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

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

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 ...

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

Acoustic Wave Propagation in Water Filled Buried Polyethylene Pipes

T. Graf[1], T. Gisler[1], P. Sollberger[1], O. Schaelli[1]
[1]School of Engineering and Architecture, Lucerne University, Horw, Switzerland

Axisymmetric acoustic waves propagating along buried water pipes have been investigated by FEM and experimentally. Universal dispersion relations of the fundamental mode were obtained as a function of the standard dimension ratio SDR and of the material surrounding the pipe (soil, air). ... En savoir plus

An Innovative Solution for Water Bottling Using PET

D. Scardigno[1], A. Castellano[1], P. Foti[1], A. Fraddosio[1], S. Marzano[1], M.D. Piccioni[1]
[1]DICAR, Politecnico di Bari, Bari, Italy

Introduction: We study an innovative technology for water bottling using PET, aimed at reducing the thickness of the plastic bottles. The goals are the reduction of the amount of plastic used for a single water bottle, the reduction of the packaging costs and more environmental ... En savoir plus

Heat Flux Predictions for a 3-D Compost Model

M. Teutli [1], Jiménez[1], Lozano[1], Peláez[1], J. Roque[2], and I. González[3]
[1]BUAP, Puebla, Mexico
[2]Universidad Veracruzana, Xalapa, VZ, Mexico
[3]UAM, Mexico City, Mexico

A 3-D model for compost was constructed taking as geometry basis a truncated cone, with dimensions of 4 m radius and 3 m height; in this structure an energy balance is applied for a two phase system (solid-air). Compost energy processes are modeled using COMSOL with a modified heat ... En savoir plus

3-D Finite Element Modeling of Brain Edema: Initial Studies on Intracranial Pressure Using COMSOL Multiphysics^®

X.G. Li[1], H. von Holst[1][2], J. Ho[1], and S. Kleiven[1]

[1]Division of Neuronic Engineering, KTH, Stockholm, Sweden
[2]Department of Clinical Neuroscience, Karolinska Institute, Stockholm, Sweden

Brain edema is one of the most common consequences of serious traumatic brain injuries which is usually accompanied with increased Intracranial Pressure (ICP) due to water content increment. A three dimensional finite element model of brain edema is used to study intracranial pressure in ... En savoir plus

Development of New Blade Profile for Vertical Axis Wind Turbine

Shuya YOSHIOKA[1]

[1]Ritsumeikan University, Kyoto, Kyoto, Japan

Vertical axis wind turbine has low rotation performance compared with that of horizontal axis wind turbine. This study proposes a new blade shape for vertical axis wind turbine effective for wide range of wind speed. Results obtained from a numerical COMSOL simulation and wind tunnel ... En savoir plus
