Wing Flutter Suppression via Distributed Electric Propulsion

Creator:: Bamberger, Joshua
Abstract:: This research aims to demonstrate the viability of actively controlled distributed-electric propulsion as a method to postpone flutter in high aspect-ratio elastic wings. A semi-wing on a spring mount with two propellers powered by electric motors, mounted at alternate pitch angles relative to the chord line, was used as the...

Wind turbulence input model for horizontal axis wind turbines

Creator:: Lin, Shuh-ren
Abstract:: In order to estimate wind turbine residL2;characteristics in the presence of atmospheric turbulence, the important atmospheric sources for the force excitations felt by the wind turbine system must be identified and characterized. The goal of this research is to develop the wind turbulence input model for horizontal axis wind turbines....

Wind tunnel simulation and field measurements of flow over a coastal headland

Creator:: Brownlow, Roger West
Abstract:: An experimental study was made of the average and turbulent wind characteristics of the flow over a model of a coastal headland. The scale of the model was 300:1, corresponding to a prototype size of 500 m. The data for validation of the model study was obtained from instruments mounted...

Wave Energy From Idea, to Concept, to Converter: Structuring Methods for Design and Evaluation of Wave Energy Devices

Creator:: Trueworthy, Ali May
Abstract:: The amount of energy we use and the ways that we get that energy sit on the edge of dramatic change as the carbon budget which can keep the planet under 1.5C of global average temperature increase gets smaller (Allen, 2018). In response, we continue to research and develop renewable...

Wave Energy Converter Array Optimization : Array Economic Analysis and Preliminary Results of a Genetic Algorithm Approach Introducing Cost Factors

Creator:: Sharp, Christopher J.
Abstract:: With the need to integrate renewable energy sources into the current energy portfolio and the proximity of many population centers to an ocean coastline, it is pressing that marine energy systems, specifically wave energy converters (WECs), are evaluated as potential solutions for meeting energy needs. In order to best understand...

Wave Energy Converter Array Optimization : Algorithm Development and Investigation of Layout Design Influences

Creator:: Sharp, Christopher J.
Abstract:: Realizing the vast amount of energy available in ocean waves, an industry has emerged that is progressing towards the deployment of grid–connected wave energy converters. Likely to be deployed in arrays, a challenge to the wave energy industry is maximizing the energy production of such arrays. We have been developing...
