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.
Graphene Paves the Way for Next-Generation Plasmonics - new
Alexander V. Kildishev, Birck Nanotechnology Center, Purdue University, USA
Alexander V. Kildishev, associate professor of electrical and computer engineering, is leading computational nanophotonics efforts at Birck Nanotechnology Center, Purdue University, and combining graphene with plasmonics to bring the material closer to practical optoelectronics applications. Kildishev and his team use simulation tools to design and optimize devices made from graphene. With ...
Simulating Printhead Unimorph Actuators at FUJIFILM Dimatix
Chris Menzel, FUJIFILM Dimatix, USA
FUJIFILM Dimatix, a top producer of commercial inkjet printheads, uses multiphysics simulation to develop MEMS actuators, which their newest ink deposition projects are based on. Chris Menzel, a principal scientist on the research team at FUJIFILM Dimatix, studies printhead actuation to further the design of FUJIFILM's newest unimorph diaphragm actuators. The team used COMSOL Multiphysics® to ...
Increasing Productivity and Revenue with Computational Applications
Jeff Crompton, AltaSim Technologies, OH, USA
HeatSinkSim is a simulation app created by the specialists at AltaSim Technologies that can help optimize heat sink designs for power electronics. This app was developed with the Application Builder in the COMSOL Multiphysics® software and deployed by installing COMSOL Server™ on a cluster. The primary objective of HeatSinkSim is to speed up the delivery of customized heat sink designs while ...
Giving Furniture Testing a Leg Up
Mark Yeoman, Continuum Blue, UK
Chairs must meet quality standards, which requires lengthy and costly testing. To reduce the burden on manufacturers, a test house enlisted Continuum Blue to create a tool for clients to virtually test chair designs. Continuum Blue used COMSOL Multiphysics® to create a model to predict a chair's response to a standard loading test. They used the Application Builder to convert the model into a ...
