How to Model Electrodynamic Magnetic Levitation Devices

November 28, 2016

Electrodynamic magnetic levitation can occur when there are time-varying magnetic fields in the vicinity of a conductive material. In this blog post, we will demonstrate how to model this principle with two examples: a TEAM benchmark problem of an electrodynamic levitation device and an electrodynamic wheel.

Designing a Power Generation Source for Bicycle Safety Lights

November 22, 2016

Today, we invite guest blogger Rune Thygesen of Reelight to discuss designing a power generation source for bicycle safety lights using simulation. At Reelight, we are developing an affordable bicycle safety light that is extremely easy for the end user to install. Along with a stronger and more flexible mounting system, we needed to develop a new power generation platform. Using simulation-based design, we created a power platform that is easy to use and quick to install.

Students Use Simulation to Optimize Hyperloop for Design Competition

November 8, 2016

Today, we invite guest blogger Bauke Kooger of Delft University of Technology to discuss modeling a magnetic suspension system for the Hyperloop. The Hyperloop is a proposed mode of transportation in which a vehicle, or pod, travels at the speed of sound through a low-pressure tube. At this speed, a magnetic suspension offers several advantages over systems such as air bearings or wheels. To test this, Delft’s Hyperloop team modeled their pod’s magnetic suspension in the COMSOL Multiphysics® software.

How to Automate Winding Design in Electrical Machines with an App

October 26, 2016

Aside from the winding type, concentrated or distributed, the logic behind the design of electrical machines is relatively similar, as it’s based on their phasor diagrams. Using an induction motor benchmark model with a concentrated winding, we’ll show you how to create selections in the COMSOL Multiphysics® software to streamline the analysis of your winding design. We’ll then demonstrate how to further advance your simulation studies by automating these processes with the Application Builder.

ABB Minimizes Transformer Hum with Simulation

August 9, 2016

We rely on power transformers for everyday tasks, but these devices also create a loud buzzing or humming noise. This sound comes from vibrations in different parts of the transformer and is impossible to eliminate completely. To reduce the noise, a team of engineers at ABB Corporate Research Center simulated the acoustic, electromagnetic, and mechanical behavior in their transformer systems with the COMSOL Multiphysics® software.

Using Apps to Optimize Induction Heating for Food Processing

August 1, 2016

Modern food processing techniques are constantly being analyzed and improved. To evaluate the efficiency of such techniques and the equipment that they utilize, researchers and engineers can turn to simulation tools like COMSOL Multiphysics. Numerical modeling apps are helping to bring this simulation power to a wider audience, accelerating the optimization of such processes along the way. Let’s see how this applies to the analysis of induction heating for food processing.

Particle Tracing in a Component of a Quadrupole Mass Spectrometer

July 25, 2016

Quadrupole mass filters, the key component of quadrupole mass spectrometers, filter ions by their charge-to-mass ratio, only allowing ions with a certain ratio to pass through the device. As such, a high transmission probability for a specific ion through the filter is desirable. However, fringe fields in the mass filter can affect this probability. By using multiphysics simulation, we can take a closer look at quadrupole mass filters and investigate the effect of fringe fields on these devices.

Do Bumblebees Use Their Hairs or Antennae for Electroreception?

July 19, 2016

While bumblebees are not a complete mystery, we still have a lot more to learn about these helpful insects. A topic with a lot of buzz surrounding it is how they find food. Using electroreception, an ability most often found in aquatic animals, is one possibility. But how do bumblebees use electroreception? To find answers, a research team at the University of Bristol combined the power of physical experiments and simulation.
