Modeling Chemical Reactions: Kinetics

March 1, 2013

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.

Injectable Microbubbles in Hydrology and Healthcare

February 1, 2013

Microbubbles filled with oxygen can be injected into contaminated lakes to restore the water quality. Typically, water is purified via water-treatment plants, but this microbubble technique is both inexpensive and more environmentally-friendly in comparison. As seen in a COMSOL News 2011 article, oxygen microbubbles are a researcher’s way of copying nature’s own self-restoration mechanism for cleaning contaminated lakes.

Modeling Static Mixers

November 9, 2012

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?

The Difficulties with Working with Nanoparticles

May 21, 2012

When it comes to the design of batteries, we want to maximize charge while minimizing volume and weight. The use of nanoparticles can help achieve these goals. However, as I was just reading in one of my favorite websites, Phys.org, it is very difficult to control the material properties when working with nanostructures.
