Biaxial fatigue behavior of commercially pure titanium Ti-50A (Grade 2) and low-alloy titanium Ti-Code 12 (Grade 12) heat exchanger materials

Creator:: Tobias, Benjamin C.
Abstract:: Material failures in heat exchangers are often closely tied to events associated with the conditions of service and operating parameters. These events can generally be attributed to adverse load application and higher than optimum operating temperatures that could lead to changes in the microstructure of the materials and fatigue failure...

Energy resource conservation in new large power plants

Creator:: King, David C.
Abstract:: This thesis evaluates new, large power generating plants of the various types expected to be practicable in the time span of the next 50 years. By using thermodynamic principles, the plants are evaluated on the basis of conservation of energy; the basic assumption is that the best policy is the...

Effects of a thin, flexible nozzle on droplet formation and impingement

Creator:: Hawke, Shane R.
Abstract:: The droplet formation process in the vicinity of the nozzle exit and the behavior of a spreading droplet during impingement on a smooth glass surface were studied. Two nozzle geometries were tested. The first case was a stiff stainless steel nozzle plate 0.787 mm thick. The second case was a...

A study of laser generated Rayleigh and Lamb waves in graphite/epoxy composites

Creator:: Park, Heeyong
Abstract:: The application of laser generated ultrasonics was first demonstrated in the mid-seventies and has shown good potential when applied to isotropic materials. However, its use with composite materials is still in the early stages of development. This study explores the potential for application of laser generated Rayleigh and Lamb waves...

Operation of a High-Temperature Oxidation Reactor for Thermochemical Energy Storage

Creator:: Ramsey, Owen C.
Abstract:: The cost of long-duration energy storage poses one of the most significant limitations on the penetration of renewables into power grids. Thermochemical energy storage has great potential to reduce this cost through the use of a reversible redox reaction pair that has a high enthalpy of reaction. The chemical nature...

Fracture toughness of void-site-filled skutterudites

Creator:: Eilertsen, James S.
Abstract:: Thermoelectric materials are playing an increasingly significant role in the global effort to develop sustainable energy technologies. Consequently, the demand for materials with greater thermoelectric efficiency has stimulated the development of state-of-the-art interstitially doped skutterudite-based materials. However, since intermetallics are often embrittled by interstitial substitution, optimal skutterudite-based device design, manufacture,...

Automated Synthesis of Hybrid Energy Network Optimization using A* & Ensemble Forecasting

Creator:: Luc, Jonathan H.
Abstract:: This thesis describes a method for automatically generating and evaluating small-scale off-grid energy systems. Such systems are comprised of components such as solar panels, residential-scale wind turbines, batteries, inverters and charge controllers. These disparate components are assembled into feasible networks through the use of topological optimization and graph grammar rules....

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...
