Try pouring some wine into a glass. Don’t drink it yet — this is a scientific experiment. When you hold up your glass, you’ll see what look like teardrops running down the sides. These tears of wine are caused by the Marangoni effect, which describes a mass transfer along the surface of two fluid phases caused by surface tension gradients along the interface between the two phases (for example liquid and vapor).

Behind the wheel of a car is not the ideal place to discover that the steering wheel is defective. That’s why special precautions are taken during the manufacturing process. The carefully controlled cooling of an injection mold ensures that whatever the product may be, its standards are up to par. Here, we use the Non-Isothermal Pipe Flow interface with the Heat Transfer in Solids interface to study the cooling path of an injection mold for a polyurethane car steering wheel.

We often need to work with experimental data in COMSOL Multiphysics, usually to represent material properties or other inputs to our model. However, experimental data is often noisy; it contains experimental errors that we do not want to introduce into our simulations. In this blog post, we will look at how to fit smooth curves and surfaces to experimental data using the core functionality of COMSOL Multiphysics.

Want to share your simulations with the world or simply your own team? After you build an application with the Application Builder in the COMSOL Multiphysics® software, you can share your app using a COMSOL Server™ license with anyone from colleagues to customers. Here is your introduction to COMSOL Server™ — what it is, why to use it, and a brief overview of how to get started.

The biological and chemical processes behind the development of biopharmaceuticals have an important effect on product quality. With its ability to deliver quick results at a lower cost, simulation is a valuable resource in studying and optimizing these techniques. Learn how COMSOL Multiphysics can benefit your modeling of biopharmaceutical processes.

Today, we welcome a new guest blogger, Alexandre Oury of SIMTEC. He discusses the analysis of current distributions in a molten salt electro-refiner. In a webinar highlighting electrochemical recycling processes, SIMTEC presented a computational approach for predicting current distributions in a molten salt electro-refiner. The three main types of current distribution (primary, secondary, and tertiary) were treated, with a particular emphasis on the first two types. Using COMSOL Multiphysics, we implemented primary and secondary current distributions in an electrolysis cell.

Gustav Robert Kirchhoff was a German physicist famous for his vast contributions to the study of spectroscopy, electrical circuits, thermochemistry, and more. Kirchhoff developed laws and theories fundamental to electrical engineering, heat capacity in chemical reactions, and the composition of light emission from incandescent objects. He even helped discover two new elements! In honor of what would have been his birthday, here is a look at Kirchhoff’s legacy.

Conserving and restoring art requires a balance between maintaining the quality of the work and respecting the artist’s initial creation. Advancing technologies now offer less invasive ways of analyzing artwork and bringing pieces back to their original condition. Since 2015 is the Year of Light, let’s explore how light can be used to conserve and restore paintings.
