Sir Horace Lamb was a British applied mathematician and professor who wrote several textbooks that became fundamental in physics. Among them is a comprehensive text that was considered the standard for hydrodynamics for many years. His work in this subject resulted in the Lamb vector, the Lamb-Oseen vortex, and Lamb surfaces. He also authored works on sound, statistics, and mechanics.

Plastic floating at sea often winds up in debris-filled gyres, commonly known as garbage patches. These patches of plastic circulating in the ocean pose a danger to wildlife and are slowly entering the food chain. One project aims to remove this debris with floating boom technology, which is often used to contain oil spills.

Did you know that the COMSOL Multiphysics® software allows you to have different discontinuous meshes in neighboring domains? Although the usual default behavior of the software is to use aligned meshes, there are times when we might like to have discontinuous meshes, such as for modeling conjugate heat transfer. Let’s delve deeper into this topic and see how these meshes can save us time and memory in our initial model development with just a little bit more effort.

“Equipped with his five senses, man explores the universe around him and calls the adventure ‘science.’” — Edwin Hubble Imagine if the entire universe consisted of the Milky Way galaxy alone. Most scientists thought this was the case before astronomer Edwin Hubble discovered other galaxies. Considered the founder of extragalactic astronomy, Hubble was one of the leading 20th-century figures in observational cosmology and provided evidence that the universe expands at a constant rate.

Global modeling of plasmas is a powerful approach to study large chemistry sets. In these models, the reactions are represented by rate coefficients. In particular, the rate coefficients of electron impact collisions depend on the electron energy distribution function (EEDF), which is often non-Mawellian and can be computed from an approximation of the Boltzmann equation (BE). Here, we explain how to create a global model fully coupled with the BE in the two-term approximation using the COMSOL Multiphysics® software.

In the 1615 novel Don Quixote by Miguel de Cervantes, the titular character, who fantasizes about being a medieval knight, mistakes windmills for giants and charges at them, only to get his lance stuck in one of the sails. While modern wind turbine blades don’t have to withstand that kind of pointed force, it’s important to perform stress and modal analyses of blade designs to account for various — and more realistic — structural and environmental loads.

Electroplating is commonly used for surface finishing due to its effectiveness across the automotive, electronics, corrosion protection, aerospace, and defense industries. Since WWII, the number of patents claiming to achieve “perfect plating” has increased exponentially. The focus of the narrative surrounding electrochemical plating has also shifted from complex chemical reactions toward perfecting operating conditions. In this blog post, we show how to achieve smoother metal surfaces during reverse pulse plating (RPP) using the COMSOL Multiphysics® software and add-on Electrodeposition Module.

Ever wonder why the sky is blue? Lord Rayleigh answered this question, explaining that the color comes from the scattering of sunlight off small particles in the atmosphere. A prolific scientist, Rayleigh made notable contributions to a wide range of fields, including optics, acoustics, and fluid flow. He is best known for discovering argon, an accomplishment for which he won the Nobel Prize in Physics.
