CFD-Populated Empirical Turbine Wake Model
News Article, February 24, 2015 • The DTOcean team is developing a fast-running, easy to use current-energy capture (CEC) array spacing tool that considers tidal array performance vs efficiency. In support of this effort, Sandia has been assisting in developing the device wake modeling submodule that determines a tidal turbine’s wake properties (i.e., wake growth and dissipation)....

Developing a Fast-Running Turbine Wake Model
News Article, December 4, 2014 • As part of the international collaboration for DTOcean, a project aimed at accelerating the industrial development of ocean-energy power-generation knowledge and providing design tools for deploying the first generation of wave and tidal energy converter arrays, Sandia is developing a fast-running current energy converter (CEC) wake-interaction model. Toward this end,...

Final FY14 Measurement Campaign in Roza Canal, Yakima, Washington
News Article, December 4, 2014 • Uncertainty exists regarding the effects on local water operations of deploying a current energy converter (CEC) turbine in an irrigation canal for the purposes of producing electricity via the canal's flowing water. Budi Gunawan and Guild Copeland and Derek Belka joined a team from the US Bureau of Reclamation (USBR)...

Floating Oscillating Water Column Reference Model Completed
News Article, February 24, 2015 • The floating oscillating water column reference model (RM6) backward bent duct buoy (BBDB) device design and dimensions and Wells turbine schematic. The width of the device (not shown) is 27 m. The DOE-supported Reference Model Project was developed to provide publicly available technical and economic benchmarks for a variety of...

National Rotor Testbed Rotor Design Integrated Airfoil Performance Results
News Article, February 24, 2015 • 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...

Sandia and Partners Complete Phase I of a Vertical-Axis Deep-Water Offshore Turbine Study
News Article, December 3, 2014 • Sandia and partners from the University of Maine, Technical University of Delft, Iowa State University, TPI Composites, and Texas A&M University have completed the first phase of a project to explore the feasibility of large-scale vertical-axis wind turbines (VAWTs) for deep-water offshore locations. The results of this conceptual study show...
