Li-Ion Battery: Heterogeneous Alternative to the Newman Model

April 13, 2016

When analyzing lithium-ion battery designs, is it better to use the Newman model or a detailed, heterogeneous geometric model? Find out in this comprehensive blog post…

Free Surface Computations in Mixers and Rotating Machinery

January 26, 2016

Learn different approaches for performing free surface computations in mixers and rotating machinery using COMSOL Multiphysics® and the add-on CFD Module and Mixer Module.

Simulate Three-Phase Flow with a New Phase Field Interface

December 16, 2015

The Three-Phase Flow, Phase Field interface, used for modeling separated three-phase flow, computes the shape of the interfaces between the 3 phases and accounts for interactions with walls.

Does the Current Flow Backwards Inside a Battery?

November 25, 2015

What happens inside a battery? Does the current flow from negative to positive electric potential? Here, we explain the potential profile inside a battery during discharge and recharge.

Intro to Optimizing Mixer Design by Creating an App

July 6, 2015

By building a simulation app to study mixer designs, you can easily test the influence that the vessel, impeller, and operational conditions have on the design’s mixing efficiency.

Sensing the Bio in Biosensor Design with a Simulation App

May 12, 2015

The Biosensor Design demo app predicts the results from measurements of a biomolecule’s concentration (or activity) from an understanding of this molecule’s attachment to an enzyme.

Parallel Universes, Schrödinger, Hawking, Borges, and One Direction

May 7, 2015

“It would not be beyond the realms of possibility that somewhere outside of our own universe lies another different universe — and in that universe, Zayn is still in One Direction.”

Why Car Batteries Perform Poorly in Cold Weather

February 5, 2015

Have you ever gone to start your car on a cold winter morning and nothing happens? The battery’s ability to convert chemical energy into electrical energy can be affected by low temperatures.
