A mixer that doesn’t move may sound like an oxymoron, but it’s not. Used in various chemical species transport applications, static mixers are inexpensive, accurate, and versatile. Still, there is always room for improvement. Optimizing the design of static mixers calls for computer modeling, but traditional CFD methods may not be the best way to model these mixers. How do these motionless mixers work and how can their performance be simulated?

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. […]

It’s been fun working with the next release. One of the great new features will be in the Particle Tracing Module and will allow particles to interact with each other, and not only with the macroscopic field they find themselves in. It also produces some pretty cool vids.

The Particle Tracing Module webinar was a huge success. Over 1,250 people signed up for it and saw our lead developer, Dan Smith, demonstrate the product and explain the science behind it. He received a lot of questions during the webinar, and our support engineers are currently helping him answer them.

The release of Version 4.2a was an exciting event for us at COMSOL. I had the opportunity to see a preview of new products and the big one for me was the Particle Tracing Module. Many of our customers and colleagues in the simulation industry had been requesting this for quite some time. I must admit that I thought it was just because they wanted a different type of postprocessing feature; another way of looking at streamlines.
