When Stars Align (and Collide): A Historic Gravitational Wave Discovery

October 17, 2017

Imagine going from only reading textbooks with no pictures to seeing a 3D movie. Thanks to a 2017 discovery, astrophysicists experienced a comparable improvement in how they see the universe.

What Is the Physics Behind a Counterweight Trebuchet?

October 11, 2017

A counterweight trebuchet, a siege weapon commonly seen in movies set in the Middle Ages and fantasy worlds, also happen to be an interesting multibody dynamics problem.

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®.

Happy Birthday, George Westinghouse

Guest blogger Linus Fagerberg from Lightness by Design follows up a previous post with a discussion of one design consideration for the radiated sound in a muffler design: shell thickness.

Improving IFE Target Fabrication with a Droplet Microfluidics Method

September 29, 2017

A common joke is that fusion energy is 30 years away, and always will be. Researchers are using simulation to tackle the challenges involved with of inertial fusion energy target production.

Computing Porosity and Permeability in Porous Media with a Submodel

September 27, 2017

Porous materials have complex geometries and may therefore be difficult to model. Setting up a microscale submodel is a useful approach to find the porosity and permeability of the medium.
