The wave energy resource of the US Pacific Northwest

Creator:: Lenee-Bluhm, Pukha
Abstract:: The substantial wave energy resource of the US Pacific Northwest (i.e. off the coasts of Washington, Oregon and N. California) is assessed and characterized. Archived spectral records from ten wave measurement buoys, operated and maintained by the National Data Buoy Center and the Coastal Data Information Program, form the basis...

Numerical and Analytical Modeling of Temperature Evolution in Laser Processing of Materials

Creator:: Ball, Stefan R.
Abstract:: The ultimate goal of this work is to analyze and compare two predictive models of thermal profile in laser processing of materials. An analytical method that uses closed-form equations to represent a geometric model of a laser heat source will be contrasted with a commercial computational fluid dynamics code that...

Predicting deep water breaking wave severity

Creator:: Hovland, Justin
Abstract:: Ocean Wave Energy Converters (WECs) operating on the water surface are subject to storms and other extreme events. In particular, high and steep waves, especially breaking waves, are likely the most dangerous to WECs. A method for quantifying the breaking severity of waves is presented and applied to wave data...

Development of a Cartesian-grid-based solver for an oscillatory boundary layer over a rough wall

Creator:: Skitka, Joseph M.
Abstract:: Predominant models for predicting rates of sediment transport face acute shortcomings when applied to coastal boundary layers. This is due to a neglect of the web of stochastic variables governing the rate of sediment dislodgement. While stochastic models do exist, the parametric extent of their validity tends to be limited,...

Computational Study of Smoldering Combustion in Cellulose and Hemicellulose Mixtures

Creator:: Mulky, Tejas Chandrashekhar
Abstract:: Due to global warming wildland fires are increasing in frequency and severity. In the case of wildland fires, the major modes of combustion occur include smoldering combustion and flaming combustion. Smoldering combustion occurs most commonly in porous fuels like peat, forest duff, and woody fuels, which are available in abundance...

Time-domain modeling of heaving point absorber wave energy converters, including power take-off and mooring

Creator:: Ruehl, Kelley
Abstract:: Wave energy conversion is still in its infancy, and in order for it to become a commercially viable technology, developers, investors and utilities need to estimate a Wave Energy Converter's (WEC's) performance for the wave climate of a potential installation site. With the goal of estimating a design's power output...

Experimental Validation of the Hydrodynamic Coefficients for an Oscillating Water Column Wave Energy Converter

Creator:: Bentivoglio, Marine M. J.
Abstract:: Resulting from the action of wind over open water surfaces, water waves contain colossal amounts of energy that has not yet been harnessed. Seen as a very promising source for renewable energy generation, many studies have tried to make wave energy a cost competitive source by investigating optimal designs of...

Hydroelastic modeling of a wave energy converter using the arbitrary Lagrangian-Eulerian finite element method in LS-DYNA

Creator:: Meicke, Stephen A.
Abstract:: This thesis investigates the applicability of the finite element method to model wave energy converter (WEC) hydroelasticity using LS-DYNA. The proposed methodology uses the Arbitrary Lagrangian-Eulerian formulation to model Fluid-Structure Interaction (FSI) between the WEC and the fluid elements. This formulation allows for time-domain modeling of higher order effects such...

Real-Time Estimation and Prediction of Wave Excitation Forces for Wave Energy Control Applications

Creator:: Ling, Bradley A.
Abstract:: Wave energy is emerging as a new potential source for renewable energy generation. However, wave energy technology is not currently cost competitive with other more mature renewable energy sources such as wind and solar. One approach that researchers and developers are taking to reduce the cost of wave energy is...

Design Optimization of a Structurally Flexible Wave Energy Converter with a Direct Search Algorithm

Creator:: Berrier, Austin S.
Abstract:: Several wave energy converter designs have been recently proposed that are made of flexible materials. Flexible devices are able to generate electricity by being stretched, and are intended to simplify deployment and maintenance concerns over existing wave energy devices. Due to the relative infancy of flexible wave energy converters, however,...
