Innovative Packaging Design for Electronics in Extreme Environments

Brice McPherson

Power electronics appear in many everyday products, including smartphones, electronic car parts, and household objects. Such devices require controlled temperature ranges, switching frequencies, and voltage levels to operate smoothly and reliably. For harsh environments–such as the depths below the earth’s surface where oil is drilled–there is an increasing need to develop electronic ...

Multiphysics Analysis of CO2 Foil Thrust Bearing Characteristics

Treevor Munroe
Knolls Atomic Power Laboratory, Niskayuna, NY

Knolls Atomic Power Laboratory (KAPL) is a research and development facility supporting the United States Naval Nuclear Propulsion Program. KAPL recently collaborated with Bettis Atomic Power Laboratory to test a supercritical carbon dioxide (S-CO2) Brayton power cycle system. The system was designed to operate at high speed and high gas pressure, which means the turbine shaft bearings must ...

Around the Clock Solar Power

ENEL, Rome, Italy

Italian utility ENEL and the Italian National Agency for New Technologies joined together to develop a new kind of Concentrating Solar Power (CSP), using Parabolic Trough CSP to generate electricity during sunny hours as well as under overcast conditions or at night. This new type of CSP plant depends on molten salt as a medium for storing heat in large, well-insulated tanks. Molten salt has ...

Lightning-Proof Wind Turbines

Soren Find Madsen
Global Lightning Protection Services A/S, Lejre, Denmark

Søren Find Madsen, Global Lightning Protection Services A/S, Lejre, Denmark Global Lightning Protection Services A/S (GLPS) is an engineering consultant firm specializing in lightning protection. Their current research involves protecting wind turbines from lightning strikes, which can interfere with the electronic equipment in the housing of the turbines. To analyze optimum design, GLPS ...

Shape Changing Lubricants

Robert Ian Taylor
Shell Global Solutions
Cheshire, UK

Shell Global Solutions UK is conducting research to optimize lubricants for the fuel economy. A problem exists in creating a balance between energy efficient lubricants that decrease friction, and the higher wear created by the thinner oil film in the lower friction lubricant. There are also many points of contact with extremely high pressure, which increases the viscosity of the lubricant, ...

Multiphysics Simulations Enable Development of Fast, Cheap MEMS-Based Bacteria Detector

Yale University
New Haven, CT

Professor Mark Reed and his team at Yale University are using COMSOL Multiphysics to develop a MEMS-based solution for detecting bacteria in blood. Called the aScreen, it will provide analyses speedily, accurately, and cost-effectively. Such a device would greatly help the food industry in improving meat quality and reducing the risk for infections. Current methods take too long for most food ...

The Burning Need for Modeling

Gianluca Argentini
Riello Burners
Legnago, Italy

Riello Burners manufactures high-efficiency low maintenance burners for use in residential and commercial heating applications, as well as in industrial processes. Proper ventilation is crucial for a burner because it maintains appropriate air flow into the combustion head where the flame is located. When designing the fan for any burner, there must be a balance between a configuration which ...

Battery Simulation Propels Electric Cars in China

Dr. Songrui Wang

Tianjin Institute of Power Sources, Tianjin, China

Dr. Songrui Wang is a researcher at The Tianjin Institute of Power Sources, involved in battery testing and evaluation for design recommendations on safety. She analyzes the risk of potential fire hazards associated with lithium ion batteries, which are fast becoming the most popular sort of battery for vehicles, mobile devices, and many other applications. COMSOL Multiphysics was used to ...

Control of Joule Heating Extends Performance and Device Life

Jean-Louis Gelet and Antoine Gerlaud
Mersen, France

Large electrical systems carrying high currents could pose a danger if any of their components, such as fuses and bus bars, fail. In order to increase safety and improve manufacturing, it is necessary to understand the failure mechanisms of those components. One of those components, a bus bar, is made up of a single piece of conducting metal that replaces individual, thick cables when conducting ...

Optimization Slashes Energy Consumption in Silicon-Based MEMS CO2 Detectors

Serge Gidon

CEA, Leti, Minatec, Grenoble, France

CEA-MINATEC is an international center for micro and nano-technologies which is funded by CEA, a French government-funded technological research organization. One of their current projects is developing silicon-based MEMS CO2 sensors that employ optical detection for monitoring adequate building ventilation. For the sensor to function, a filament is heated to a specific temperature so that it ...
