Let There Be Light: A Brighter Future for OLEDs - new
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 - new
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 - new
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 - new
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 - new
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 - new
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 ...
Improving Gas Pipeline Squeeze-Off Standards with Numerical Simulation - new
Oren Lever, Energy Delivery & Utilization, Gas Technology Institute, USA
Gas Technology Institute (GTI), a leader in natural gas research, development, and training, investigated industry standards for squeeze-off length in gas pipelines to make pipes more accessible. Squeeze-off is a procedure that involves compressing a pipe to completely stop the flow of gas. The GTI team created a fully parametric time-dependent model using the Structural Mechanics Module and the ...
Multiphysics Software Models Mean Flow-Augmented Acoustics in Rocket Systems - new
Sean R. Fischbach, Marshall Space Flight Center/Jacobs ESSSA Group, MSFC, USA
Historically, difficulties in modeling and predicting combustion instability have led engineers to costly physical testing, or even to scrap the system entirely. Sean Fischbach and the research team at NASA used the COMSOL Multiphysics® software to model chamber gas dynamics and the internal acoustics of rocket systems.
