What Is the Physics Behind a Counterweight Trebuchet?
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
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
If you’ve ever ridden on a train or used electricity, than you have American inventor George Westinghouse to thank. Learn about how he changed the way we think about and use alternating current.
Analyzing Kelvin Probe Designs with COMSOL Multiphysics®
Kelvin probes, a type of MEMS technology, provide a nondestructive and contact-free way to measure the work function differences of various material combinations.
Evaluating the Effect of Shell Thickness on Muffler Performance
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
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
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.
Analyze the Electrodynamics of a Magnetic Power Switch via Simulation
