[1]Massachusetts Institute of Technology, Cambridge, MA
[2]Univeridad Industrial de Santander, Bucaramanga, Colombia
[3]University of Puerto Rico, Mayaguez, Mayaguez, PR

This work analyzes the spin-diffusion dominated explanation for spin-up bulk flows in ferrofluid filled cylinders, with no free surface, subjected to a uniform rotating magnetic field. COMSOL results are compared to experimental results and analytical results. Simulating ferrofluid spin ... Mehr lesen

Planar Geometry Ferrofluid Flows in Spatially Uniform Sinusoidally Time-Varying Magnetic Fields

S. Khushrushahi, A. Weddemann, Y. Kim, and M. Zahn
Massachusetts Institute of Technology
Cambridge, MA

Prior work has analyzed the case of planar Poiseuille ferrofluid flows in planar ducts stressed by uniform sinusoidally applied fields transverse and perpendicular to the duct axis. The coupled linear and angular momentum conservation equations with imposed magnetic flux density, Bx and ... Mehr lesen

Fluid-Structure Interaction Analysis of a Peristaltic Pump

N. Elabbasi, J. Bergstrom, and S. Brown
Veryst Engineering, LLC.
Needham, MA

Peristaltic pumping is an inherently nonlinear multiphysics problem where the deformation of the tube and the pumped fluid are strongly coupled. We used COMSOL Multiphysics to investigate the performance of a 180 degree rotary peristaltic pump with two metallic rollers, and an ... Mehr lesen

Simulation of Quench Propagation in a Double-Helix Superconducting Magnet with COMSOL Multiphysics

P. Masson
Advanced Magnet Lab
Palm Bay, FL

The paper presents the numerical analysis of quench propagation in a DH magnet wound with a commercially available MgB2 wire in a fiber-glass composite matrix and operating at 20 K. The quench is induced by a small heater located on the first layer of the magnet close to the peak field ... Mehr lesen

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 ... Mehr lesen

Dynamic Simulation of Bone Morphogenetic Protein Patterning in a 3D Finite-Element Model of the Danio Rerio Embryo

D. Umulis, and S. Lee
Purdue University
West Lafayette, IN

Zebrafish development of the dorsoventral axis relies on the spatiotemporal distribution of Bone Morphogenetic Protein (BMP) signaling, which is regulated by numerous secreted molecules such as Tolloid, Sizzled, and Chordin. The rich dorsal/ventral patterning network must achieve both ... Mehr lesen

A Flow Induced Vertical Thermoelectric Generator and its Simulation using COMSOL Multiphysics

E. Topal
Micro and Nanotechnology Program
Middle East Technical University
Ankara, Turkey

In this study, a new thermoelectric harvester with fluid flow for increased performance is introduced. The thermoelectric generator is 3D vertical configuration with p- and n-doped Silicon thermolegs. There is water flow between channels integrated through the thermoelectric columns, ... Mehr lesen

Power Transistor Heat Sink Design Trade-offs

T. Eppes, I. Milanovic, and G. Quarshie
University of Hartford
West Hartford, CT

Power transistors require heat sinks to dissipate thermal energy and keep junction temperatures below the recommended limit. The reliability and longevity of any semiconductor device is inversely proportional to the junction temperature. Hence, a significant increase in reliability and ... Mehr lesen

Design of Cooling System for Electronic Devices Using Impinging Jets

P. Lin[1], C. Chang[2], H. Huang[3], and B. Zheng[4]
[1]Mechanical and Aerospace Eng., Rutgers, The State University of New Jersey, Piscataway, NJ
