Keynote Video: Modeling the Multiphysics Behavior of Nuclear Fuel

Bridget Paulus November 6, 2017

Optimizing fuel for nuclear reactors can increase the amount of power they generate, improve their safety, and lower greenhouse gas emissions. However, studying nuclear fuel can be complex, as it involves interactions between multiple physical phenomena. In his keynote talk from the COMSOL Conference 2017 Boston, Andrew Prudil of Canadian Nuclear Laboratories (CNL) discussed using multiphysics models to gain insight into nuclear fuel. If you missed his presentation, find a video recording and summary below.

Extraordinary optical transmission (EOT) is an important process in terahertz applications. Developing EOT applications could lead to improvements in medical imaging, quality assurance, and more. To study this phenomenon, researchers simulated EOT devices with different array geometries and material properties. The simulation results were compared and validated with measured data. Let’s take a look at their work…

Maintaining an even temperature for buildings in hot climates often requires a lot of energy. One option for improving thermal performance is by including phase change materials (PCMs) in parts of the building. To study the effectiveness of PCMs in regulating temperature, researchers used the COMSOL Multiphysics® software to model a novel plaster that includes a PCM. They then analyzed the thermal performance of the PCM-enhanced plaster and compared the results with a reference plaster.

Nonconducting film (NCF) is an emerging underfill adhesive technology used to assemble electronic components in the microelectronics industry. Optimizing the NCF material and process can be difficult, as they must achieve a fast bonding time, high degree of cure, and correct underfill fillet shape. Achieving a successful bond depends on the interaction between the material’s chemorheology and the bonding process parameters. To understand these interactions, Veryst Engineering simulated the flow and cure on an NCF during the thermocompression bonding process.

Solar-grade silicon is becoming more popular for applications such as communications and photovoltaics. While it’s important to keep up with this growing demand, the current method of producing solar-grade silicon is energy intensive and expensive. To find a more efficient process, researchers at JPM Silicon GmbH explored a novel method using a microwave furnace. By simulating the internal processes, they aim to optimize their microwave furnace design to produce low-cost solar-grade silicon.

If bubbles in a microfluidic device become stuck, it can cause the device to malfunction. Bubble entrapment depends on several factors, including the geometry and flow characteristics of the microchannel, as well as the surface properties of its walls. To study these aspects, Veryst Engineering modeled a bubble in a microchannel using the COMSOL Multiphysics® software. Today, we look at their results, which shed light on the device geometries and contact angles that lead to bubble entrapment.

When a pipe springs a leak, it’s important to find its location with a quick and accurate method. Engineers at Echologics — a Mueller Technologies Company — use a combination of acoustic sensors and simulation applications to pinpoint such leaks. Sebastien Perrier of Echologics discussed the benefits of this approach and gave a live demonstration of an acoustics modeling app during his keynote talk at the COMSOL Conference 2016 Boston. If you missed Sebastien’s presentation, you can watch it below.

Transdermal drug delivery (TDD) patches continuously deliver drugs into the body for a certain amount of time. However, the skin is designed to keep out foreign substances, like drugs. To create a TDD patch that successfully bypasses this barrier, simulation can be used to study drug release and absorption into the skin. To analyze this process, Veryst Engineering created a TDD patch model with the COMSOL Multiphysics® software and compared the results to experimental data.

Developing a device that generates nuclear fusion would provide a nearly limitless amount of clean energy on Earth. But while work on thermonuclear fusion began in the 1950s, engineers are still trying to make this goal a reality. One approach has been to use magnetic confinement devices known as tokamaks. See why a group of engineers at MIT’s Plasma Science Fusion Center (PSFC) turned to simulation to address a key challenge in tokamak design: instability due to plasma disruptions.

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.
