Heat Transfer and Phase Changex

Numerical Solution of Nonlinear PDEs Exhibiting Soft Bifurcations

A. Boulbitch [1],
[1] IEE S.A. Luxembourg

This talk communicates a pseudo-dynamic approach to solve nonlinear stationary equations exhibiting soft bifurcations. The procedure consists in passing from the stationary partial differential equation - to an artificially-built pseudo-time dependent one. We construct the latter in ... Mehr lesen

Modeling Approach to Facilitate Thermal Energy Management with Phase Change Materials (PCM)

D. Rubinetti [1], D. A. Weiss [1], A. Chaudhuri [2], D. Kraniotis [2],
[1] Institute of Thermal and Fluid-Engineering, University of Applied Sciences and Arts Northwestern Switzerland
[2] Department of Civil Engineering and Energy Technology, Oslo Metropolitan University, Norway

Thermal energy storage systems receive notable attention within the framework of energy management due to their ability of bridging thermal energy demand and supply, thus leading to an overall efficiency increase. The key component in such systems are materials which convert ... Mehr lesen

Laser-Material Interaction Modeling using the COMSOL Multiphysics® software

E. C. Chevallier [1], V. Bruyère [1], P. Namy [1],
[1] SIMTEC, Grenoble, France

Surface engineering is a key technology used in a wide range of sectors in industry. Among other techniques, it involves adding functionality to a surface. This can be performed by creating a specific topography to a surface using laser texturing. The objective of the work presented in ... Mehr lesen

Elucidating the Mechanisms of Charge and Temperature Modulated Ionic Transport in Nanochannels

G. Zhang [1], Y. Zhao [1],
[1] Department of Biomedical Engineering, University of Kentucky, Lexington, KY, USA

The transport of fluid through nanochannels is of importance in a variety of technological applications, including biological sensing, energy storage and conversion, chemical separation and many others. Synthetic nanofluidic architectures that mimic the gating functions of biological ion ... Mehr lesen

Comprehensive Numerical Modeling of Filamentary RRAM Device

D. Niraula [1], V. Karpov [1],
[1] University of Toledo, Toledo, OH, USA

Resistive random-access memory (RRAM) is a non-volatile memory that operates via resistive switching between the insulating (OFF) and conducting (ON) states, representing the logical ‘0’ and ‘1’ binary states, in response to external bias. Attributes such as high memory density, fast ... Mehr lesen

A Heat Transfer Analysis of the Cochlea During Magnetically-guided Cochlear Implant Surgery

F. Esmailie [1], M. Francoeur [1], T. A. Ameel [1], ,
[1] Department of Mechanical Engineering, University of Utah, Salt Lake City, UT, USA

Approximately 450,000 people worldwide suffering from hearing problems use cochlear implants (http://www.cochlear.com/au/home/connect/cochlear-hearing-ambassador, June 12, 2018). Manual insertion of the cochlear implant during surgery can potentially damage the delicate tissues within ... Mehr lesen

Time-dependent Thermoelectric Switching in Vanadium Oxide

G. Àbel [1], F. Torres [1], M. Kiwi [1],
[1] Universidad de Chile, Santiago, Región Metropolitana, Chile

We report the reversible thermoelectric switching [1, 2, 3] induced by a time dependent and frequency domain electric field (or AC voltage) in a microscopic single contact nano-device based on Gold and Vanadium Oxide, which promises potential applications for future information storage ...

Thermoelectric Generators With Double Cooling And Novel Thermoelectric Materials

D. Buna [1], L. Hohxa [1], D. Tafone [1],
[1] Engineering Physics, School of Theoretical and Applied Science, Ramapo College of New Jersey, Mahwah, NJ, USA

Recent developments (1) in thermal metamaterials that enhance the response of thermoelectric generators (TEG) have revived the interest in TEG research. The COMSOL Multiphysics® software offers the unique opportunity to model TEGs with various cooling systems (air, water, etc) and ... 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

Steady-State and Transient Electrothermal Simulation of Microheater for Gas Sensing

A. N. Radwan [1], M. Mehregany [1],
[1] Case Western Reserve University, Cleveland, OH, USA

Microheaters used for gas sensing applications have been studied analytically and experimentally. Previously reported microheaters at COMSOL® conferences have shed light on microheaters’ thermal properties, optimized geometries and power consumption—all based on steady-state analysis. In ...
