Modeling Convective Cooling of Electrical Devices
One of the main issues with high-power electrical devices is thermal management. Together with BLOCK Transformatoren-Elektronik GmbH, we created a model using COMSOL Multiphysics simulation software that encompasses all of the important details when modeling heating of high-power electrical devices. To do so, we had to utilize high performance computing (HPC) with hybrid modeling. Here, we will discuss how to approach this real-life task with the COMSOL software.
Computing Voltages Produced by Electromagnetic Induction
When you lose power at home, you may use a shaker flashlight to navigate about your house. This type of flashlight relies on voltage produced by electromagnetic induction in order to be powered. How much voltage can one of these flashlights produce, do you think? Here, we find out through computation, using the AC/DC Module.
POWER Prevents Corona Discharge in Power Lines
Modernizing the power grid is a huge undertaking. The power industry is mustering up its vast engineering knowledge base to develop the components and systems that will bring us efficient and reliable electrical power for decades to come. By leveraging highly accurate simulation technology with knowledge gained over decades of analyzing in-service equipment, engineers are creating new designs as well as retrofitting proven technology.
Simulating the Focusing Effect of Magnetic Quadrupoles
If you walked into a particle or nuclear physics center, like the world-renowned CERN, you may come across a magnetic quadrupole lens (after security clearance, I would imagine). Here, we’re going to discuss what magnetic quadrupole lenses are and study the focusing effect three consecutive quadrupole assemblies have on B5+ ions traveling through such a lens.
Powerful Packaging for Electronics in Extreme Environments
The power electronics industry is responsible for products used by billions of people: smartphones, televisions, certain car parts, and even components in motors and household objects. With such a diverse array of applications, many design requirements are considered during the making of these products, including power and energy density, cost, and customer safety. Arkansas Power Electronics International (APEI), a USA-based company, is refining designs for power packaging to control thermal management in power electronics devices, increase efficiency, and lower cost.
Solving TEAM Problem 7 with the AC/DC Module
Have you been looking for software that can solve the Testing Electromagnetic Analysis Methods (TEAM) Problem 7? We solved the problem with COMSOL Multiphysics and the AC/DC Module. Here are the results.
The Electromechanical Response of a Brake Design
We have the pleasure of introducing guest blogger, Mark Yeoman of Continuum Blue, who showcases what they can do for clients in the electromechanical brake field. Electromechanical brakes come in various designs, including single to multiple friction-face systems, power-off and power-on types, and those that include permanent magnets. With so many options, how do engineers make the right design choices for their application? With COMSOL Multiphysics, this can easily be done. Here, I will show you how.
Modeling Superconductivity in a YBCO Wire
Superconductors are used in applications where high current density and magnetic fields are present — including electric generators, biomagnetic technology, and common products, such as fast digital circuits. Theoretically, an unlimited amount of current can flow through a wire made of a superconducting material. However, what happens to a superconductor as the current density exceeds critical limits? Let’s find out.
