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) […]

Investigating the Value of Simulated Wind Data for Wave Resource Characterization at US Test Sites

Sandia is cataloging wind, surface current, and wave data at US test sites to provide detailed and consistent wave-resource data that wave-energy developers can use to evaluate and compare different test sites. As part of this effort, Sandia compared National Centers for Environmental Prediction (NCEP) Climate Forecast System Reanalysis (CFSR) simulations for wind speed and […]

Sandia Funded to Model Power Pods for Utility-Scale Wave-Energy Converter

Planning an open-water test facility for utility-scale wave-energy converters (WECs) within the US requires a multifaceted approach. Concerns regarding the siting and permitting, the environmental interactions, the device performance, and the cost of the facility must all be simultaneously addressed. The DOE has started to investigate a utility-scale WEC testing facility with the recent awards […]

Wave Energy Resource Characterization at US Test Sites

Sandia is creating on an open-source catalog for wave-energy converter (WEC) developers with a detailed and consistent wave resource characterization at three US test sites the Wave Energy Test Site (WETS) in Kaneohe Bay, HI; the North Energy Test Site (NETS) offshore of Newport, OR; and a potential site offshore of Humboldt Bay, CA. Hindcast […]

Sandia Completes Hydrostructural Analysis of Ocean Renewable Power Company’s TidGen® Turbine

Sandia performed an independent hydrostructural analysis of the Ocean Renewable Power Company (ORPC) TidGen® turbine, with a focus on the bolted-joint connections. Sandia’s CACTUS hydrodynamics software was used to predict dynamic loads on the turbine, and these loads served as input to structural dynamics analysis, performed using Abaqus finite-element analysis (FEA) software. The analysis examined […]
