Modeling Hydrodealkylation in a Membrane Reactor
The design of the reactor used in hydrodealkylation can have a significant impact on the overall yield and selectivity of the conversion product. In this blog post, we use modeling and simulation to investigate the advantages of using a membrane reactor.
How Much Memory Is Needed to Solve Large COMSOL Models?
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.
Photos from the COMSOL Conference 2014 Boston
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.
Ion Temperature in Inductively Coupled Plasmas (ICPs)
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.
Designing Electric Vehicles with Magnetic Cooling Technology
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.
The Mystery Behind the Earth’s Magnetic Field Flip
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.
Green Energy Management for Communication Systems
The communication network wasn’t designed to carry the amount of traffic that is currently transmitted around the world on a daily basis. With the rapid expansion in data traffic and the exponential growth in high-speed communications, the current network is coming under increasing strain. At Bell Labs, researchers are looking into ways to improve energy efficiency through the use of optimized electronics cooling and energy harvesting technology. Two new energy-savings approaches developed by the group promise significant savings.
Yield Surfaces and Plastic Flow Rules in Geomechanics
In order to ensure safe geotechnical building methods, specific applications require certain foundations and structure reinforcements. Tests are quite expensive to carry out, so simulation can be really useful and even essential. Many numerical models have been developed to give a deep insight into soil behavior. Here, we introduce the most widespread models for soils available in COMSOL Multiphysics and analyze a tunnel excavation example.
