Integration Of Process Parameter Control And Digital Image Correlation Methods In An Investigation Of The Variability Of Marine Polymer Matrix Composite Material Properties, Keith Andrew Berube
Integration Of Process Parameter Control And Digital Image Correlation Methods In An Investigation Of The Variability Of Marine Polymer Matrix Composite Material Properties, Keith Andrew Berube
Electronic Theses and Dissertations
The very nature of continuous fiber composite materials, with their heterogeneous structure of layered and interwoven fibers bound together by a polymer resin matrix, lead to an inevitable variability in mechanical properties. This is especially true if the fabrication process is not well controlled. Unlike fabricating components with metals, where the properties of the material are known beforehand, the final properties of the composite material are determined during the process of fabricating the composite part. The research described herein was undertaken to better enable the use of polymer matrix composites in the marine construction industry by developing a knowledge base …
Flow Field Measurements For A Cross Flow Turbine, Matthew Cameron
Flow Field Measurements For A Cross Flow Turbine, Matthew Cameron
Electronic Theses and Dissertations
Understanding the flow pattern around hydrokinetic devices is important for the development of tidal energy technology. The objective of the research is to provide the wake characteristics from laboratory measurements, including wake structure, and flow recovery in the near and far fields of a cross-flow turbine. The data can be used to assist in optimization of an array of turbines by providing experimental results for numerical models validation and industrial developers of tidal energy. Another critical use of this data will be to provide a basis for parameterization of energy extraction in coastal ocean models in resource assessment. The experimental …
Testing Of A Ducted Axial Flow Tidal Turbine, Thomas A. Lokocz
Testing Of A Ducted Axial Flow Tidal Turbine, Thomas A. Lokocz
Electronic Theses and Dissertations
Energy independence and a reduction on the reliance on fossil fuels is a critical area of current research and development. Utilizing the energy in the world’s oceans can help the world move towards a more sustainable energy supply. One of the most promising sources of ocean energy is tidal energy or marine hydrokinetics, the topic of this thesis. This research analyzes the performance of a ducted axial flow tidal turbine and compares the result to an unducted turbine. While the focus of this research is on experimental results obtained in tow tank tests, the turbine and duct were designed using …
