Optimizing Thermal Processes in Carbon Manufacturing with Simulation

Guest Bojan Jokanović July 5, 2018

Guest blogger Bojan Jokanović of SGL Carbon GmbH, one of the world’s leading manufacturers of carbon-based products, discusses the optimization of thermal processes in the carbon industry. Carbon products are used in many industries, including semiconductors, car manufacturing, ceramics, and metallurgy. Properties of graphite including high-temperature stability, good thermal and electric conducting behavior, and high chemical stability make this material unique. However, carbon manufacturing is an energy-intensive industry. We must build digital process chains to optimize processes and minimize costs.

The average human heart beats around 100,000 times in a single day. With each beat, the four valves within the heart open and close, transporting blood unidirectionally through its chambers. By simulating heart valves, medical researchers can study their behavior to address various cardiac health issues. As an example, a team from Veryst Engineering modeled a heart valve opening and closing with the COMSOL Multiphysics® software.

Guest blogger Mandar Gadgil of Noumenon Multiphysics discusses modeling phase change in a thermosiphon. Thermosiphons have been used for keeping houses warm since the 1800s. These devices use central heaters and pipe networks that carry water and steam to different rooms. The cool part (figuratively) is that no pump is needed for fluid transport — convective currents induced by the heater located at the bottom of an installation are enough. Let’s discuss modeling thermosiphons using a “pseudofluid” with temperature-dependent properties.

Today, guest blogger René Christensen of GN Hearing discusses including thermoviscous losses in the topology optimization of microacoustic devices. Topology optimization helps engineers design applications in an optimized manner with respect to certain a priori objectives. Mainly used in structural mechanics, topology optimization is also used for thermal, electromagnetics, and acoustics applications. One physics that was missing from this list until last year is microacoustics. This blog post describes a new method for including thermoviscous losses for microacoustics topology optimization.

Today, guest blogger Björn Fallqvist of Lightness by Design, a COMSOL Certified Consultant, discusses using simulation to provide insight into the mechanical behavior of cells. Biological cells are essential for life as we know it. They not only store and replicate hereditary information in the form of DNA but also are instrumental in biological processes. In most, if not all, of these processes, the mechanical behavior of cells is a main factor in ensuring normal physiological functions.

In a lineup of online shopping results, jackets labeled as being made with GORE-TEX® product technology signal “high quality” to the consumer. The company behind this technology, W. L. Gore & Associates, Inc., specializes in materials science for fabrics, medical products, and performance solutions. The companies that produce the end products rely on material that performs as expected. To accelerate their product development efforts, W. L. Gore & Associates, Inc. uses simulation, apps, and the COMSOL Server™ product.

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.

You’re listening to music when you bump into your loudspeaker, knocking it off the table. Fortunately, it still works! In his keynote presentation at the COMSOL Conference 2017 Boston, Richard Little discussed how Sonos, Inc. ensures that loudspeakers are durable enough to withstand certain stresses and how they use simulation to improve the robustness of the transducer component. If you missed his talk, you can watch the video recording below, followed by a quick summary of his presentation.

Guest blogger Linus Fagerberg from Lightness by Design picks up where he left off in his previous blog post to discuss how radiated sound depends on the shell thickness of a muffler. Here, we discuss different entities for gauging the performance of mufflers. One important parameter is the thickness of the muffler’s casing and how this affects its performance. By performing acoustic-structure interaction simulations, we can see how shell thickness affects muffler performance.

Guest blogger Linus Fagerberg from Lightness by Design returns to share a novel approach for predicting external noise generation in muffler designs. In recent years, the European Union has introduced stricter noise emission limits for road vehicles. For those designing mufflers, these limits make it important to create more efficient ways of developing and assessing the performance of their designs. At Lightness by Design, we’ve developed a novel approach that accomplishes this goal.
