Furthering the Understanding of Coronal Heating and Solar Wind Origin

Researchers from the Space Science Center at the University of New Hampshire, led by co-principal investigators Jean Perez and Benjamin Chandran, expect to arrive at new theoretical understandings in this area through their INCITE research. The team is conducting the first direct numerical simulations of AW turbulence in the extended solar atmosphere that account for the inhomogeneities in the density, flow speed, and background magnetic field within a narrow magnetic flux tube extending from roughly one solar radius to eleven solar radii. They are comparing numerical simulations conducted on Argonne Leadership Computing Facility (ALCF) supercomputers with remote observations.

Argonne Scientists Probe the Cosmic Structure of the Dark Universe

In the standard model of cosmology, dark energy and dark matter together account for 95% of the mass energy of the universe; however, their ultimate origin remains a mystery. The Argonne Leadership Computing Facility will allocate significant supercomputing resources towards unraveling one of the key puzzles—the nature of the dark energy causing the universe to accelerate its current expansion rate.

Petascale Simulations of Stress Corrosion Cracking

The performance and lifetime of materials widely used in energy and nuclear technologies are often severely limited by corrosion under stress loads. Simulations performed at the ALCF are revealing the atomistic mechanisms that control stress-induced corrosion within nuclear reactors—which is key to understanding the phenomenon, and ultimately, to developing new technologies to prevent it.
