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 […]
Researching Carbon Fiber Reinforced Plastic Acoustic Guitars
There are traditional acoustic guitars made of wood, and now there are also those made entirely out of carbon fiber reinforced plastic (CFRP). Do these plastic guitars sound like their wooden forbearers? Guess what, you can use computer modeling to find out.
Wind Turbines in Urban Settings a Reasonable Idea
If I asked you to envision a wind turbine, odds are you’d picture a wind farm in some remote location. With good reason; that’s commonly where they are found. If you’re a student or faculty of Case Western Reserve University, on the other hand, you might think of the wind turbine you have on campus. Does it make sense to set up wind turbines in urban settings? These two researchers suggest that it does.
Efficient Heat Exchanger, it’s all in the Pipes
Nature is full of counter-intuitive phenomena; I’m fascinated by everyday examples like the one we talked about this summer, sinking bubbles in a pint of Guinness, but I have to say that engineering has its fair share of such examples too. The concept of heat exchange in coaxial pipes struck me as a student, as it showed me the relentless tinkering attitude typical of engineers wanting to optimize their design. In this kind of heat exchanger both streams, hot and […]
Power Transistors and Heat Transfer
Transistors are building blocks of electronic appliances, and can be found in radios, computers, and calculators, to name a few. When working with electrical systems you typically have to deal with heat transfer; electric heating is often an unwanted result of current conduction. Is a heat sink mounting necessary to keep the transistor cool, or can it manage without? Let’s have a look at power transistors from a heat transfer perspective.
Is Fracking Safe? Scientists Turn to Simulation to Investigate
Hydraulic fracturing (popularly referred to as “fracking”) is a method to increase production of oil and gas from certain types of geological formations. It has been used for decades, but recently, as the practice has increased, fracking has become a controversial topic. I will avoid taking sides in this debate, but the fact that there is a conflict implies there needs to be a deeper understanding of the process and its effects.
