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 ...

Innovative Thermal Insulation Techniques Bring Vaccines to the Developing World

D. Gasperino, O. Yildirim
Intellectual Ventures, WA, USA

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 ...

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 effort ...

Scattering of Electromagnetic Waves by Particles

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 ...

Optimized Induction Heating Techniques Improve Manufacturing Processes

I. Jain,
Tata Steel, India

Induction heating has become a valuable tool used by the steel industry for manufacturing various metal products. The process provides more precise heating control, uses less energy, and offers better quality assurance and reliability than traditional production processes. Tata Steel, one of the top ten steel companies worldwide, is using multiphysics simulation to analyze the electromagnetic, ...

Optimizing Built-in Tire Pressure Monitoring Sensors

C. Evans, Schrader Electronics, 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 ...

Modeling Helps Improve Safety in the Production of Teflon

Martin Beckmann-Kluge & Fabio Ferrero

BAM German Federal Institute for Materials Research & Testing, Berlin, Germany

BAM German Federal Institute for Materials Research & Testing in Berlin promotes industrial development by providing research and consultation on materials technology and chemical engineering. Their recent work has been in analyzing the process by which highly flammable TFE gas is converted into a solid called PTFE (polytetrafluoroethylene), or the non-stick coating commonly known as Teflon. ...

Innovative Packaging Design for Electronics in Extreme Environments

Brice McPherson

Power electronics appear in many everyday products, including smartphones, electronic car parts, and household objects. Such devices require controlled temperature ranges, switching frequencies, and voltage levels to operate smoothly and reliably. For harsh environments, such as the depths below the earth’s surface where oil is drilled, there is an increasing need to develop electronic systems ...

How Reclosers Ensure a Steady Supply of Power: It’s All in the Magnet

O. Craciun, and colleagues
Ladenburgh, Germany

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 ...

Pushing the Limits of Chip Density

Derek Bassett and Michael Carcasi
Tokyo Electron America
Austin, TX

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 ...
