Why Wolfspeed Builds Apps with COMSOL Multiphysics

Bridget Cunningham | November 3, 2015

Silicon chips have been the foundation of power electronics over the years. However, as more applications are using increasingly higher amounts of electrical power, silicon has begun to reach its limits. Wide band gap semiconductors offer an opportunity to surpass these confines, operating at high frequencies, voltages, and temperatures. Looking to optimize their development of wide band gap solutions, engineers at Wolfspeed utilized the power of the Application Builder within COMSOL Multiphysics.

Keeping buildings cool in the summer and warm in the winter is a major drain on energy resources. In search of a more cost-effective and energy-efficient way to heat and cool buildings, researchers at Fraunhofer ISE continuously work to develop adsorption-based systems that run on solar energy, natural gas, and industrial waste. Using COMSOL Multiphysics® simulation software, the team investigates the adsorption process, heat exchanger design, and numerous other systems that affect their innovative developments in adsorption technology.

Biofuels are recognized as a valued source of renewable energy, with applications ranging from heating buildings to powering transportation. Increasing the availability of these fuels requires an understanding of the processes behind biomass conversion. With the help of COMSOL Multiphysics® simulation software, researchers at NREL are seeking to optimize such processes, making biofuel conversion more efficient and cost-effective.

You may know of Boreas, the Greek god of North Wind, but did you know that it’s also the name of a German team for Formula 1 in schools? This is no coincidence; it describes their strong will to develop race cars that are “as fast as a storm”. With this spirit and COMSOL Multiphysics, the team won several qualifying races, reached third place in the 2014 world finals, and was honored with the innovation award for Research and Development.

Solar energy is created by combining sunlight with a semiconducting material, often silicon. But solar, or photovoltaic, cells require such a high-quality silicon that the manufacturing process is complicated and costly. As a photovoltaic material producer and furnace manufacturer, EMIX turned to COMSOL Multiphysics® simulation software to optimize their cold crucible continuous casting (4C) process and create the silicon needed for a more efficient solar-powered world.

Today we welcome guest blogger René Christensen from Dynaudio A/S. When evaluating loudspeaker performance, dips and/or peaks in the on-axis sound pressure level can be a result of an unfortunate distribution of phase components. To overcome this, we use a phase decomposition technique that splits a total surface vibration into three components depending on how they contribute to the sound pressure in an arbitrary observation point; either adding to, subtracting from, or not contributing to the pressure.

Do you drool at the very mention of chocolate? If so, you’re a “chocoholic” like me, and Nestlé’s Kit Kat® bar is one of my favorites. For 80 years, people around the globe have devoured this four-piece delight. To ensure every bar of chocolate produced has the same consistency, texture, and taste, the engineers at Nestlé’s Product Technology Centre in York, UK (PTC York) are using simulation to optimize the Kit Kat® bar manufacturing process.

3D printing has emerged as a popular manufacturing technique within a number of industries. The growing demand for this method of manufacturing has prompted greater simulation research behind its processes. Engineers at the Manufacturing Technology Centre (MTC) have identified their customers’ interest in a particular additive manufacturing technique known as shaped metal deposition. By building a simulation app, the team is better able to meet the demands of their customers while delivering more efficient and effective simulation results.

Today, we welcome guest blogger William Vetterling of ZINK Imaging to the COMSOL Blog. If you read the 2015 edition of COMSOL News, you may have seen my review of the newly released Application Builder. In that review, I shared an example of a simple thermal model of an IR microscope that we had created a year earlier for use in our laboratory at ZINK Imaging. Now I will share how we turned that model into an app.

At Boeing, innovation comes in the form of modern aircraft such as the 787 Dreamliner, whose body is made up of over 50% carbon fiber composite. While incredibly lightweight and strong, such aircraft composites are not inherently conductive, thus requiring additional protective coatings to mitigate lightning strike damage. Here, we describe how multiphysics simulation is used to evaluate thermal stress and displacement in the protective coatings that undergo temperature fluctuations associated with the typical flight cycle.

Previous work on cloaking for flexural waves in elastic plates presented limitations and near invisibility. Now, a research group in Europe has figured out a new theoretical framework to both overcome the limitations and achieve exact cloaking for flexural waves in Kirchhoff-Love plates. To visualize and test the quality of the cloak, they ran COMSOL Multiphysics simulations.
