Sound Navigation and Ranging (SoNaR, more commonly written in all lowercase as “sonar”) technology can be used for investigating and communicating underwater. To improve the sonar system, you need to optimize the design at a component level. A major component of sonar is the electro-acoustic transducer.

Wind turbine noise is a (hotly disputed) topic that we’ve mentioned on the blog before. While research into noise production by wind farms is still being debated among researchers, one way we’ve found to overcome these noisy turbine troubles is to place turbines offshore where they can’t be heard and, conveniently, high winds with more regularity make energy production more effective. However, a question that comes to mind is: What impact do offshore wind farms have on marine life?

The Passive Vaccine Storage Device (PVSD) is a highly advanced container that combines ingenuity and insulation technology to empower aid workers delivering vaccines to the toughest-to-reach corners of the globe. Designed as a prototype that improves upon earlier models of vaccine transportation devices, this compact apparatus was developed with all the necessary steps: careful planning, simulation, and testing.

One of the main issues with high-power electrical devices is thermal management. Together with BLOCK Transformatoren, we created a model using COMSOL Multiphysics simulation software that encompasses all of the important details when modeling heating of high-power electrical devices. To do so, we had to utilize high performance computing (HPC) with hybrid modeling. Here, we will discuss how to approach this real-life task with the COMSOL software.

It’s likely that you’ve heard or read about many of the exciting discoveries in particle physics research at Fermilab. Powerful particle accelerators, including the Booster synchrotron with its unique ferrite-tuned RF cavities, consistently bring the lab to the forefront of discovery. Upgrading the 40-year-old Booster RF cavities will enable them to produce and sustain particle beams at even higher intensities… but will they overheat? Learn how the engineers at Fermilab address this important design challenge.

Cardiovascular disease is a condition where the arteries in the heart are blocked by plaque. Narrowed arteries can restrict blood flow and cause chest pain and shortness of breath. Bare metal stents can be used to resolve the problem, but excessive tissue can grow over them and narrow the artery again (a process called restenosis). Engineers at Boston Scientific are using simulation to understand the release mechanisms in drug-eluting stents, which can be used to prevent this excess cell growth.

When you lose power at home, you may use a shaker flashlight to navigate about your house. This type of flashlight relies on voltage produced by electromagnetic induction in order to be powered. How much voltage can one of these flashlights produce, do you think? Here, we find out through computation, using the AC/DC Module.

If you are searching for a tutorial on how to model a miniaturized 3D electromechanics problem, then look no further. We have just published an updated version of our video tutorial on how to simulate a capacitive pressure sensor. COMSOL Multiphysics version 4.4 and the MEMS Module are used to simulate the electrostatic, structural, and thermal physics that occur.

The Beckham and Maradona curl obtained with the inside of the soccer cleat (football boot), and the curl by Eder, Nelinho, and Roberto Carlos with the outside of the cleat, is due to the Magnus effect. The effect is named after the scientist who first observed it in a laboratory in the 1850s. The Magnus effect explains the side-force on a sphere that is both rotating and moving forward. Here, we use it to analyze the World Cup™ match ball.
