Singing Sand Leads to Many Questions

July 11, 2012

I know, I know… I should spend the weekend relaxing. But every place I visit offers me a variety of natural phenomena I wasn’t aware of and, as an engineer and a multiphysics enthusiast, I can’t help but sit in the sun jotting down a list of the physics involved – possible coupling mechanisms, boundary conditions, materials, and so on (we talked about stereotypes attached to engineer on our Facebook page in May).

A Cooling Story for These Sweltering Days

July 6, 2012

I have just come back from a bit of a vacation and boy was it hot! Here, a large part of the US has been going through record high temperatures and most of my time was spent trying to keep cool. How nice then to mention a story about cooling.

Space Fuel: Oak Ridge National Laboratory to Produce Plutonium-238

July 4, 2012

The end of July marks the beginning of a $20 million R&D project led by the Oak Ridge National Laboratory (ORNL) to produce and process plutonium-238. The U.S. space program will be using the Pu-238 that is to be produced by ORNL as fuel for future deep-space missions.

Improving Ultrasound Imaging Systems by Directing Sound Waves

June 29, 2012

In an earlier blog post, I commented on how acoustic waves are being used in a biomedical setting, to identify malaria in small fluid samples. A more traditional use of piezoelectric devices was written about in the latest COMSOL News. Here, an Italian company, Esaote S.p.A., uses them to produce improved ultrasound imaging systems.

Inventing Makes use of Simulation

June 28, 2012

One of the interesting stories to come out of the latest COMSOL News concerned a couple of great researchers, Dr. Ozgur Yildirim and Dr. Zihong Guo, and how they use simulations in their inventing process. They work in an invention/prototype laboratory in Bellevue, WA for Intellectual Ventures, a global leader in the business of invention.

SAWs are also used to Manipulate and Mix

June 26, 2012

I have always connected Surface Acoustic Waves (SAWs) as phenomena useful for sensors; where SAW devices act as the medium that transfers mechanical energy (of what you’re measuring) to electrical (what’s used to measure it). SAWs would occur at the surface of a piezoelectric device, mechanically changing it, and then the resulting electrical behavior would be used to provide the measurement. We have a great example that shows how such things can be modeled in a SAW gas sensor.

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.
