Multiscale Reactors: Cleaning the Flows

Niklas Rom | November 3, 2014

Probably the most common reactor in the chemical industry is the packed bed reactor. This reactor is used in chemical synthesis and for effluent treatment and catalytic combustion. Oftentimes, heterogeneous catalysis requires packed beds. A common design is a cylindrical column filled with catalyst pellets. The pellets can be contained within supporting structures, like tubes or channels, or packed in a single compartment in the column. The latter is called dumped packing.

It’s here. We have now released the latest version of COMSOL Multiphysics® simulation software — version 5.0 — and it’s revolutionary. Why? You will now be able to turn your COMSOL Multiphysics models into apps and share them with your colleagues and customers. We are also releasing three new add-on products and numerous updates to existing products. Here’s a quick run-down of the release news.

Last month, my colleague Ruud described some of the most effective ways to use arrow plots in your COMSOL Multiphysics simulation results. In this next installment of the postprocessing series, I’ll continue with slice plots, which are an easy way to visualize physics behavior on many different parts of your model.

The 10th annual COMSOL Conference Boston recently wrapped — and it was a huge success. The event brought together 300 engineers, researchers, and scientists from around the globe to hear the latest advancements in multiphysics simulation, including the much anticipated upcoming release of COMSOL Multiphysics 5.0.

In a previous blog post, we focused on the growing use of magnetic cooling technology as a safer, more eco-friendly method of refrigeration. Here, we look at how one team of researchers analyzed the potential use of this technology in the design of electric vehicles.

Figure skating is a beautiful but dangerous sport; repetitive jumping and landing on ice can cause a lot of joint stress. Researchers are working on “smart” blades to measure the force that is exerted on the ice. The data could then be used to prevent injuries.

Nanoparticles may be microscopic in size, but their potential in shaping imaging techniques for biomedical research is vast. Let’s explore the properties of nanodiamonds and investigate new research that is advancing their role in observing and analyzing cell processes.

One of the most common questions we get is: How large of a model can you solve in COMSOL Multiphysics? It turns out that this is quite tricky to answer decisively, so in this blog entry, we will talk about memory requirements, model size, and how you can predict the amount of memory you will need for solving large 3D finite element problems.

When modeling plasmas, various options exist for choosing an ion temperature. Your choice, however, may strongly influence your model’s results. Let’s discuss the theoretical reason behind this phenomenon and study an example involving an inductively coupled plasma (ICP) to illustrate the influence the different ion temperature options have on your model’s results.

While the earth’s magnetic field typically remains stable, studies have shown that irregular intervals known as geomagnetic reversals have occurred throughout history. Here, we investigate the background behind these flips and how a new study has provided surprising details into the most recent reversal.
