Comparison Of Horizontal Ground Source (Geothermal) Heat Pump Layouts For Optimal Performance And Thermal Efficiency, Elizabeth M. Bocchino
Comparison Of Horizontal Ground Source (Geothermal) Heat Pump Layouts For Optimal Performance And Thermal Efficiency, Elizabeth M. Bocchino
Honors Theses
This study investigates the difference in thermal efficiencies of horizontal ground source heat pump layouts through computer simulation and experimental modeling. The main objective of this project was to determine if the shape of the layout affects the total heat exchange in a horizontal geothermal system. Geothermal energy is power extracted from the Earth and studies have been focused on increasing the efficiency of the heat transfer from the Earth to the system. Steady state and transient thermal analyses were conducted on two horizontal layout shapes, a U-loop and a coil, in ANSYS Fluent. This system was not full size, …

New Catalysts For The Photocatalytic Reduction Of Carbon Dioxide To C1 Organic Compounds, Anna Hailey
Honors Theses
Photocatalytic reduction of carbon dioxide (CO2) has recently been identified as one of the five notable research areas in catalysis because it simultaneously reduces carbon emissions while storing clean, green solar energy in organic compounds. The development of efficient photocatalysts that take advantage of solar radiation is therefore an important area of research. Titanium dioxide (TiO2) is a commonly-used photocatalyst for this reaction, but it requires ultraviolet (UV) radiation to excite its electrons. Carbon-doping (C-doping) has been shown to reduce the intensity of energy required, thus allowing the photocatalyst to take advantage of the visible light spectrum. Copper (Cu), added …
Investigation Of Solid-State Shear Pulverization Processing Parameters For Polyethylene-Clay Nanocomposites , Ben Aldrich
Investigation Of Solid-State Shear Pulverization Processing Parameters For Polyethylene-Clay Nanocomposites , Ben Aldrich
Honors Theses
Investigates multiple processing parameters, includingpolymer type, filler type, processing technique, severity of SSSP (Solid-state shear pulverization)processing, and postprocessing, of SSSP. HDPE and LLDPE polymers with pristine clay and organo-clay samples are explored. Effects on crystallization, high-temperature behavior, mechanicalproperties, and gas barrier properties are examined. Thermal, mechanical, and morphological characterization is conducted to determine polymer/filler compatibility and superior processing methods for the polymer-clay nanocomposites.
