GM Revs up Diesel Combustion Modeling on Titan Supercomputer

https://vimeo.com/260126956 Most car owners in the United States do not think twice about passing over the diesel pump at the gas station. Instead, diesel fuel mostly powers our shipping trucks, boats, buses, and generators—and that is because diesel engines are about 10 percent more fuel-efficient than gasoline, saving companies money…

New Discoveries Within ‘SIGHT’

SIGHT visualization from a project led by University of Virginia’s Leonid Zhigilei to explore how lasers transform metal surface. At the home of America’s most powerful supercomputer, the Oak Ridge Leadership Computing Facility (OLCF), researchers often simulate millions or billions of dynamic atoms to study complex problems in science and…

The Shape of Melting in Two Dimensions

https://vimeo.com/201923842 Snow falls in winter and melts in spring, but what drives the phase change in between? Although melting is a familiar phenomenon encountered in everyday life, playing a part in many industrial and commercial processes, much remains to be discovered about this transformation at a fundamental level. In 2015,…
