S. Yushanov, J. Crompton, and K. C. Koppenhoefer, Altasim Technologies, OH, USA
When electromagnetic waves propagate through matter, they interact with inhomogeneities and particles that can locally disrupt the electron distribution, causing electromagnetic radiation and scattering. One mathematical model used to describe the scattering of electromagnetic waves is called Mie scattering, which provides a general solution independent of particle size. Examples of phenomena ...

Built-in tire pressure sensors need to be able to withstand the wear and tear of working within a car’s tire rim. Their design needs to be optimized for both sensitivity and strength. Schrader Electronics built a sensor that works accurately and lasts while operating on a moving tire's rim. They used the Structural Mechanics Module and CAD Import Module of COMSOL Multiphysics to optimize their ...
Doubling Beam Intensity Unlocks Rare Opportunities for Discovery at Fermi National Accelerator Laboratory
M. A. Hassan, T. Khabiboulline, J. Reid
Fermilab, IL, USA
Behind the discovery of the most fundamental and rare physical processes within our universe is powerful technology such as the particle accelerators in use today at Fermilab. For over 40 years, one particle accelerator in particular -- the Booster synchrotron -- has been instrumental in providing high-intensity proton beams for particle physics experiments at the lab. A highly coordinated ...
Researching a New Fuel for the HFIR: Advancements at ORNL Require Multiphysics Simulation to Support Safety and Reliability
F. Curtis, J.D. Freels
Oak Ridge National Lab, TN, USA
In response to the increasing awareness of the risks associated with the proliferation of nuclear materials, the Global Threat Reduction initiative has called for research reactors currently using highly enriched uranium (HEU) fuel to be converted to low-enriched uranium (LEU) fuel. The High Flux Isotope Reactor (HFIR) located at Oak Ridge National Laboratory (ORNL) is one such reactor that uses ...
Boeing Simulates Thermal Expansion in Composites with Expanded Metal Foil for Lightning Protection of Aircraft Structures
J. Morgan, R. Greegor, P. Ackerman, Q. Le
Boeing, WA, USA
Carbon fiber composites are used extensively throughout the body of modern aircraft, such as the Boeing 787 Dreamliner, because of their exceptional strength and light weight. Expanded metal foil (EMF) is added to the composite structure layup as a protective measure to dissipate the extreme heat and current generated by a lightning strike. Engineers at Boeing Research and Technology (BR&T) are ...
SMS Concast, Switzerland
The process of continuous casting has transformed steel production, saving valuable resources while improving steel quality and process efficiency. Continuous casting involves carrying molten refined steel to a caster. There, water-cooled copper molds are used to form steel strands that are cut and then cooled. High-quality steel production requires minimizing the presence of non-metals in the ...

When medical professionals transport vaccines, their cargo needs to be kept at a cool temperature. This limits their ability to travel to regions where there is not enough electricity. Intellectual Ventures’ Global Good program designed a thermos-like container that is powered by ice and keeps vaccines cool for long periods of time. They used COMSOL Multiphysics and its Heat Transfer Module and ...
Human activity steals oxygen from natural water sources such as lakes and this oxygen-deficient water often contains high levels of toxic substances such as metals and organic material. Thus the number of lakes that can be used as a source of water is reduced, straining the available resources and creating a need for water-treatment plants of water which can have negative impacts when powered ...
