Nature is full of counter-intuitive phenomena; I’m fascinated by everyday examples like the one we talked about this summer, sinking bubbles in a pint of Guinness, but I have to say that engineering has its fair share of such examples too. The concept of heat exchange in coaxial pipes struck me as a student, as it showed me the relentless tinkering attitude typical of engineers wanting to optimize their design. In this kind of heat exchanger both streams, hot and […]

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.

We have been adding a lot of content to our website lately, involving the new LiveLink™ for Excel®. It’s a welcomed addition to the COMSOL family and we can’t stop talking about it. We want to make sure everyone knows about the strengths of LiveLink™ for Excel®, and how it can make your modeling easier, more efficient, and more powerful. Now we have another video for you, and this one demonstrates how to add data from Excel® to a COMSOL […]

Hydraulic fracturing (popularly referred to as “fracking”) is a method to increase production of oil and gas from certain types of geological formations. It has been used for decades, but recently, as the practice has increased, fracking has become a controversial topic. I will avoid taking sides in this debate, but the fact that there is a conflict implies there needs to be a deeper understanding of the process and its effects.

The Pratt truss is one of several different types of truss bridge designs out there. Said to be the oldest type of modern bridge, the truss is simple and lends itself well to analysis. This type of bridge is typically constructed for the use of pedestrians, cars, trucks, trains, and pipelines.

Hybrid vehicles are no longer a new concept, but that does not mean research and development (R&D) has ceased. If anything, it is ramping up as demand for hybrid design optimization continues to grow. Ercan Dede from Toyota Research Institute of North America held a keynote talk at the COMSOL Conference Boston 2012 on how they are using multiphysics modeling for advanced vehicle systems R&D. If you weren’t there, you can now watch his keynote in a video format instead.

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).

Each year we are excited to gather thousands of customers at the worldwide COMSOL Conference series. The events enable the entire user community to see the great projects colleagues have been working on and catch up face-to-face. This year, we wanted to capture some of these conversations and share them with you. That is why we sent our video director, Matt Milhomme, to the COMSOL Conference 2012 in Boston to conduct some interviews. We now have a video series of […]
