Heat Transfer

Valerio Marra | 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 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.

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 within account”.

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.
