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 ...

Thermal Characterization of an Electronic Device with a Custom App

Giuseppe Petrone, BE CAE & Test, Italy

BE CAE & Test, a COMSOL Certified Consultant, created a thermal model of a surface-mount device for a client and converted it into a simulation app with the Application Builder in COMSOL Multiphysics®, providing an interactive deliverable that could be used to investigate the system. Their clients are pleased to use an interactive tool with which they can investigate their system. In the ...

Multiphysics Analysis Helps Preserve the Past

Jos van Schijndel, CompuToolAble and Eindhoven University of Technology, Netherlands

Jos van Schijndel is the founder of Netherlands-based consulting firm CompuToolAble and assistant professor at Eindhoven University of Technology, Netherlands, where he specializes in the numerical modeling of the physics that affect building performance. He uses simulation apps with his corporate clients and as a teaching aid. Apps offer an easy way for an end user who has never used ...

Addressing Oil Spill Cleanup Using Hydrophobic Meshes

Jorge Molinero, Amphos 21, Spain

Engineers at Amphos 21 tested a new solution for different oil spill scenarios, hydrophobic meshes, with numerical simulation. The meshes are made of steel or copper and a hydrophobic polymer coating that filters the oil from the water. Using COMSOL Multiphysics® software, they modeled the mesh as a porous medium coupled with two-phase flow to calculate the oil saturation level, flux rates for ...

Shake, Rattle, and Roll

Finn Løvholt, Norwegian Geotechnical Institute (NGI), Norway

The Norwegian Technical Institute (NGI) is an international center for research and consulting that investigates the generation of building vibration due to infrasound. They aim to recommend countermeasures to mitigate low-frequency sound waves at levels of sensitivity, intrusion, and danger for humans. Researchers created a COMSOL Multiphysics® model that captures low-frequency sound waves ...
