Methodology for evaluating mechanical power in small-scale WEC experiments

Creator:: Simmons, Asher
Abstract:: Wave energy converters (WECs) are a broad class of emerging technology that converts hydrokinetic energy into some other useful form, such as electricity. The last stage in this transformation, the power take-off (PTO) subsystem, is often not experimentally evaluated until half-way through the recommended development process. This delay in evaluation...

Risk- and Reliability-Based Design Optimization in Offshore Renewable Energy Systems

Creator:: Clark, Caitlyn E.
Abstract:: Offshore wind and wave energy have the potential to be significant sources of future global electricity production, reduce carbon emissions, decrease dependence on energy importation, and stimulate economic growth in coastal and remote areas. Fixed-foundation and floating offshore wind and wave energy technologies are at different stages of development, but...

Extreme Wave Runup and Runup Variability on Beaches

Creator:: Li, Chuan
Abstract:: Wave runup is an important physical process that affects nearshore sediment transport, coastal erosion, and flooding. Large and unexpected runup events can also be dangerous to beach goers. Extreme runup statistics are essential parameters used in engineering design of marine structures and in coastal management. Although the study of runup...

Coupled Eulerian-Lagrangian Finite Element Modeling Approach Applied to Wave Structure Interaction: Effects of Shielding, Channeling, and Wall Removal

Creator:: Al-Sayhood, Zeyad A.
Abstract:: The impact of tsunamis on coastal structures gained great a new impetus following the 2004 Indian Ocean Tsunami and the 2011 Tohoku earthquake and tsunami. While several experimental programs have been performed to gain a fundamental understanding, numerical models are needed to study additional features that cannot all be tested...

Probabilistic Multi-hazard Earthquake-Tsunami Structural Risk Assessment Framework

Creator:: Alam, Mohammad Shafiqual
Abstract:: Catastrophic earthquake and tsunami events that resulted in significant loss of life and property over the past two decades have raised the global awareness regarding the need to understand the response of communities and their built environment to multi-hazard extreme events. In recognition to this impending threat to the coastal...

Global Hierarchical Control of a Park of Spar Buoy-type Floating Oscillating Water Column Wave Energy Converters

Creator:: Gaebele, Daniel T.
Abstract:: Converting energy from ocean waves is a challenging area for control theory application because of the nonlinear dynamics in various time scales. Generally, wave energy converter (WEC) control is applied in order to maximize power absorption, in the most common wave conditions, and subject to the devices’ physical constraints. Commonly,...

Engineering Services of Submerged Aquatic Vegetation (SAV): Investigation of the Land-Building and Energy-Attenuating Properties of SAV Habitats Across Spatial Scales

Creator:: Holzenthal, Elizabeth R.
Abstract:: Submerged aquatic vegetation (SAV) species, such as seagrasses, are highly valued in estuaries because of the many economic, ecological, and cultural services that they provide, including shelter for fisheries, minimizing water turbidity, and improving am-bient water quality. SAV can also alter its physical environment by attenuating wave and current velocities,...

Development and Analysis of Higher-order Nonlinear Wavemaker Theory for Intermediate to Deep-water Waves Based on Inverse Scattering Transform

Creator:: Mohtat, Ali
Abstract:: The modeling and analysis of laboratory-generated nonlinear intermediate- to deep-water wave fields, using existing wavemaker theories and analysis tools, is one of the most challenging tasks in ocean science and engineering. On one hand, harmonics function (sine and cosine) -based wavemaker theories result in an inherent (linear) instability of the...

Tsunami Loading on Coastal Infrastructure

Creator:: Xie, Zhongliang
Abstract:: The safety of coastal infrastructure has been a concern after the Indian Ocean Tsunami in 2004 and the Great East Japan Tsunami in 2011. The western coast of the United States is also exposed to tsunami hazards due to the Cascadia subduction zone. Therefore, it is critical to design coastal...
