Happy Birthday, Sir William Henry Perkin

Brianne Christopher March 12, 2019

What did you want to do with your life at the age of 18? Sir William Henry Perkin was trying to produce a treatment for malaria by synthesizing quinine. Instead, his experiments led him to produce the first synthetic dye of the color we now know as mauve. Let’s learn more about the British chemist responsible for adding more color to our world…

Price is a common lament among coffee drinkers, with upscale roasters and chains charging upwards of five dollars for a single caffeine fix. Brewing your own coffee can cut down on the expense, but if you invest in high-quality coffee beans, you’ll want to ensure that their flavor and aroma last. A popular “life hack” is to put them in the freezer, but is this effective? To answer this question, let’s turn to science…

The EPFLoop team took the stage at the COMSOL Conference 2018 Lausanne with their hyperloop pod design, setting it down for the crowd to see. Learn about the different ways that the team of students and faculty from the École Polytechnique Fédérale de Lausanne, led by Mario Paolone and including Nicòlo Riva, Zsófia Sajó, and Dr. Lorenzo Benedetti, used multiphysics simulation to land in the top spot for hyperloop design at the 2018 SpaceX competition.

In a fluid-structure interaction (FSI) scenario, the fluid can affect the structure, the structure can affect the fluid flow, or both. When modeling a device that relies on FSI, you may want to simulate one of these options, a combination, or all three. The Fluid-Structure Interaction multiphysics coupling in the COMSOL® software makes it easy to implement FSI in your analyses. In this blog post, we study the flow through a ball check valve for different flow directions and pressures.

The COMSOL Conference 2018 Lausanne provided attendees with an exciting taste of all that Switzerland has to offer, including a musical performance by alpine horn players, a traditional Swiss wine and cheese reception, and a trip to the European Organization for Nuclear Research (CERN) in Geneva. Just as diverse were the research presentations given by conference attendees, who traveled from around Europe, and as far as South Africa, to discuss their innovative work with our multiphysics simulation community.

Is the boundary element method (BEM) a viable alternative to FEM for magnetostatics modeling? In a three-part series of tutorials, we perform electromagnetic force calculations using the Maxwell stress tensor to demonstrate the capabilities of BEM. The results are validated against analytical models and compared with results from FEM to show the value and utility of boundary elements for this purpose. Read on for a preview of what you’ll learn in the tutorial series.

In 1880, Alexander Graham Bell wrote a letter to his father, saying: “I have heard articulate speech by sunlight! I have heard a ray of the sun laugh and cough and sing!” He was talking about his latest success, the photophone, which he called his “greatest invention” shortly before his death. The photophone did not revolutionize the field of imaging, but an unintended effect Bell noticed while developing it did…

If you ever visit the extravagant dome within St. Paul’s Cathedral in London, be careful what you say. As Lord Rayleigh discovered circa 1878, the vaulted structure exhibits an interesting acoustics phenomenon: Whispers from one part of the dome can be clearly heard in other areas. Rayleigh called the effect a “whispering gallery”. Surprisingly, you can observe a similar effect in another field of science entirely: light waves traveling in an optical ring resonator.
