National Rotor Testbed Rotor Design Integrated Airfoil Performance Results

The National Rotor Testbed (NRT) team is examining the effect of airfoil choice on the final design of the new rotor for the Scaled Wind Farm Technology (SWiFT) facility. The airfoil family would ideally be designed to operate in the relevant SWiFT-scale Reynold’s number range, 1–2 million, and be experimentally verified. Two leading options have [...]

First-Ever Asian MELCOR User Group Meeting

The first-ever Asian MELCOR User Group Meeting was held in Daejeon, South Korea, from October 13–17. MELCOR is a fully integrated, engineering-level computer code whose primary purpose is to model severe-accident progression in light-water-reactor (LWR) nuclear power plants. Sandia developed MELCOR for the US Nuclear Regulatory Commission (NRC)—to treat a broad spectrum of phenomena in both [...]

Sandian Presents on PV Failure Analysis at European PV Solar Energy Conference and Exhibition (EU PVSC)

PV fault detection/monitoring system using machine-learning algorithms. A learning algorithm is trained to estimate power production based on meteorological data (irradiance, temperature, wind speed, etc.). This predic-tion is then compared to the actual power to detect various faults. Current research is focused on distinguishing different fault signatures. (Figure from Riley and Johnson, 2012) [...]

Waste Isolation Pilot Plant Accident Investigation Analysis Support

Simulation of a WIPP waste-storage barrel rupture due to an internal cook-off event. A multi-disciplinary team provided critical analysis as part of the Technical Assessment Team supporting the investigation of a radiation release at the Waste Isolation Pilot Plant (WIPP) in Carlsbad, New Mexico. Subsequent to a February 5, 2014, truck fire, a [...]

Solar Regional Test Center in Vermont Achieves Milestone Installation

Dr. Danielson and Sen. Sanders attend ribbon-cutting ceremony to commemorate the newly installed PV arrays at the Williston, Vermont, RTC site. The solar industry is now more than 60% of the way toward achieving the DOE SunShot Initiative affordability goal of $0.06 per kilowatt-hour for solar electricity. Meeting the last 40% without compromising [...]

Federal Laboratory Consortium Regional Technology-Transfer Awards Salute Innovation, Commercialization at Sandia

The Federal Laboratory Consortium (FLC) is the nationwide network of federal laboratories with more than 300 members that provides the forum to develop strategies and opportunities for linking laboratory mission technologies and expertise with the marketplace. “We are proud of this work in technology development, technology transfer, and partnerships,” said Jackie Kerby Moore, Sandia’s manager [...]

Measuring Inflow and Wake Flow Turbulence Using a Mobile-Deployed Acoustic Doppler Velocimeter

Sandia has developed a mobile acoustic Doppler velocimeter (ADV) system that characterizes inflow and wake flow velocity and turbulence around a vertical axis turbine deployed at the Roza Canal, Yakima, Washington. The ADV was mounted on a hydrofoil (see figure, left-hand panel) and deployed using either an aluminum platform mounted on a bridge (center panel) [...]

Continuous Reliability Enhancement for Wind (CREW): Project Update

During 2013, the CREW team performed an internal reassessment of their effort to identify the benchmark’s value, any data gaps, and opportunities to be better aligned with the wind industry and found that wind-plant owners and operators have been developing in-house reliability-data collection tools with similar goals to the CREW project and that the original [...]
