Expansion of DOE-DOT Tight Oil Research Work

The Departments of Energy and Transportation commissioned a technical team through Sandia to examine the properties of tight crude oils as they relate to potential combustion events in the rail transport environment. Key objectives of this investigation are to characterize and define tight crude oils based on their chemical and physical properties, and identify properties [...]

Sandia’s Frontier Observatory for Research In Geothermal Energy (FORGE) Phase 1 Proposals Were Both Successful

The Department of Energy Office of Energy Efficiency and Renewable Energy’s (DOE-EERE’s) Geothermal Technologies Office (GTO) defines FORGE’s mission as “enabling cutting-edge research and drilling and technology testing, as well as to allow scientists to identify a replicable, commercial pathway to enhanced geothermal systems (EGSs).” In addition to the site itself, the FORGE effort will [...]

Sandia Researchers Are First to Measure Thermoelectric Behavior of a Nanoporous Metal-Organic Framework

Thermoelectric devices convert heat to electricity and have no moving parts, making them extremely attractive for cooling and energy harvesting applications. Thermoelectric metal-organic frameworks (MOFs) could take these advantages a step further with improved performance, smaller size and flexible designs. MOFs have a crystalline structure that resembles molecular scaffolding, consisting of rigid organic molecules linked [...]

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 [...]

Strategic Petroleum Reserve: Nitrogen Monitoring & Integrity Testing of SW Louisiana Caverns

As the US Strategic Petroleum Reserve (SPR) storage caverns age, the integrity of the cavern wells has emerged as a significant issue, which requires mitigation. SPR has been holding nitrogen on several cavern storage wells since November 2012. Pressure prediction as a function of time for WH117A. Inset shows model predictions during the nitrogen [...]

Sandians Participate in 46th Annual American Geophysical Union (AGU) Conference

Fifty-six Sandians from ten Centers joined more than 22,000 geoscience professionals, students, and academics at the December AGU Fall Meeting. Sandia staff chaired multiple technical sessions and gave dozens of presentations on topics ranging from improved climate models to performance models for underground waste storage to 3D printing and digital rock physics. Marianne Walck (Director [...]

Sandia Team Attends World Water Week in Stockholm

Stephanie Kuzio, Vince Tidwell, and Tom Lowry (all from Sandia’s Earth Systems Analysis Dept.), represented Sandia’s Water and Environment Program (part of the Sandia’s Climate & Environment Program Area) at World Water Week in Stockholm August 31–September 5th. The theme for this year’s conference was Energy and Water, and Vince Tidwell was invited to speak [...]

Sandians Published in American Chemical Society’s Environmental Science & Technology

Electricity use by water service sector and county. Shown are electricity use by (a) large-scale conveyance, (b) groundwater irrigation pumping, (c) surface water irrigation pumping, (d) drinking water, and (e) wastewater. Aggregate electricity use across these sectors (f) is also mapped. Vince Tidwell and Barbie Moreland (both in Sandia’s Earth Systems Analysis Dept.) [...]

Parallel Implementation of Smoothed-Particle Hydrodynamics Method Using LAMMPS/Trilinos

Sandia has implemented a scalable parallel capability to model polarized-fluid dynamics in micro devices driven by an electric potential. The Sandia team discretized the mathematical model (Navier-Stokes and Poisson-Bolzman equations) with an implicit smoothed-particle hydrodynamics (SPH) method. Due to the method’s particle nature, the team used the LAMMPS (Large-scale Atomic/Molecular Massively Parallel Simulator) particle library, [...]
