Optimizing 3D Printing Techniques with Simulation Apps - new

Borja Lazaro Toralles, MTC, Coventry, UK

3D printing has recently revolutionized manufacturing techniques, influencing countless industries and products. The Manufacturing Technology Centre (MTC), in Coventry, UK, is optimizing the 3D metal printing technique called shaped metal deposition (SMD) for industrial use. Unlike common additive manufacturing technologies, with SMD, a thin layer of molten metal is deposited layer by layer on a ...

Defending Automotive Components Against Corrosive Destruction - new

Daniel Höche, HZG, Germany; Nils Bösch, Daimler AG, Germany

Galvanic corrosion, which occurs when the surfaces of different adjoining metals begin to degrade, costs the automotive industry billions of dollars annually. The reactions of these different metal combinations is influenced by material properties, surface roughness, and joining techniques in the components. Researchers at Helmholtz-Zeentrum Geesthacht (HZG) and Daimler AG created COMSOL ...

Making Biofuel a Cost-Effective, Renewable Source of Energy

Peter Ciesielski, NREL, CO, USA

Pyrolysis is a pre-commercial thermochemical process that converts renewable, plant-based materials such as wood into liquid biofuels. To make pyrolysis a cost-effective method for biofuel conversion, researchers at the National Renewable Energy Laboratory (NREL) are using multiphysics simulation to better understand and optimize the process. Thus far, they have used COMSOL Multiphysics® to ...

Getting Touchy-Feely with Touchscreen Design

Peter Vavaroutsos, Andy Kiernan, Cypress Semiconductor, San Jose, CA

Every time we interact with a smartphone, MP3 device, or video screen in a car, we're relying on capacitive touchscreens to give us information, send messages, or play music. These screens consist of substrates, adhesives, transparent lenses, and indium-tin-oxide (ITO) electrodes that form the stack-ups used in this technology. Touchscreen design varies by application, so each stack-up is ...

The Thermal Management of Li-ion Battery Packs

Michele Gosso & Antonio Fiumara

Fiat Research Center, Orbassano, Italy

At the Fiat Research Center in Italy, Michele Gosso and Antonio Fiumara are working on the development of providing power for electric and hybrid vehicles. The team must combine individual lithium-ion battery pouch cells into battery packs to generate the 350V needed, while providing the packs with sufficient cooling. At the same time, they want to keep the packs as small and light as ...

Simulation-Led Strategy for Corrosion Prevention

S. Qidwai

Corrosion is a widespread concern costing the US billions of dollars annually. For the Navy, specifically, it is the number one maintenance problem. Therefore, at the Naval Research Laboratory (NRL), researchers are developing a method based on multiphysics simulation that will aid material designers in producing corrosion-resistant materials. Their work aims to provide a better understanding of ...

Making Smart Materials Smarter with Multiphysics Simulation

J. Slaughter
ETREMA Products, IA, USA

Smart materials with magnetostrictive behavior are engineered and incorporated in high-precision devices by the designers and researchers at ETREMA Products, Inc. Terfenol-D, in particular, is a giant magnetostrictive material solely manufactured by ETREMA that exhibits the largest deformation of any alloy in response to an applied magnetic field and is integrated into the core of devices such ...

Developing a New Microreactor for Organic Synthesis Using Microwave Heating

W. Lee, K. Jensen

The chemical reactions used to generate solvents and certain pharmaceuticals rely on organic synthesis, a process of combining individual chemicals that can be accelerated through microwave heating. A microreactor system facilitates the direct, localized, and efficient temperature change necessary for successful synthesis. However, a uniform temperature distribution is crucial to the chemical ...

Battling Corrosion in Nuclear Waste Storage Facilities

G. Barbella, P. Geraldini
Sogin, Italy

Nuclear sites in Italy are being decommissioned, leaving questions about how to safely manage and store radioactive waste. Nuclear waste can be stored temporarily in steel drums encased in concrete, but environmental factors must be carefully controlled to prevent corrosion of the steel. It is difficult to constantly monitor the corrosion process, and the relative humidity in the storage area ...

Keeping Cool: SRON Develops Thermal Calibration System for Deep-Space Telescope

C. de Jonge
SRON, Netherlands

Deep-space telescopes require ultrasensitive detectors and calibration to pick up weak far-infrared signals. The SpicA Far-InfraRed Instrument (SAFARI), an infrared camera that will fly aboard the Space Infrared Telescope for Cosmology and Astrophysics (SPICA), has sensors that measure the far-infrared spectrum. The SAFARI system includes a radiation source, needed for calibration, that is so ...
