Modeling Adsorption at Surfaces in COMSOL Multiphysics®

January 26, 2018

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

January 17, 2018

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

October 10, 2017

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

September 5, 2017

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.

Bioengineers and electrochemists will appreciate this detailed introduction to modeling surface reactions with the COMSOL® software.

Model Electrodes with Nonideal Connectivity in Corrosion Analyses

March 14, 2017

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

February 9, 2017

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

October 25, 2016

A short circuit in a battery is bad news: the chemical energy stored in the battery is lost as heat, rather than being used to power a device. Short circuits create intense heat, which can degrade battery materials or lead to fires or explosions due to thermal runaway. To avoid conditions that lead to short circuits in devices and ensure that short circuits do not cause unsafe operating conditions, we can study lithium-ion battery designs with the COMSOL Multiphysics® software.
