Optimizing the Continuous Casting Process with Simulation

Alexandra Foley | July 31, 2014

The Swiss steel company SMS Concast has been leveraging multiphysics simulation to optimize the steelmaking process of continuous casting. Through research conducted using COMSOL Multiphysics, the R&D team at SMS Concast was able to implement a new technique that allowed a steelmaking plant in Taiwan to reduce yearly CO2 emissions by about 40,000 tons.

Imagine a mode of air travel that is both fuel efficient and environmentally friendly. The mechanical modeling of torque transfer components in fully superconducting rotating machines have helped researchers draw new conclusions on how to optimize aircraft design and potentially achieve electric propulsion. A research team investigated the stress and heat distribution in these machines and presented their results at the COMSOL Conference 2013 in Boston.

There are many factors that go into designing the ideal oven — supreme cooking capability is a must, but energy efficiency and the use of materials with reduced environmental impact is also important. How can all of these different factors be combined to create an oven that is optimized for the best performance? Engineers working at Whirlpool Corporation along with the European green energy initiative, GREENKITCHEN project, found that multiphysics simulation was vital to the success of their design process.

One of the main issues with high-power electrical devices is thermal management. Together with BLOCK Transformatoren-Elektronik GmbH, we created a model using COMSOL Multiphysics simulation software that encompasses all of the important details when modeling heating of high-power electrical devices. To do so, we had to utilize high performance computing (HPC) with hybrid modeling. Here, we will discuss how to approach this real-life task with the COMSOL software.

Energy and telecom cables often journey through harsh environments to reach their destinations. Some cables are responsible for carrying high currents and must navigate in conditions that include high thermal loads, mechanical loads, and limited ventilation. We recently published a story in the IEEE Spectrum Insert, Multiphysics Simulation, explaining how the Prysmian Group, a leader in developing cable systems across many industries, has begun using COMSOL Multiphysics to improve their development process, save resources, and optimize their cable designs.

In a previous blog post, we presented the applications of conjugate heat transfer involving immobile solids. The case of immobile solids simplifies the heat equation to be solved and is often a good approximation to the temperature field. Today, we will complete the description of the physics that account for thermoelastic effects of the material when heat transfer and solid mechanics are coupled.

High temperatures can be used to destroy tumor cells, a cancer treatment known as hyperthermic oncology. Although the idea behind this treatment method has been around for some time, it wasn’t until recently that new tools and more precise delivery of heat has allowed hyperthermia to be used for cancer treatment. As hyperthermic oncology studies continue, simulation has proven a valuable tool for achieving a deeper understanding of how to deliver heat to tumors while limiting damage to healthy tissue.

The power electronics industry is responsible for products used by billions of people: smartphones, televisions, certain car parts, and even components in motors and household objects. With such a diverse array of applications, many design requirements are considered during the making of these products, including power and energy density, cost, and customer safety. Arkansas Power Electronics International (APEI), a USA-based company, is refining designs for power packaging to control thermal management in power electronics devices, increase efficiency, and lower cost.

When modeling acoustics phenomena, particularly of devices with small geometric dimensions, there are many complex factors to consider. The Thermoviscous Acoustics interface offers a simple and accurate way to set up and solve your acoustics model for factors such as acoustic pressure, velocity, and temperature variation. Here, we will demonstrate how to model your thermoviscous acoustics problems in COMSOL Multiphysics and provide some tips and resources for doing so.
