CFD-Populated Empirical Turbine Wake Model

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). Initial efforts were focused on […]

Floating Oscillating Water Column Reference Model Completed

The DOE-supported Reference Model Project was developed to provide publicly available technical and economic benchmarks for a variety of marine energy converters. The final reference model, an oscillating water column (OWC) device, has been completed. Key aspects of the Backward Bent Duct Buoy (BBDB) have been modeled and documented for public release. This model has […]

Developing a Fast-Running Turbine Wake Model

On December 4, 2014, in Energy, News, News & Events, Renewable Energy, Water Power

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, Sandia has begun implementing parametric […]

Final FY14 Measurement Campaign in Roza Canal, Yakima, Washington

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 (in Sandia’s Water Power Technologies Dept.) and Derek Belka (a Water Power Technologies Dept. summer intern student) joined […]

Inter-Agency Agreement Signed between DOE’s Wind and Water Power Program and Carderock

The Department of Energy (DOE) has launched a multiple-year effort to validate the extent to which control strategies can increase the power produced by resonant wave-energy converter (WEC) devices. Many theoretical studies have shown a promise that additional energy can be captured by controlling the power-conversion chains of resonant WEC devices. The numerical models employed […]
