Optimization of staged rankine energy conversion cycles for high efficiency

Creator:: Simmons, Larry Dean
Abstract:: Because of the fuel crisis and problems associated with thermal pollution there is new impetus and urgency for developing more efficient energy conversion systems for power generation. A preliminary analysis was undertaken to determine the potential of staged Rankine cycle systems for substantially higher efficiency. It was necessary to optimize...

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...

Predicting Properties of Bio-jet Fuels using Machine Learning and ATR-FTIR Spectroscopy

Creator:: Mayer, Morgan A.
Abstract:: High-potential molecules derived from biomass sources may suitably replace or supplement traditional nonrenewable hydrocarbon fuels to reduce pollution and fuel processing costs. Due to expensive and time-consuming property testing, models that predict key properties from optical data would initially vet potential additives before investment and bench-scale testing. Attenuated Total Reflection...

Development and validation of acoustic measurement techniques for void fraction in concentric annular geometries

Creator:: Tost, Brian C.
Abstract:: This work investigates the acoustic velocity of gas-liquid mixtures in vertical, co-current flow in a concentric annulus. Acoustic velocity shows promise as a detection parameter for the presence and amount of gas in a liquid flow because of its high sensitivity to gas void fraction in a gas-liquid mixture. However,...

Response of guyed offshore towers to stochastic loads in the presence of steady current

Creator:: Brynjolfsson, Sigurdur
Abstract:: The validity of the widely used stochastic linearization method for analysing the response of guyed towers to stochastic loads is investigated. The governing equations of a guyed tower have two main sources of nonlinearities, fluid-structure interaction and the restoring force of the cables. In this study, two models are considered....

Part-Load Optimization of an Organic Rankine Cycle

Creator:: Ramsey, Owen
Abstract:: Waste-heat-recovery Organic Rankine Cycle (ORC) systems use excess heat from industrial processes to produce electrical power. In many cases, the temperatures and mass flow rates of these excess-heat streams vary significantly over time, causing the ORC to often operate far from its design point. In this study, a control strategy...

Transient fuel pin temperature calculations using describing functions

Creator:: Guidotti, Timothy E.
Abstract:: An important element in rector safety and fuel performance assessments is the efficient calculation of the time dependent temperature profiles within reactor fuel pins. Because the fuel pins have temperature dependent thermal properties, the governing partial differential equations are nonlinear. Traditionally, finite difference or finite element methods have been used...

Development of an emission sampling system for a mobile agricultural incinerator

Creator:: Hudson, Arthur E.
Abstract:: An emmission sampling system was developed to measure pollutants emitted from a mobile agricultural incinerator developed at Oregon State University. The system was designed to collect a particulate sample on an 8" x 10" fiber glass filter and collect a gaseous sample in a plastic bag. Pollutants measured were particulates...
