C. Evans, Schrader, Ireland
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 ...

Chip manufacturers have been adhering to Moore’s law, a law stating that the number of transistors that can be economically placed on an integrated circuit doubles every year, since 1965. As the number of transistors increases, however, the process of manufacturing integrated circuit, called photolithography, becomes more difficult. Each device requires approximately 200 cleaning and ...
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 ...
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 ...

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 ...
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 ...
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 ...

Dielectrophoresis (DEP) is a method of patterning cells and particles used in medical, electronics, and energy applications. When an electric field is applied to an array of cells or dielectric particles suspended in a medium, they become polarized, causing movement that reorganizes the particles. This is an efficient way to assemble materials layer by layer at the nanoscale, and is sometimes ...
From power generation to its distribution to end users, power transformers and shunt reactors are used throughout the electrical grid for voltage conversion and to absorb reactive power. At Siemens Brazil in Jundiai, São Paulo, designers are using multiphysics simulation to verify that grid-integrated transformers and shunt reactors can handle increasing power demands without overheating in ...
HORIBA Medical, France
Hematology analysis, the analysis of a blood sample to determine a variety of hematological parameters, is a major factor in diagnostic and treatment decisions for blood diseases. Accurate blood analysis requires counting and sorting different cells in a sample to measure their sizes and distributions. HORIBA Medical, a company that supplies medical diagnostic equipment, uses COMSOL Multiphysics ...
