Engineering Perfect Puffed Snacks

Tushar Gulati, Ashim Datta, Cornell University, USA

When considering multiphysics processes entailing mass transport, phase transitions, and plastic deformation, your first thought may not be puffed rice. However, the production of puffed rice, like many other types of food, is incredibly complicated and involves multiple interconnected types of physics. Professor Ashim Datta of Cornell University is leading a team to simulate the puffing of ...

How Fast Do Elevated Temperatures Reach the Cell Interior?

Gerd Liebig, Pamina Bohn, NEXT ENERGY EWE Research Centre for Energy Technology, Germany

Lithium-ion batteries, which have a tendency to degrade at high temperatures, must adhere to stringent regulations guaranteeing their ability to withstand operating temperature fluctuations. Researchers at NEXT ENERGY used heat transfer modeling to study whether high welding temperatures can create enough temperature propagation within cells to cause irreversible damage, such as electrolyte ...

Nuclear-Safety-Related SQA Procedure Automation with Custom Applications

James D. Freels, Michael W. Crowell, Oak Ridge National Laboratories, USA

In an environment as highly regulated and potentially dangerous as the nuclear industry, software quality assurance (SQA) compliance standards are rigorous. Part of the compliance process entails verification that local software installations perform as the developer intended. At Oak Ridge National Laboratories (ORNL), COMSOL Multiphysics® is used to explore nuclear fuel conversion. Verification ...

On the Cutting Edge of Hearing Aid Research

Brenno Varanda, Knowles Corporation, Illinois, USA

Nearly 20% of the United States population has some degree of hearing impairment. Despite the relative inconspicuousness and perceived simplicity of hearing aids, their development involves complex, time-consuming, and computationally expensive research. The hearing aid industry is in dire need of a simplified model that can expedite the design process and provide options to consumers quicker. ...

Music to Your Ears: New Transducers Meet Electrostatic Headphones

Brett Marmo, Xi Engineering; Martin Robert, WAT, UK

Electrostatic transducers offer enhanced clarity, less distortion, and a wider bandwidth than transducers in conventional dynamic-driver headphones, but they are only seen as high-end alternatives. The precise manufacturing requirements make electrostatic transducers prohibitively expensive to produce and hinder mainstream commercial viability. Engineers at Xi Engineering and Warwick Audio ...

Manipulate and Control Sound: How Mathematical Modeling Supports Cutting-Edge Acoustic Metamaterials Research

Steve Cummer, Electrical and Computer Engineering Department, Duke University, USA

Researchers at Duke University are using numerical modeling to develop metamaterial structures for acoustic cloaking. Steve Cummer, professor of electrical and computer engineering, explained that the acoustic metamaterial designs are optimized through numerical simulations, which are then translated into modern fabrication techniques and experimentally tested. The COMSOL Multiphysics® software ...

Let There Be Light: A Brighter Future for OLEDs

Leiming Wang, Konica Minolta Laboratory, USA

As the demand for lightweight and flexible electronics continues to increase, so does the demand for lightweight and flexible light sources. Organic LEDs (OLEDs) have garnered tremendous interest because of their inherent elasticity, but suffer from a lack of brightness and efficiency. Researchers at Konica Minolta are working to alleviate these limitations and minimize light lost in their OLED ...

From Nanoantennas to Deep Space Satellites, Electron Emission Enables Efficient Power Generation

Pierfrancesco Zilio, IIT, Italy

Researchers from the Italian Institute of Technology (IIT) and the European Space Agency (ESA) are developing power generation systems based on electron emission, with potential applications in devices meant for outer space or intended to reside within the human body. Several studies were conducted using the COMSOL Multiphysics® software to study the combination of photon-enhanced thermionic ...
