Modeling Adsorption at Surfaces in COMSOL Multiphysics®
What is adsorption? Learn the theory behind this chemical engineering phenomenon as well as how to model the process at surfaces in the COMSOL® software.
Model Deforming Objects with the Arbitrary Lagrangian-Eulerian Method
The combined efforts of Leonhard Euler and Joseph-Louis Lagrange inspired the arbitrary Lagrangian-Eulerian (ALE) method, which we can use to model deforming objects.
Modeling Surface Reactions in Porous Media and Reactive Pellet Beds
Reactive pellet beds have complex local geometries and undergo microscopic diffusion, but there is a way to simply and accurately simulate these devices in COMSOL Multiphysics®.
Pulsed Electrochemical Machining: A Multiphysics Model
Industries that manufacture metal parts are concerned with precision machining and quality of surface finish. Optimizing the pulsed electrochemical machining process can improve these factors.
Introduction to Modeling Surface Reactions in COMSOL Multiphysics®
Bioengineers and electrochemists will appreciate this detailed introduction to modeling surface reactions with the COMSOL® software.
Model Electrodes with Nonideal Connectivity in Corrosion Analyses
Learn the appropriate boundary conditions for performing a corrosion analysis in which an electrode is connected to an external short circuit.
Electrochemical Impedance Spectroscopy: Experiment, Model, and App
Experience the phenomenon of electrochemical impedance spectroscopy (EIS) in 3 ways: experiment, model, and simulation application.
How to Model Short Circuits in Lithium-Ion Batteries
When the chemical energy stored in a lithium-ion battery is lost as heat, rather than being used to power a device, it is known as a short circuit. Learn how to model this phenomenon.
Protein Adsorption: Batch and Space-Dependent Modeling
We take you step by step through developing a detailed protein adsorption reactor model. We start with a simple, perfectly mixed batch reactor and move onto space-dependent modeling.
Do Hybrid and Electric Vehicles Have the Pulling Power?
Designers of hybrid and electric vehicles need to have a good understanding of how the car’s lithium-ion battery operates to ensure both performance and safety.
Bringing Multiphysics into Architecture
From the Sydney Opera House in Australia to the Vdara® hotel in Las Vegas, we discuss the potential applications of simulation for architectural development and introduce LiveLink™ for Revit®.
Modeling Electrochemistry for Managing Diabetes
An estimated 350 million people worldwide are living with diabetes. By modeling electrochemical processes, biomedical engineers can analyze and optimize the glucose sensing process.
Electroplating: How the U.S. Mint Makes a Penny
Did you know that a penny actually doesn’t contain a lot of copper? Learn about how the U.S. Mint makes pennies through the process of electroplating, which can be studied with chemical modeling.
Theory of Current Distribution
Here, we discuss one of the building blocks that make up hybrid parallel computing, namely shared memory computing, as well as when and how to use shared memory with COMSOL Multiphysics®.
Coupling Transport and Solid Mechanics Models for Better Puffed Rice
In my work at COMSOL, it’s always interesting to see how broad the field of heat transfer can be. Far from being limited to steel ingots and CPU fans, researchers often use COMSOL Multiphysics to study heat transfer in food manufacturing. One good example of this is the study of thermal and mechanical effects in the production of puffed rice, which was presented at the COMSOL Conference 2013 in Boston.
A Lithium-ion Battery Analysis at INES-CEA
During my time as a PhD student, a blue “Chemical Landmark” plaque was fitted to the building a couple of hundred yards down the road from my lab. The plaque commemorates the achievements of the researchers who made the lithium-ion (Li-ion) battery viable. Whether or not you know about the electrochemistry of rechargeable lithium-ion batteries, you probably rely on one. We carry them around in our phones and laptops, and ride in cars and planes that use them for power. […]
Modeling Electroanalysis: Cyclic Voltammetry
If you’re not an electrochemist, chances are you’ve never come across cyclic voltammetry. But look at any electrochemical journal, conference proceedings, or company website for manufacturers of electrochemical sensors. Somewhere near the front, you’ll see a distinctive “double-peaked” graph.
