Solar Radiation: How Engineers Can Stay Cool on the Beach (Maybe)

Fanny Littmarck August 29, 2012

The end of August marks the end of summer here in New England. Already nostalgic and unwilling to let the season go, I decided to look into some “beach physics”. In May we released a new solar radiation feature in our Heat Transfer Module that will be helpful in many solar applications — including how to avoid overheating on the beach, apparently. Here’s how engineers can stay cool on the beach.

When it gets dark, you flick on the lights. If you were to model this simple example, you would need to take all forms of heat transfer within consideration; convection, conduction, and radiation are all at play when a light bulb is flicked on.

One of our Certified Consultants, Dr. Roger Pryor, wrote a book about “Multiphysics Modeling using COMSOL 4” in February this year. The book covers multiphysics problems ranging from relatively easy to relatively difficult, from 1D to 3D. Now, Dr. Pryor’s book on COMSOL version 4 is used in his brand new COMSOL training series in Troy, MI.

Additive manufacturing, or 3D printing as it is more widely known as, is on everybody’s mind right now. Manufacturing folks, engineers, and even the general public have taken an interest in 3D printing. In other words, this is not just a fascinating phenomenon to those in the industry — additive manufacturing has been generally accepted as the next “cool” thing in manufacturing.

The most common type of aortic aneurysms is that which occurs in the abdominal region. When a person experiences an abdominal aortic aneurysm (AAA), his or her abdominal aorta is dilated to the extent that its diameter is increased by over 50%. With symptoms lacking a sense of urgency (we’ve all ignored stomach pains before), if left untreated an AAA may rupture — whereon the victim’s life is on the line. An Intra-Luminal Thrombus is typically involved in AAAs, but […]

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.

We’ve been running these “Lunch Time Web Tutorials” over the past couple of months, featuring 45 minutes of solving a particular problem following a comprehensive step-by-step format. Each webisode involves a different type of engineering problem, one of which focused on the modeling of a gate valve in a pipe branch. We are now making this available as a set of two videos for those who missed the live tutorial.

It’s no news that multiphysics simulations can help companies build better products, and every day COMSOL users bring new product designs or ideas for improvements to life. That said, every so often someone does something particularly fascinating. If you’re following along the email communications from AltaSim Technologies you will receive a technology breakthrough message this week. This latest email from AltaSim is bringing attention to an important clean energy project they are working on with Dais Analytic for the U.S. […]

After reading about the COMSOL users over at MACCOR in David’s blog post I decided to watch Venus’ transit of the sun live via their online stream from Tulsa, OK. This was a once in a lifetime opportunity that I, like many people around the world, did not want to miss.

There are many exciting new features in the Particle Tracing Module for COMSOL Multiphysics version 4.3. The secondary particle emission feature is particularly fascinating. “This new option for the Wall Condition allows you to model filter multipliers and multipactors, which were previously very difficult to model”, says Dan Smith, Development Team Leader at COMSOL. A mathematical expression, like a logical expression containing the particle energy for instance, can be used to determine the number of secondary particles to be released. […]

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.”
