Todd Griffith, Brian Owens, and Phillip Richards traveled to Copenhagen, Denmark for the Science of Making Torque from Wind Conference (June 18 to 20, 2014).Three proceedings papers were presented. Phillip Richards (a PhD student at Georgia Tech) gave an oral presentation for the paper titled “High-fidelity Modeling of Local Effects of Damage for Derated Offshore Wind Turbines.” The paper was co-authored by Todd Griffith and Professor Dewey Hodges in support of the SNL Offshore Structural Health and Prognostics Management project.
Several blade concepts could work on multi-megawatt VAWTs. The concepts were presented for Aero-elastic Stability Analyses.
Brian Owens presented a poster co-authored by Todd Griffith titled “Aero-elastic Stability Investigations for Large-scale Vertical Axis Wind Turbines”, which summarized aero-elastic stability estimates for large-scale 5 MW vertical-axis wind turbines (VAWTs). A design study on aeroelastic stability of very large VAWTs was conducted using an enhanced version of the Offshore Wind Energy Simulation Toolkit for VAWTs. A figure from that poster may be found in the first image here.
A third paper, co-authored by Sandia’s Matt Barone with other researchers from TU-Delft, DTU-Wind, and Areva, entitled “Comparison of Aerodynamic Models for Vertical Axis Wind Turbines”, was presented by Carlos Simao Ferreira of TU-Delft.This paper provided a comparison of six aerodynamic codes for VAWTs including the early-developed stream tube models and more recent codes under development by the teams.
Sandia presentations were made at the 2014 Torque Conference in Denmark.
The Torque Conference, which is organized every other year by the European Academy of Wind Energy, included about 320 attendees and ~190 proceedings papers (~80 oral presentations and ~110 poster presentations). The 2016 Torque event will take place in Munich, Germany. Reach D. Todd Griffith at (505) 845-2056.
