Improving Ultrasound Imaging Systems by Directing Sound Waves
In an earlier blog post, I commented on how acoustic waves are being used in a biomedical setting, to identify malaria in small fluid samples. A more traditional use of piezoelectric devices was written about in the latest COMSOL News. Here, an Italian company, Esaote S.p.A., uses them to produce improved ultrasound imaging systems.
Inventing Makes use of Simulation
One of the interesting stories to come out of the latest COMSOL News concerned a couple of great researchers, Dr. Ozgur Yildirim and Dr. Zihong Guo, and how they use simulations in their inventing process. They work in an invention/prototype laboratory in Bellevue, WA for Intellectual Ventures, a global leader in the business of invention.
A Cool Way to Consider the Environment
According to a study done by Brunel University in the United Kingdom, the food sector is among the top five energy-consuming industries. The transportation of food, including keeping it refrigerated, is one of the larger contributing factors to this energy-consumption and subsequent greenhouse gas emissions.
IEEE Spectrum’s Insert Cover Story Optimizes Electronics Cooling
The June issue of IEEE Spectrum included an insert focused on Multiphysics Simulation. This included a feature on cooling in hybrid cars, articles about metamaterials, the smart power grid, as well as biomedical applications.
Giving the Power of COMSOL to the Operator
COMSOL News is now available in print and electronically, and you can request your copy of the multiphysics simulation magazine here. One of the great stories concerns a process engineer at Ruukki Metals in Finland, Mika Judin, who not only uses COMSOL to model and optimize his process, but lets the operators use the simulation too.
Heat Transfer: Accounting for the Radiation of the Sun
Knowing the sun’s radiation and thermal effects is very important to designers within the building industry, especially in designing “green” buildings. Heat transfer also plays a vital role in designing outdoor devices in terms of maintaining temperatures in extreme hot or cold environments. To use the words of Nicolas Huc, project leader for the Heat Transfer Module development at COMSOL in France: “it makes a huge difference if you forget to take the sun’s radiation into account.”
Lots of Things to Model in a Wind Turbine
Following up on my previous blog post about protecting wind turbines from lightning strikes, I got to thinking about other modeling aspects of wind turbines. Structural mechanics is of course important, and we have a couple of models that center on this.
Stick a TV to the Wall Using Gecko Feet
Gecko lizards use dry adhesion forces to climb vertical and even backward-slanting walls. Yet, despite the strength they provide for holding their body to such walls, you can easily pluck them from their surface, and no residue is left behind. Imagine doing that with a TV.
