Joule Heating Simulations Tutorial
Fanny Griesmer January 29, 2013
One of the classic multiphysics couplings in engineering and science is Joule heating, also called resistive heating or ohmic heating. Some Joule heating examples include heating of conductors in electronics, fuses, electric heaters, and power lines. When a structure is heated by electric currents, the device can reach high temperatures and either structurally degenerate or even melt. The design challenge is to remove this heat as effectively as possible. COMSOL eases these challenges by providing a specialized multiphysics interface for […]

It’s that time of year again for all the foodies out there; on January 29th the 2013 Bocuse d’Or will be in full swing with 24 chefs each representing their country, vying for the Gold Medal in the Olympic Games of the culinary world. In this biennial event, the chefs will have to combine classical and innovative cooking techniques to come out on top. At the last Bocuse d’Or in 2011, Gunnar Hvarnes propelled past the competition with the aid […]

Transistors are building blocks of electronic appliances, and can be found in radios, computers, and calculators, to name a few. When working with electrical systems you typically have to deal with heat transfer; electric heating is often an unwanted result of current conduction. Is a heat sink mounting necessary to keep the transistor cool, or can it manage without? Let’s have a look at power transistors from a heat transfer perspective.

This holiday season most of us will have burned our fair share of candles. The flickering light of candles can really enhance the ambiance and put you in festive spirits. This reminds me of an analysis of a burning candle developed by AltaSim Technologies back in 2010. So, in tune with the holiday cheer, here are some candle physics.

The winter here in Boston has been very mild so far. A few days I would even have liked to have the air conditioning back on. I checked in with one my colleagues to check if he was having an equally hard time staying cool, and to my surprise, he was not. Why? He had constructed a make-shift air conditioner (A/C).

One of the differences between this year’s COMSOL Conference, and previous years’, is that this year we filmed a lot of it. During the next few weeks we will be publishing some of these videos for those that were there, to enjoy it once again, and for those that weren’t to get a taste of what went on. To kick these all off, I’m proud to present the first keynote video, which takes us to Babel.

Out of all metals, the most frequently extruded is aluminum. Aluminum extrusion entails using a hydraulic ram to squeeze an aluminum bar through a die. This process will form the metal into a particular shape. Extruded aluminum is used in many manufacturing applications, such as building components for example. The process of shaping metal alloys, like aluminum, can be modeled using COMSOL Multiphysics.

The end of August marks the end of summer here in New England. Already nostalgic and unwilling to let the season go, I decided to look into some “beach physics”. In May we released a new solar radiation feature in our Heat Transfer Module that will be helpful in many solar applications — including how to avoid overheating on the beach, apparently. Here’s how engineers can stay cool on the beach.
