Coal: The Energy of Right Now

November 26, 2012

While alternative energy is the energy of the future, fossil fuels are the energy of right now. Coal, especially, is still heavily relied on for energy production and is a primary source of electricity generation in many countries including the US and China. In fact, world coal consumption is actually increasing year-to-year. Scientists need to be concentrating on how to make alternative energies more widespread, but they also need to make coal a better, more efficient fuel source. Designing systems […]

The First Flyer Optimized Using Multiphysics

November 12, 2012

December of 1903 marked the commencement of the Age of Powered Flight, and the Wright brothers went down in history. This was a time before personal computers and simulation software existed. Determining the optimal design of their airplane had to be done using physical prototypes and real-life experiments. What had the design looked like if the Wright brothers had been able to use computers and modeling software? Three researchers from Pennsylvania State University sought to find out how the design […]

Vacuum System Simulations Webinar and Videos

November 1, 2012

Since I joined COMSOL in 2010 I’ve presented about half a dozen webinars. Last week we held a webinar on Vacuum System Simulations and it was definitely the most fun webinar to-date. Historically, simulation has not been used extensively in the vacuum industry, so I was nervous that there wouldn’t be much interest in such a specialized topic.

Piezoelectric Energy Harvester Helps Increase a Car’s Efficiency

July 26, 2012

Much has been written lately about increasing the energy efficiency of cars. Batteries and fuel cells are very hot topics, and not so long ago I blogged about the University of Michigan’s use of solar cells to fully power a car. Yet, even on the smallest of scales, such as the sensors in your car, improvements are being made. Utilizing a MEMS (Micro Electromechanical System) piezoelectric energy harvester, Alexander Frej and Ingo Kuehne at Siemens Corporate Technology in Munich are […]

A Closer Look at the Physics Involved in Lava Lamps

July 19, 2012

Remember those retro desk ornaments of the 1960’s, those lamps filled with colorful wax that began to move when the lamp was lit? I’m talking about lava lamps, or as I like to call them, “Rayleigh–Taylor instability machines”. They may not be popular among today’s youth, but I still own one and I thought it would be interesting to look beyond the dyed blobs of wax and observe the physics involved in lava lamps.

The Secret Sauce in the Pipe Flow Module

June 22, 2012

We developed COMSOL Multiphysics to empower the engineering and science communities with state-of-the-art simulation tools. A key ingredient of this empowerment is flexibility. COMSOL users are already well aware of the full compatibility between various physics. This means you can put any (yes, really any) combination of COMSOL physics together. But that’s not the only way our multiphysics simulation tool is flexible.

A Cool Way to Consider the Environment

June 20, 2012

According to a study done by Brunel University in the United Kingdom, the food sector is among the top five energy-consuming industries. The transportation of food, including keeping it refrigerated, is one of the larger contributing factors to this energy-consumption and subsequent greenhouse gas emissions.
