Electroplating Simulations Cut Down on Wasted Metal
Electrodeposition is the process of making a substance adhere to an object through electrochemical reactions. Sometimes the substance is available in the solution form and other times it is a solid object too, and needs to undergo electrochemical reactions in order to dissolve into solution; often as part of the electrodeposition process. Electrodeposition can be an important part of the refining process of certain metals, such as copper, silver, and gold and is often referred to as electrorefining or electrowinning. […]
Injectable Microbubbles in Hydrology and Healthcare
Microbubbles filled with oxygen can be injected into contaminated lakes to restore the water quality. Typically, water is purified via water-treatment plants, but this microbubble technique is both inexpensive and more environmentally-friendly in comparison. As seen in a COMSOL News 2011 article, oxygen microbubbles are a researcher’s way of copying nature’s own self-restoration mechanism for cleaning contaminated lakes.
Joule Heating Simulations Tutorial
One of the classic multiphysics couplings in engineering and science is Joule heating, also called resistive heating or ohmic heating. Some Joule heating examples include heating of conductors in electronics, fuses, electric heaters, and power lines. When a structure is heated by electric currents, the device can reach high temperatures and either structurally degenerate or even melt. The design challenge is to remove this heat as effectively as possible. COMSOL eases these challenges by providing a specialized multiphysics interface for […]
Modeling Lithium-Ion Battery Cooling
Get a brief introduction to creating a lithium-ion battery model using the COMSOL Multiphysics® software in three sequential studies. At the end of the blog post, there is a link to download the tutorial model.
Industry: Continuum Blue Simulates Structural Mechanics
On January 10th, hundreds of people tuned in to hear COMSOL and Continuum Blue discuss Structural Mechanics simulations in certain industry applications. As promised in my previous blog post on multiphysics modeling webinars happening in 2013, here is a round-up of the event — including a video excerpt detailing three structural analysis examples presented by Continuum Blue.
Video: Modeling Mechanical Applications
How do you avoid product failure down the line? By ensuring you manufacture accurate parts and assemble them correctly, of course. Manufacturing success stems from good design ideas. “Good ideas” are not conjured up at random; good ideas are those that are based on real-world physical principles. This video will show you how your company can infuse sound concepts into the early product development stages by modeling mechanical applications in COMSOL Multiphysics.
Gold Nanorods for Medical Treatment
Nanorods are synthetic nanoscale objects used in the area of nanotechnology. They can be synthesized from semiconducting materials or metals, such as gold. The applications of nanorods are many, ranging from display technologies and energy harvesting to cancer therapy.
Magnetic Shells Designed to Improve Energy Transfer
Engineers and scientists are known to step up to the challenges posed by nature. After developing an understanding of how the current object or process works, the next step often includes figuring out how to manipulate the situation to improve said object or process. One such example is cloaking; controlling light and sound waves to render something invisible. Phys.org recently ran a story on progressive research on controlling magnetic fields via cloaking to harvest and transfer energy using a magnetic […]
