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 […]

Understanding Seasonal Effects of WEC Operation using the SNL-SWAN Wave Model Application

Sandia researchers are investigating the seasonal effects of a wave-energy converter (WEC) array on nearshore wave propagation using SNL-SWAN. WECs were simulated as obstacles with frequency-dependent transmission coefficients that were determined based on the incoming wave height and period. The research team created frequency distributions of seasonal wave parameters (significant wave height, peak wave period, […]

Sandia, NREL Release Wave Energy Converter Modeling and Simulation Code: WEC-Sim

Sandia and the National Renewable Energy Laboratory (NREL) are partnered in a three-year project to develop and verify WEC-Sim, an open-source numerical modeling tool to analyze and optimize wave-energy converters (WECs). On June 30th, the team publicly released Version 1.0 of WEC-Sim for free access to any interested users and code developers. WEC-Sim has the […]

Sandian Re-Elected as President of the Association for Computing Machinery Special Interest Group on Graphics and Interactive Techniques

Jeff Jortner (in Sandia’s Scalable Modeling & Analysis Systems Dept.) has been re-elected for another three-year term as the President of the Association for Computing Machinery (ACM) Special Interest Group on Graphics and Interactive Techniques (SIGGRAPH). ACM is the world’s largest educational and scientific comput­ing society and delivers resources that advance computing as a science […]

Sandia Vertical-Axis Wind-Turbine Research Presented at Science of Making Torque from Wind Conference

In June, Brian Owens (in Sandia’s Analytical Structural Dynamics Dept.) and Todd Griffith (in Sandia’s Water Power Technologies Dept.) traveled to DTU Lyngby (Technical University of Denmark: Copenhagen, Denmark) to present Sandia research on deep-water multiple-megawatt vertical-axis wind turbines (VAWTs). High tip-speed ratios, low frequency structural vibration modes, and flexible blades of multiple-megawatt VAWTs can […]
