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.

We have all experienced the boredom and frustration of being stuck in a traffic jam. Very often, traffic congestion comes and goes for no obvious reason. Employing the analogy to gas dynamics, we can now simulate traffic flow using the equation-based modeling capabilities of COMSOL Multiphysics and gain a better understanding of why congestion happens.

In a previous blog entry, we discussed the join feature in COMSOL Multiphysics in the context of stationary problems. Here, we will address parametric, eigenfrequency, frequency domain, and time-dependent problems. Additionally, we will compare and contrast the built-in with and at operators versus solution joining.

Modular orthopedic devices, common in replacement joints, allow surgeons to tailor the size, material, and design of an implant directly to a patient’s needs. This flexibility and customization is counterbalanced, however, by a need for the implant components to fit together correctly. With parts that are not ideally matched, micro-motions and stresses on mismatched surfaces can cause fretting fatigue and corrosion. Researchers at Continuum Blue Ltd. have assessed changes to femoral implant designs to quantify and prevent this damage.

Researchers from AltaSim Technologies presented a paper at last year’s COMSOL Conference in Boston sharing their analyses on Mie scattering of electromagnetic waves and how they compare to the Mie solution.

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.

In the 2012 edition of Multiphysics Simulation, we featured an article about modeling spinal cord stimulation to determine the effect that scar tissue can have on electrical current distribution during the treatment of chronic pain. Recently, the full-length paper by Beth Israel Deaconess researchers Jeffrey Arle, Kris Carlson, Longzhi Mei, and Jay Shils was published in the journal Neuromodulation.

Topological optimization is routinely used in the design and refinement of microfluidics devices. The process also comes in handy for modeling a Tesla microvalve.

In chemistry, separation using differences in migration patterns plays an important role in understanding the properties of different chemical species. To help identify small chemical differences between molecules, researchers use a type of electrophoresis known as isoelectric focusing. With the use of an applied electric potential, this technique helps to define and separate molecules based on their varying isoelectric points. Let’s take a closer look at this separation method.

Professional baseball pitchers are able to make a baseball move left, right, down, and even up (sort of) to get it by the opposing batter. The physics behind this can be explained by the Magnus effect.
