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 ... Per saperne di più

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 ... Per saperne di più

COMSOL® Analysis-Led Design of Prototype Coil Program for Bi-2212 Coils

E. Bosque [1], U. Trociewitz [1],
[1] Applied Superconductivity Center - National High Magnetic Field Laboratory, Tallahassee, FL, USA

The National High Magnetic Field Laboratory (NHMFL) strives to push magnet technology to ever higher field strengths. Supported by a unified effort of material research as well as coil research, Bi2Sr2CaCu2O8+δ (Bi 2212) technology shows promise as a high temperature superconductor (HTS) ... Per saperne di più

COMSOL Multiphysics® as a Tool for Biomedical Engineering Students to Harness Physical Processes

J. Bush [1],
[1] Old Dominion University, Norfolk, VA, USA

The field of Biomedical Engineering is expanding at an exponential rate. As we began to unravel clues about our complex biological vessels, we uncovered more questions than answers. Our collective curiosity has led biomedical engineering into a broadening field by study of physiological ... Per saperne di più

Analyzing Electromagnetic Modes of Integrated Busbars Implemented as Printed Circuit Boards (PCB)

A. Pokryvailo [1],
[1] Spellman High Voltage Electronics Corp., Hauppauge, NY, USA

This report addresses design of a PCB intended for use as a busbar integrated with multiple DC-link (rail) capacitors in a high power inverter. The geometry and current ratings are typical of a 50 kW unit operating at 60kHz in an intermittent mode. First, circuit aspects are analyzed. ... Per saperne di più

Analysis of D-Shaped Toroidal Superconductive Coils for Medium Size Fusion Experiment Facility

V. Cocilovo [1],
[1] ENEA Frascati Research Center, Frascati, Italy

The research in magnetic confinement fusion is carried out through electromagnetic machines, with a toroidal geometry, where a hot plasma of heavy hydrogen isotopes (deuterium and tritium) is contained in a vacuum vessel. Due to the very high temperatures reached by the plasma, strong ... Per saperne di più

Using the COMSOL Multiphysics® software for simulation of TEGs for Waste Thermal Energy Harvesting

L. Howard [1], D. Tafone [2], D. Grbovic [1], A. Pollman [1],
[1] Naval Postgraduate School, Monterey, CA, USA
[2] Ramapo College of New Jersey, Mahwah, NJ, USA

Navy systems, such as turbine engines, produce large quantities of thermal energy. This energy is a byproduct of the work produced by the engine during operation and is typically rejected to its surroundings. The temperature difference between the turbines and the ocean is substantial ... Per saperne di più

Using Multiphysics to Quantify Leakage Rates in New and Rehabilitated Sewer and Water Pipes

C. Hansen [1],
[1] Electro Scan Inc., Sacramento, CA, USA

Traditionally, municipal sewer and water agencies have relied on acoustic data loggers and closed-circuit television cameras to inspect pipes for leaks. In addition, the same legacy techniques have been used to certify new and rehabilitated pipes as watertight. Unfortunately, visually ... Per saperne di più
