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 ...

Continuous Casting: Optimizing Both Machine and Process with Simulation

N. Grundy
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 ...

Floating on Sound Waves with Acoustic Levitation

K. Suthar, C. Benmore
Argonne, IL, USA

As part of an industry that saves lives on a regular basis, pharmaceutical companies are in need of systems that can be used to deliver high-quality medicines. One method utilizes sound waves generated by an acoustic levitator with foam-coated transducers. Using the acoustic force from the sound waves, chemical particles are suspended between the transducers, where they can be mixed in a ...

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, 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 ...
