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 ...

Metamaterials are manufactured, structured materials that they can interact and manipulate wave phenomena such that objects surrounded by metamaterials are shielded from these waves. In the case of light, metamaterials make these objects ‘invisible’. Researchers throughout the world are applying these materials to many different applications. At NASA Glen Research Center, physicists are ...

Simulation-based engineering is the key to shortening time to market for innovations. Intellectual Ventures, in Bellevue, WA, is reaping the benefits of using COMSOL Multiphysics to accelerate their workflow from design study to prototype, and then on to their customers as inventions through various partnerships and licensing programs. Projects where COMSOL has been used include the ...
Rautaruukki Oyj supplies metal-based components and systems to the construction and mechanical engineering industries, where process engineer, Mika Judin, works with optimizing their coating technologies. When coating rolled metal with paint, it is important that the coating be applied such that it is not discolored or damaged, and that it is applied evenly. Heat transfer therefore needs to be ...
Lifescan Scotland is a medical device company that designs and manufactures blood glucose monitoring kits for the global diabetes market. These involve the self-monitoring of blood glucose levels through specialized monitoring systems and test strips that comprise of a plastic substrate, two carbon-based electrodes, a thin dry reagent layer, and a capillary volume where the blood is ...

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 ...
Terres Réfractaires du Boulonnais (TRB), France
To contain splashes and provide protection at plants where metal is fabricated, blast furnace runners need a roof made of cast iron and concrete. Terres Réfractaires Du Boulonnais, a manufacturing company in France, has hundreds of blast furnaces with a short functional lifespan, so engineers need to design roof runners as economically as possible while maintaining overall safety. During the ...
Nofima Norconserv AS,
Nofima is a research group majority owned by the Ministry of Fisheries that performs research and development in aquaculture, fisheries, and the food industry. Nofima collaborated with the Norwegian Centres of Expertise – Culinology and Chef Gunnar Hvarnes to promote halibut through a cooking competition and provided research to ensure a new recipe for a fried halibut fish roll was cooked ...

When a tree branch touches overhead cables and causes a momentary short circuit, your lights may flicker. A device called a recloser ensures that power to your home is not cut off for a longer period. ABB AG, a leading manufacturer in power technology, is working towards designing a more reliable recloser. One objective in this design process was to optimize the size of the permanent magnet ...

The Neuromodulation Group at Lahey Clinic conducted a study based upon spinal cord stimulation (SCS). SCS involves implanting a series of electrodes that apply electric potential to the spine, interfering with pain signaling circuitry. It’s used to alleviate chronic back and leg pain. Although the treatment remains effective for years, the electrodes must be reprogrammed through trial and ...
