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.
News in Particle Tracing for 4.3
There are many exciting new features in the Particle Tracing Module for COMSOL Multiphysics version 4.3. The secondary particle emission feature is particularly fascinating. “This new option for the Wall Condition allows you to model filter multipliers and multipactors, which were previously very difficult to model”, says Dan Smith, Development Team Leader at COMSOL. A mathematical expression, like a logical expression containing the particle energy for instance, can be used to determine the number of secondary particles to be released. […]
Are you Ready for the June 5th Venus Transit of the Sun?
“At 5:00 central time, June 5th 2012, Venus will transit the sun. It will not do so again until December 2117. The task at hand is to provide a live webcast of the transit as seen from Tulsa, OK.”
Design Materials to Exhibit Wanted Properties
I’ve just been reading my favorite news service, www.physorg.com, and noticed that cloaking is once again the topic of the day. While we have previously reported on a group out of Duke University, this article mentions a group from Ames Laboratory in Iowa. Similar to the Duke Group, Costas Soukoulis from Ames Laboratory also seems to have been at the forefront of this research.
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.
