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.

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.

Polymer electrolyte membrane or proton exchange membrane (PEM) fuel cells provide a potentially clean and portable source of power. This is of major interest to the transport industry as well as for power generation at fixed sites. COMSOL Multiphysics is a powerful simulation tool you can use to help understand and overcome PEM fuel cell design and construction challenges.

Mixers with rotating components are essential in many industrial applications, including food production, manufacturing chemicals, pharmaceuticals, and other consumer products. While the industrial processes of mixers differ, product requirements like quality, reproducibility, and uniformity must remain constant. Using the Mixer Module is one way you can make sure these product requirements are met. In our upcoming webinar, you’ll learn how the fluid flow interfaces available in the Mixer Module allow you to streamline the design of mixers and their mechanisms.
