Upcoming Release of the University of Minnesota’s Virtual Wind Simulator

Large-eddy simulation (LES) of wind farms with wind-turbine parameterization is emerging as a powerful tool for improving existing wind farm performance and lowering maintenance costs—and assessing the potential sites for installing wind farms. Sandia is working with the University of Minnesota (UMN) St. Anthony Falls Laboratory to document and prepare UMN’s offshore version of the [...]

Sandia Modifies Delft3D Turbine Model

Delft3D is a state-of-the-art, open-source hydrodynamics software suite capable of modeling hydrodynam­ics, sediment transport, and water quality in rivers, lakes, estuaries, and coastal environments. Delft3D was developed by the Dutch company, Deltares. Because it is actively developed and maintained and because it is held in high regard by researchers and practitioners alike, Sandia is developing [...]

Sandia Wins Funding for Programming In Situ Data Analysis/Visualization

Sandia was recently awarded DOE Advanced Scientific Computing Research (ASCR) funding to develop a framework for in situ data management, analysis, and visualization. Sandia’s approach provides a mechanism for specifying the structure and use of data, decouples code specification from optimization, and facilitates the expression of complex scientific workflows—thereby enabling scientists to develop high-performance, portable codes [...]

Sandia Participates in Office of Science’s National Science Bowl

The Department of Energy Office of Science’s National Science Bowl® (NSB) is a nationwide academic competition that tests middle and high school student teams’ knowledge in all areas of science and mathematics. The DOE created the National Science Bowl® in 1991 to encourage students to excel in mathematics and science and to pursue careers in [...]

Statistical Mechanics with Density Functional Theory Accuracy

Density Functional Theory (DFT) calculations allow the accurate determination of ground state and transition state energies but require thousands of processing hours for each structure. Monte-Carlo (MC) calculations allow the determination of initetemperature thermodynamic and kinetic properties of disordered systems but require energy evaluations for millions or billions of structures. In a Center for Integrated [...]

High Fidelity Evaluation of Tidal Turbine Performance for Industry Partner

High performance computing at Sandia National Laboratories is playing a key role in the U.S. Department of Energy’s Wind and Water Power Technology Office mission of advancing the commercialization of tidal energy converters; by improving their power performance and reducing their levelized cost of energy below the local “hurdle” price at which they can compete [...]

Cryogenic and Fire Damage Analysis on Liquefied Natural Gas Ships

Liquefied Natural Gas (LNG) is transported around the globe in ships the size of modern aircraft carriers, carrying as much as 75 million gallons of LNG or the equivalent of over 6 billion cubic feet of natural gas. LNG is transported in multiple cargo tanks at cryogenic temperatures of about -250 °F. Because of their [...]

Unique High Strength, Olecularly Thin Nanoparticle Membranes

Thin membrane films composed of a single layer of inorganic nanocrystal cores encoded with organic ligands are currently of great interest for a range of applications from nanosieves to electric, magnetic, or photonic devices and sensors. While these membranes have been found experimentally to be flexible yet surprisingly strong under indentation, the underlying microscopic origin [...]
