Another Danger with Corrosion

Phil Kinnane June 12, 2012

It’s long been known that a danger with corrosion is that it compromises the structures that it affects. This is particularly relevant for the naval industry where material failure leads to leaks and the like. Now, another danger is becoming apparent.

Before you drink your next pint of Guinness, have a close look at the bubbles in the brew, and see if they sink. Apparently they do. Now a group of scientists from the University of Limerick in Ireland (where else?) has modeled the phenomenon of sinking bubbles in Guinness beer to lend weight to this finding and provide a theoretical explanation.

After reading about the COMSOL users over at MACCOR in David’s blog post I decided to watch Venus’ transit of the sun live via their online stream from Tulsa, OK. This was a once in a lifetime opportunity that I, like many people around the world, did not want to miss.

One of the interesting stories from this year’s COMSOL News is the article concerning Johnson Screens®. They manufacture steel screens to block debris in water for pipes and valves. Their challenge is to design water intake screens with openings large enough for an unimpeded flow of water, but small enough to block enough debris depending on a specific application. This means that each screen must be custom-designed taking into account the characteristics of the debris and the depth at which […]

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. […]

You may already be familiar with large regenerative heat exchanger (RHX) systems, but what about much smaller micro-channel systems? That’s just the type of invention the research teams at Intellectual Ventures (IV) are working on.

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.

On the 17th of May, 27 engineers and scientists related to the oil and gas industry gathered in Northwest Houston to learn more about COMSOL Multiphysics applications for well logging. This area of research and development is of particular interest to the oil services companies, who make tools that help maximize the output from wells. These tools are highly advanced technological devices. They work by being inserted into a wellbore and detecting how much hydrocarbon (e.g., oil) is in the […]

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.”

I was just reading one of my favorite sites, phys.org, about the difficulties of working with nanostructures. In the world of batteries, you want to maximize charge, while minimizing volume and weight. This means that the nano-world is starting to take hold, but, as has been discovered with many other applications where nanotechnology is being applied, it is very difficult to control the material properties in this world.
