Simulating sneezes and coughs to show how COVID-19 spreads
May 11, 2021 • ALBUQUERQUE, N.M. — Two groups of researchers at Sandia National Laboratories have published papers on the droplets of liquid sprayed by coughs or sneezes and how far they can travel under different conditions. Both teams used Sandia’s decades of experience with advanced computer simulations studying how liquids and gases move...

Finding fire and ice: Modeling the probability of methane hydrate deposits on the seafloor
March 17, 2021 • RALEIGH, N.C. — Methane hydrate, an ice-like material made of compressed natural gas, burns when lit and can be found in some regions of the seafloor and in Arctic permafrost. Thought to be the world’s largest source of natural gas, methane hydrate is a potential fuel source, and if it...

Sandia National Laboratories researchers used advanced computer models to predict the like­lihood of finding methane hydrate, an ice-like material made of compressed natural gas that burns when lit.

Thin explosive films provide snapshot of how detonations start
March 4, 2021 • ALBUQUERQUE, N.M. — Using thin films — no more than a few pieces of notebook paper thick — of a common explosive chemical, researchers from Sandia National Laboratories studied how small-scale explosions start and grow. Sandia is the only lab in the U.S. that can make such detonatable thin films....

Modeling terrorist behavior with Sandia social-cultural assessments
January 24, 2019 • ALBUQUERQUE, N.M. — Part of what makes terrorists so frightening is their penchant for unpredictable, indiscriminate violence. One day they could attack a global financial center. And the next they could hit a neighborhood bike path. A team of Sandia social-behavioral scientists and computational modelers recently completed a two-year effort,...

International corrosion society elects first Sandia fellow
June 4, 2018 • ALBUQUERQUE, N.M. — A decade ago, while studying potential corrosion of containers for the proposed Yucca Mountain nuclear waste repository in Nevada, Sandia National Laboratories materials scientist David Enos designed an intricate solution to a sticky problem. Computer simulations showed the likelihood of unusually high heat and humidity deep inside...

Infrastructure optimization tool from Sandia helps design future bases
November 6, 2017 • ALBUQUERQUE, N.M. — Where do you get your water? How do you generate electricity to cook your food and keep it fresh? What happens to your waste after you toss it or flush it? For soldiers overseas, the answers to questions about basic facilities and services are vital. Since 2013,...
