Simulating Heating of Brake Discs in a Car

February 27, 2013

Cars need brakes for obvious reasons, and you don’t want these to fail. Brake failure can be caused by many things, one of which is the overheating of the brake’s disc. As I’ve said before, no engineer wants to design a product that fails, which is also true in the case of brake-disc design. Let’s study a scenario of a car in panic brake mode, and find out how hot the brake discs and pads get as well as how […]

Long-time Multiphysics User on COMSOL for Heat Transfer

February 21, 2013

Having used COMSOL Multiphysics for over six years now, we are pleased to have Dr. Jon Ebert, Director at SC Solutions, join us in the next Mechanical Engineering Magazine Webinar Series titled “Heat Transfer in Solid and Fluids”. On March 7th, he will co-host an instructional webinar together with COMSOL’s John Dunec. Dr. Ebert will discuss SC Solution’s simulation activities within a wide span of heat transfer-related applications, particularly with respect to semiconductor manufacturing. As a long-time user of COMSOL […]

Upgrading the Nuts and Bolts of the Electrical Grid

February 20, 2013

The electrical grid describes the network created for producing electricity, transmitting it and delivering it to the consumers. A “smart grid” is an electrical grid that gathers information on the suppliers and consumers automatically to improve efficiency and sustainability in the system. As the automated technology improves, the hardware that physically connects the electrical grid together must improve as well. This hardware, the “nuts and bolts” of the grid, is comprised of transformers, cable joints, terminations, bushings, and fault current […]

Modeling Lithium-Ion Battery Cooling

January 21, 2013

Get a brief introduction to creating a lithium-ion battery model using the COMSOL Multiphysics® software in three sequential studies. At the end of the blog post, there is a link to download the tutorial model.

The Science of Cooking, Multiphysics meets Food

January 17, 2013

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 […]

Gold Nanorods for Medical Treatment

January 10, 2013

Nanorods are synthetic nanoscale objects used in the area of nanotechnology. They can be synthesized from semiconducting materials or metals, such as gold. The applications of nanorods are many, ranging from display technologies and energy harvesting to cancer therapy.

Power Transistors and Heat Transfer

January 2, 2013

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.

Modeling a Burning Candle, How Would You Do It?

December 25, 2012

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.
