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. ... Mehr lesen

A Multi-phase Heat Transfer Model of Cooling Lava

M. E. Rumpf [1], K. Williams [1], L. Kestay [1],
[1] Astrogeology Science Center, U.S. Geological Survey, Flagstaff, AZ, USA

Field observations suggest that two-phase "heat-pipe" processes are active around magmatic intrusions. We are numerically testing the viability of this process around a volcanic sill, embedded in wet sediment. The model focuses on the heat transported by water in the vapor and liquid ... Mehr lesen

A 3D Simulation of the Diffusion Profile of Brain Derived Neurotrophic Factor in the Inner Ear Using the COMSOL Multiphysics® software

S. Bharadwaj [1], A. Oleksijew [1], J. Fernandez [2], C. Miller [1], K. Coots [1], K. Nella [1], H. T. Chang [1], C. P. Richter [1, 3], J. Kessler [1], A. Matsuoka [1]

Sensorineural hearing loss, which is the most common type of hearing impairment, originates from damaged inner ear nerves. However, this can be treated in many cases by regenerating the synaptic connections between the extant Spiral Ganglion Neurons (SGNs) and transplanted human stem ... Mehr lesen

3D Unsteady CFD Simulation of Seasonal Solar Thermochemical Heat Storage System for Buildings

W. Yaïci [1], E. Entchev [1],
[1] CanmetENERGY Research Centre, Natural Resources Canada, Ottawa, ON, Canada

Solar energy storage has been an extensive research topic among the several thermal energy applications over the past three decades. Thermal energy storage (TES) systems in general, improve the energy efficiency of systems and sustainability of buildings by reducing the mismatch between ... Mehr lesen

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 ... Mehr lesen

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 ... Mehr lesen

Tribological Behavior of Rubber on Glass in Prefilled Syringes

T. Langley [1], E. Gutierrez-Miravete [2], ,
[1] Rensselaer Polytechnic Institute, Troy, NY, USA
[2] Rensselaer at Hartford, Hartford, CT, USA

The primary enclosure of an injected formulation is almost exclusively comprised of a glass container (syringe) and an elastomer closure (i.e. plunger). A failed injection is anything that prevents the full dosage of the drug to be administered, whether that is a glass breakage or ... Mehr lesen

Thermal and Hydraulic Modeling of Road Tunnel Joints

C. H. Klotoé [1], F. Duhaime [1], L. Guizani [1],
[1] Département de Génie de la Construction, École de technologie supérieure, Montréal, QC, Canada

This paper focuses on the use of the COMSOL Multiphysics® software to develop a 2D numerical model of expansion joints for road tunnels. The model was developed using the coefficient form PDEs interface. The model includes water and energy conservation equations. It takes into account ... Mehr lesen
