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 ...

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 ... Read More

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 ...

Simulating Specular Reflectance in Solar Cleaning Films using the Particle Tracing Module of the COMSOL Multiphysics® Software and LiveLink™ for MATLAB®

J. Bone [1], C. Morales [1], R. Eriksen [1], M. Mazumder [1], M. Horenstein [1],
[1] Electrical and Computer Engineering, Boston University, Boston, MA, USA

One of the obstacles preventing photovoltaic and concentrated solar power technologies from scaling up to meet increasing electricity demands is the inevitable dust accumulation on the optical surfaces of solar collectors. The ideal location for solar power is arid environments due to ... Read More

Several Hydrodynamic Instabilities Illustrated Using the COMSOL Multiphysics® Software

C. F. Ivory [1],
[1] Washington State University, Pullman, WA, USA

The COMSOL Multiphysics® software has proved itself an invaluable tool for teaching "Transport Phenomena" to graduate and undergraduate engineers. In particular, the software allows us to visualize and explore solutions well beyond what students could do with pencil and paper. For ... Read More

Multiphysics Simulation of an Ultrasonic Piezoelectric Motor

P. Carvalho [1], C. Nycz [1], K. Gandomi [1], G. Fischer [1],
[1] Worcester Polytechnic Institute, Worcester, MA, USA

Operation in strong magnetic fields, vacuum or high precision positioning has often surpassed the limits of traditional actuators. Piezoelectric motors provide a suitable alternative in these applications where non-ferromagnetic based construction or low inertia may be required. We ... Read More

Modeling the Electric Double Layer in Finite Electrolyte Solutions

J. C. Woehl [1],
[1] University of Wisconsin - Milwaukee, Milwaukee, WI, USA

While electric double layers play a crucial role in many biophysical processes involving charged molecular species (such as proteins and DNA), they are often a limiting factor in technological applications where charged conductors are brought in contact with electrolyte solutions. ... Read More

Magnetic Control of Deformation of a Ferrofluid Droplet in Simple Shear Flow

C. Wang [1], M. R. Hassan [1],
[1] Department of Mechanical and Aerospace Engineering, Missouri University of Science and Technology, Rolla, MO, USA

This study investigates the effect of uniform magnetic field on the deformation of a ferrofluid droplet in a two dimensional (2D) simple shear flow by means of numerical simulation. The magnetic field is applied in a perpendicular direction to the flow direction. A numerical scheme ... Read More

Load Noise Calculation of a Three-Phase Power Transformer

C. S. Lin [1],
[1] Pitotech. Co Ltd., Changhua City, Changhua, Taiwan

Vibrations and noise of high power transformers have attracted considerable experimental and theoretical interests over last few years [1, 2]. For such transformers operating under high voltage (~ 100 kV) and power (~ 100 MVA), noise generated is significantly attributed to load noise ... Read More
