Multiphysics Analysis of a Burning Candle

Luke T. Gritter, Sergei Yushanov, Jeffrey S. Crompton, and Kyle C. Koppenhoefer

AltaSim Technologies, Columbus, Ohio

Using COMSOL Multiphysics, AltaSim Technologies were able to predict the temperature distribution and flow pattern of a burning flame during steady state candle burning. In a burning candle, local temperatures in the flame exceed 1400 °C. The heat transfer would include radiation, conduction, and convection components while the low melting point of the candle wax would cause a local phase ...

The Science of Water Screening

Ehrich Shaw
Johnson Screens
New Brighton, MN

Johnson Screens® are the manufacturers of steel screens that impede debris from lakes and rivers from entering pipes and valves that will utilize the water. Their task is to provide application-specific screens that must be customized to the environment they are operating in. Often this means taking into account the characteristics of the debris they are to remove, the depth at which the screen ...

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 ...

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 ...

A Smooth Optical Surface in Minutes

Anthony Beaucamp
Zeeko Ltd
Leicestershire, UK

Zeeko Ltd is a technology company that manufactures corrective polishing machines for optics and other surfaces. They are presently researching fluid jet polishing (FJP), which pumps a mixture of water and abrasive particles through a nozzle onto a work piece. Unfortunately, FJP tends to introduce waveforms on to the polished surfaces, which in turn causes serious problems with optics. It is ...

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 ...

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 ?Screen, 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 ...

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 ...
