In chemical reaction engineering, simulations are useful for investigating and optimizing a particular reaction process or system. Modeling chemical reactions helps engineers virtually understand the chemistry, optimal size and design of the system, and how it interacts with other physics that may come into play. This is the first of a series of blog posts on chemical reaction engineering, and here we will have a look at the initial stages of modeling the application: the chemical reaction kinetics.

Electrodeposition is the process of making a substance adhere to an object through electrochemical reactions. Sometimes the substance is available in the solution form and other times it is a solid object too, and needs to undergo electrochemical reactions in order to dissolve into solution; often as part of the electrodeposition process. Electrodeposition can be an important part of the refining process of certain metals, such as copper, silver, and gold and is often referred to as electrorefining or electrowinning. […]

On Friday I wrote about designing safer lithium-ion batteries, and showed you a few resources for helping people do just that. Now I’d like to show you a lithium-ion battery model and briefly run through how it can be created in COMSOL Multiphysics in three sequential studies.

Unless you live under a rock, you’ll have heard lithium-ion batteries mentioned a lot lately. Last week in Boston, a lithium-ion battery caught fire in the new Boeing 787 Dreamliner, forcing them to ground all Dreamliner planes until further notice. This type of battery makes it possible to pack lots of power into a small package. What can be done to make it operate safely?

A mixer that doesn’t move may sound like an oxymoron, but it’s not. Used in various chemical species transport applications, static mixers are inexpensive, accurate, and versatile. Still, there is always room for improvement. Optimizing the design of static mixers calls for computer modeling, but traditional CFD methods may not be the best way to model these mixers. How do these motionless mixers work and how can their performance be simulated?

COMSOL has had a great relationship with Emeritus Professor Bruce Finlayson of the University of Washington. I first saw him back in 2002 at an American Institute of Chemical Engineering (AIChE) meeting where he gave a presentation on the use of modeling in chemical engineering education. As a former President of AIChE and with a resumé covering some of the leading research and industrial advances within chemical engineering, I was quite intrigued by him taking the time and effort to […]

It has always been the flexibility of COMSOL Multiphysics that attracted people from the fuel cell and battery industries. The other software back in the day did not adequately support the ability to model the electrochemical equations that were required to properly describe the behavior of their appliances. As we noticed that more and more of these vendors were interested in COMSOL Multiphysics, this led to a great increase in COMSOL’s knowledge and ability to model these applications. For example, […]

I was just reading one of my favorite sites, phys.org, about the difficulties of working with nanostructures. In the world of batteries, you want to maximize charge, while minimizing volume and weight. This means that the nano-world is starting to take hold, but, as has been discovered with many other applications where nanotechnology is being applied, it is very difficult to control the material properties in this world.

It’s an exciting time here as we’re starting to release a series of resources for COMSOL users and people interested in modeling and optimizing multiphysics and other engineering applications. This will be done as a set of CDs that will contain animated videos summarizing the features in COMSOL’s suite of products, and videos showing model examples being built. Also included on this CD will be white papers, conference articles, and reports of real-life situations where modeling has been applied.

We’re increasing the electrochemical family of products with the next version of COMSOL. Joining the Batteries & Fuel Cells and Electrodeposition Modules will be the Corrosion Module. This will allow for the modeling of all types of electrochemical corrosion (galvanic, pitting, etc.) as well as corrosion protection. This has been an exciting development and is the response to a number of COMSOL users who have requested it.
