Simulating the Release Mechanism in Drug-Eluting Stents

T. Schauer, I. Guler
Boston Scientific Corporation, MN, USA

Stent insertion through the coronary artery is a common procedure used to treat restricted blood flow to the heart caused by stenosis. Following the procedure, restenosis may occur due to excessive tissue growth around the stent. Researchers at Boston Scientific are using multiphysics simulation to better understand how drug-eluting stents prevent tissue regrowth and further improve their design ...

Simulation Helps Improve Atmosphere Revitalization Systems for Manned Spacecraft

J. Knox, R. Coker
NASA Marshall Space Flight Center, AL, USA

To ensure astronaut safety on space missions, it is necessary to routinely revitalize the atmosphere in manned spacecraft. Jim Knox, Rob Coker, and a team of engineers at the NASA Marshall Space Flight Center have developed a water-saving system called an Isothermal Bulk Dessicant (IBD). The IBD is used to collect water from the atmosphere for re-use. It consists of packed beds lined with silica ...

Nanoresonators Get New Tools for Their Characterization

J. Yang, M. Perrin, P. Lalanne
CNRS, France

Nanoresonators, or optical nanoantennas, manage the concentration, radiation, and absorption of light at the nanometer scale and show stunning promise for future improvements to technology, such as sensors, computers, and other electronics. However, the ways that these devices scatter light and interact with their surrounding environment are not well understood, nor are the electromagnetic ...

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 ...
