable mass and altering the cantilever resistance to bending. The simulated results show that when films of different ... En savoir plus

The Application of Low Temperature Plasma in COMSOL Multiphysics

Cheng-Che (Jerry) Hsu[1]
[1]Department of Chemical Engineering, National Taiwan University, Taipei, Taiwan

Multiphysics simulation was used in this work to model inductively coupled plasmas (ICPs). Developing a model of an ICP is challenging due to the complex relationship between the applied electric field and mixture of chemical species that develops. A preliminary model was developed and ...
