Modeling Cables in COMSOL Multiphysics®: 6-Part Tutorial Series

Brianne Costa December 29, 2017

Want a roadmap to modeling cables? We have a six-part tutorial series for you. The Cable Tutorial Series shows how to model an industrial-scale cable in the COMSOL Multiphysics® software and add-on AC/DC Module, and also serves as an introduction to modeling electromagnetic phenomena in general. The numerical model is based on standard cable designs and validated by reported figures. Keep reading for a sneak peek of what you’ll learn when you roll up your sleeves and start the series.

When looking through scientific papers, it’s common to see colorful results. Although aesthetically pleasing to some, these results can be difficult to interpret for engineers with color vision deficiency (CVD). You may think that presenting results in grayscale could help, but humans are less able to discern between different shades of gray. So what’s the best option here?

You can easily describe composition- and temperature-dependent fluid properties using the thermodynamic properties database, available as of version 5.3a of the COMSOL Multiphysics® software. For reacting systems, the database computes enthalpy of formation and enthalpy of reaction. For fluid flow and heat and mass transfer, the database can compute viscosity, density, heat capacity, thermal conductivity, and diffusivity of liquids and gases. For systems with several phases, the thermodynamic properties database computes the composition of the phases at equilibrium.

You’re standing in a lab full of beakers containing different colored liquids. While it may look like something out of a cartoon, this is a lab for researching vanadium redox flow batteries (VRFBs). Unlike conventional batteries, the chemical energy in VRFBs is contained in liquid electrolytes that are stored in external tanks and pumped through the cell to convert to or from electrical energy. By advancing VRFB designs, engineers can improve grid energy storage and the reliability of renewable energy.

In Part 2 of our blog series on how to model irregular shapes in the COMSOL Multiphysics® software, we focus on how to create a surface of an irregular shape based on elevation data stored in various formats such as text, an image, or a DEM file. This approach is best suited for data where the height (or elevation) is a function of x- and y-coordinates.

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.

It’s a bird, it’s a plane, it’s…the future of data sharing? Satellites orbiting Earth have the potential to revolutionize how we collect and share information. Instead of wired or wireless data networks, satellites could form the basis of an Internet of Space (IoS) to connect even the most remote locations.
