A Closer Look at the Physics Involved in Lava Lamps
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.
A Cooling Story for These Sweltering Days
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
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.
Inventing Makes use of Simulation
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.
A Cool Way to Consider the Environment
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.
Giving the Power of COMSOL to the Operator
COMSOL News is now available in print and electronically, and you can request your copy of the multiphysics simulation magazine here. One of the great stories concerns a process engineer at Ruukki Metals in Finland, Mika Judin, who not only uses COMSOL to model and optimize his process, but lets the operators use the simulation too.
Heat Transfer: Accounting for the Radiation of the Sun
Knowing the sun’s radiation and thermal effects is very important to designers within the building industry, especially in designing “green” buildings. Heat transfer also plays a vital role in designing outdoor devices in terms of maintaining temperatures in extreme hot or cold environments. To use the words of Nicolas Huc, project leader for the Heat Transfer Module development at COMSOL in France: “it makes a huge difference if you forget to take the sun’s radiation into account.”
Therapeutic Heat, Electromagnetic and Electrochemical Treatment
A couple of days ago I blogged about the team at Lahey Clinic who are using COMSOL Multiphysics to model their neuromodulation therapy of patients. In their example, they place electrodes close to the spine and, through electric current, stimulate the area around these electrodes to relieve back pain. The reason why modeling is important for them is because it’s quite difficult to actually access these treatments to measure their effectiveness and possible detriments.
