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 ...

Switching Made Easy

Matthias Richwin,
Leopold Kostal GmbH,
Dortmund, Germany

Modern cars offer a wide range of complex functionality that comes with several design challenges. This story discusses some of the necessary updates to a roof module in a premium car and the charging system of an electric car. The roof module of a particular model houses several components. 90% of the generated heat goes into its printed circuit board (PCB), so temperature control is vital for ...

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 ...

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 ...

Floating on Sound Waves with Acoustic Levitation

K. Suthar, C. Benmore
Argonne, IL, USA

As part of an industry that saves lives on a regular basis, pharmaceutical companies are in need of systems that can be used to deliver high-quality medicines. One method utilizes sound waves generated by an acoustic levitator with foam-coated transducers. Using the acoustic force from the sound waves, chemical particles are suspended between the transducers, where they can be mixed in a ...

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 ...
