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 […]

Sandia Publishes Five Reports on the Environmental Effects of Wave-Energy Converters

Since 2010, Sandia has been studying changes in wave propagation due to the operation of wave-energy converter (WEC) arrays. This work has primarily focused on applying and enhancing the-open source spectral wave model SWAN (Simulating WAves Nearshore). The five recently published SAND reports focus on applying SWAN and a modified version known as SNL-SWAN, which […]

Numerical Simulations of Hydrokinetics in the Roza Canal, Yakima Washington

Sandia completed two performance-testing studies for hydrokinetic canal effects at Roza Canal in Yakima, Washington. Sandia National Laboratories’ Environmental Fluid Dynamics Code (SNL-EFDC) was used to model the canal and the current-energy-capture device. The first was an evaluation of different grid sizes and refinements to determine an appropriate grid for future modeling efforts. The second […]
