Modeling, Design, Packaging And Experimental Analysis Of Liquid-Phase Shear-Horizontal Surface Acoustic Wave, Thomas B. Pollard
Modeling, Design, Packaging And Experimental Analysis Of Liquid-Phase Shear-Horizontal Surface Acoustic Wave, Thomas B. Pollard
Electronic Theses and Dissertations
Recent advances in microbiology, computational capabilities, and microelectromechanical-system fabrication techniques permit modeling, design, and fabrication of low-cost, miniature, sensitive and selective liquid-phase sensors and labon- a-chip systems. Such devices are expected to replace expensive, time-consuming, and bulky laboratory-based testing equipment. Potential applications for devices include: fluid characterization for material science and industry; chemical analysis in medicine and pharmacology; study of biological processes; food analysis; chemical kinetics analysis; and environmental monitoring. When combined with liquid-phase packaging, sensors based on surface-acoustic-wave (SAW) technology are considered strong candidates. For this reason such devices are focused on in this work; emphasis placed on device …
Design, Optimization, And Testing Of A Cross-Flow Tidal Turbine, Megan Colleen Swanger
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 …
Development Of A Scale Model Wind Turbine For Testing Of Offshore Floating Wind Turbine Systems, Heather Rae Martin
Development Of A Scale Model Wind Turbine For Testing Of Offshore Floating Wind Turbine Systems, Heather Rae Martin
Electronic Theses and Dissertations
This thesis presents the development of a 1/50th scale 5 MW wind turbine intended for wind and wave basin model testing of commercially viable floating wind turbine structures. The design is based on a popular 5 MW wind turbine designed by the National Renewable Energy Laboratory (NREL) commonly utilized in numerical modeling efforts. The model wind turbine is to accompany generic floating model platforms for basin model testing. The ultimate goal of the model development testing program is to collect data for validating various floating wind turbine simulation codes such as those developed by NREL. This thesis will present an …
