Modeling hop kilning with respect to energy consumption and drying kinetics

Creator:: Thomas, Matthew W.
Abstract:: Currently, little work has been performed studying energy consumption in hop kilning. This thesis explores drying with an alternative drying schedule that extends the initially elevated drying temperature currently used by growers and examines its impact on drying time and energy use. Extending the time of the initially elevated drying...

The Feasibility of Process Intensification of the Water-Gas Shift Reaction using Differential Temperature Microreactors

Creator:: Tolley, Thomas E.
Abstract:: Hydrogen is an increasingly attractive low-carbon energy carrier for a variety of stationary and mobile applications. Currently, the vast majority of hydrogen in the United States is produced via the energy intensive steam reforming of natural gas. The cost and carbon emissions associated with hydrogen production can be reduced by...

Sensitivity of Hashin damage parameters for notched composite panels in tension and out-of-plane bending

Creator:: Wright, Thomas J.
Abstract:: When using Finite Element Analysis (FEA) to model notched composite panels, the values of certain material properties can have a great effect on the outcome of the simulation. Progressive damage modeling is used to model how a composite structure will fail, and how that failure will affect the response of...

Characterizing Linkages Between the Climate, Cryosphere, and Impacts on Run-of-River Hydropower in Data-Sparse Mountain Environments

Creator:: Mosier, Thomas M.
Abstract:: In many regions of the world, a significant portion of the surface water originates in mountain headwaters where the timing and magnitude of streamflow is largely dictated by the seasonal storage of precipitation as snowpack and long-term storage as glaciers. Accumulation, persistence, and melt of snow and ice are functions...

Design, modeling and performance of miniature reciprocating expander for a heat actuated heat pump

Creator:: Herron, Thomas G.
Abstract:: A miniature reciprocating expander is being developed as part of a larger program to develop a heat actuated heat pump for portable applications. By utilizing the higher energy density of liquid hydrocarbon fuels relative to batteries, a heat actuated heat pump would be able to provide cooling for much longer...

Evaluating Stiffness Metrics for Predicting the Cost of Chemical Kinetics Integration

Creator:: Alferman, Andrew Thomas
Abstract:: Simulations of combustion and reacting flows often encounter stiffness in the equations governing chemical kinetics. Explicit solvers for these ordinary differential equations offer low computational expense, but typically cannot efficiently handle stiff systems. In contrast, implicit methods demand greater expense but offer unconditional stability—as a result, most reactive-flow solvers rely...

Micro-bubble dynamics in two-phase flow through a micro-channel

Creator:: Shepard, Thomas G.
Abstract:: An experimental investigation into the behavior of micro-bubbles flowing through a micro-channel has been conducted. Experiments were performed within a rectangular micro-channel with dimensions of 5 cm x 13.2 mm x l30 jim. Bubbles were generated in an electrolyte solution by electrolysis at the lower channel wall near the inlet....

Automating aquatic insect identification through pattern recognition

Creator:: Thomas, Joshua K.
Abstract:: Aquatic insect population counts can be a good indicator of the health, or water quality, of rivers and streams. Stoneflies (Plecoptera) are particularly susceptible to pollution in streams. However, today’s current method for obtaining these population counts requires biologists to examine individual specimens under a microscope for identification to the...

Automated Tradeoff Analysis of Cost Versus Machinability for Design Feedback

Creator:: Grier, Alan Thomas
Abstract:: As CAD tools become more sophisticated, engineers are able to more easily create complex part geometries with minimal mass given strength and stiffness requirements. However, these complex part geometries can be difficult to subtractively manufacture, which consequently increases manufacturing cost and production time. This thesis presents a method independent of...

Experimental Characterization of a Supercritical Carbon Dioxide Microchannel Solar Thermal Receiver

Creator:: L'Estrange, Thomas
Abstract:: Characterization of a microchannel solar thermal receiver for supercritical carbon dioxide (sCO₂) is presented. The receiver design is based on conjugate computational fluid dynamics and heat transfer simulations as well as thermo-mechanical stress analysis. Two lab scale receivers with a 2x2 cm² absorber area are fabricated and experimentally characterized -...
