Development And Testing Of A 1:70 Scale Model Wind Turbine Of The Iea Reference 15 Mw Floating Offshore System, Amber Parker

Electronic Theses and Dissertations

This thesis presents the development of a 1/70th scale performance-matched wind turbine intended for wind and wave basin model testing of commercially viable floating wind turbine structures based off of the International Energy Agency (IEA) Wind 15 MW design. The focus of this demonstration is to test active blade pitch response controls and to provide an experimental dataset for use by modelers and industry for future turbine improvements. Future research is planned to test the turbine in conjunction with an actively damping hull to test the interactions between the two control systems.

Outlined in this thesis are the methods of …

Design, Optimization, And Testing Of A Cross-Flow Tidal Turbine, Megan Colleen Swanger

Electronic Theses and Dissertations

This thesis is a summary of testing conducted with a Darrieus style cross-flow tidal turbine. Many locations around the world have locations suitable for tidal turbine energy, including the Cobscook Bay in Eastport, Maine. Cross-flow turbines are likely to have a smaller impact on the environment compared to axial flow turbines due to their operation at lower tip speed ratios. Since very little experimental data is available presently for cross-flow turbines, this study provides an expansive set of performance data for two NACA series blade profiles of the same chord length. One blade profile was used in two different orientations …
