Facility Implementation, Production, And Use Of Biodiesel On A University Campus, Michelle Erin Rodio Apr 2012

Facility Implementation, Production, And Use Of Biodiesel On A University Campus, Michelle Erin Rodio

Doctoral Dissertations and Master's Theses

During the last two years, Embry-Riddle Aeronautical University has been in the process of having a fully-functional biodiesel processing facility on campus. Within this time, it was shown that biodiesel was a great alternative to diesel fuel based on emissions, performance, and cost, allowing for a grant of $10,000 being awarded to fund the project. Upon properly producing biodiesel, the fuel was tested in a John Deere 2653A tractor to see what differences, if any, existed when using a biodiesel blend over diesel fuel. In doing this, carbon buildup and fuel economy were compared, and a cost analysis conducted. It …


Sr2Fe1.5Mo0.5O6-Δ – Sm0.2Ce0.8O1.9 Composite Anodes For Intermediate-Temperature Solid Oxide Fuel Cells, Beibei He, Ling Zhao, Shuxiang Song, Tong Liu, Fanglin Chen, Changrong Xia Mar 2012

Sr2Fe1.5Mo0.5O6-Δ – Sm0.2Ce0.8O1.9 Composite Anodes For Intermediate-Temperature Solid Oxide Fuel Cells, Beibei He, Ling Zhao, Shuxiang Song, Tong Liu, Fanglin Chen, Changrong Xia

Faculty Publications

Sr2Fe1.5Mo0.5O6−δ (SFM) perovskite is carefully investigated as an anode material for solid oxide fuel cells with LaGaO3-based electrolytes. Its electronic conductivity under anodic atmosphere is measured with four-probe method while its ionic conductivity is determined with oxygen permeation measurement. Samaria doped ceria (SDC) is incorporated into SFM electrode to improve the anodic performance. A strong relation is observed between SDC addition and polarization losses, suggesting that the internal SFM-SDC contacts are active for H2 oxidation. The best electrode performance is achieved for the composite with 30 wt% SDC addition, resulting …


A Ceramic-Anode Supported Low Temperature Solid Oxide Fuel Cell, Hanping Ding, Junjie Ge, Xingjian Xue Mar 2012

A Ceramic-Anode Supported Low Temperature Solid Oxide Fuel Cell, Hanping Ding, Junjie Ge, Xingjian Xue

Faculty Publications

We report the fabrication and evaluation of a ceramic-anode supported button cell LSCM-SDC/SDC/PBSC (thickness 400 μm/20 μm/20 μm). The anode/electrolyte assembly LSCM-SDC/SDC was co-fired at low temperature of 1250°C, where a slight amount of CuO was mixed with LSCM. The CuO (20.3 wt%) were impregnated into the porous substrate to enhance current collecting effect. The cell exhibited power density of 596 mWcm−2 and 381 mWcm−2 at 700°C with wet hydrogen and methane as the fuel respectively, where the silver paste was used as current collectors, the highest performance up to date for the cells with metal oxide anodes at this …


Partnership For High Performance Housing Final Report, Florida Solar Energy Center, Janet Mcilvaine Mar 2012

Partnership For High Performance Housing Final Report, Florida Solar Energy Center, Janet Mcilvaine

FSEC Energy Research Center®

This report describes research conducted by the Florida Solar Energy Center (FSEC) under funding from the Pacific Northwest National Laboratory. This work falls under the umbrella of the U.S. Department of Energy's Building America program. High performance goals were set for renovation of existing housing and construction of new affordable housing. Both efforts included monitoring the energy use of several homes.


Creating Performance Curves For Variable Refrigerant Flow Heat Pumps In Energyplus, Florida Solar Energy Center, Richard Raustad Mar 2012

Creating Performance Curves For Variable Refrigerant Flow Heat Pumps In Energyplus, Florida Solar Energy Center, Richard Raustad

FSEC Energy Research Center®

This document describes methods to generate performance curve coefficients for variable refrigerant flow heat pumps in DOE's EnergyPlus building energy simulation program. Manufactures performance data for capacity and power are used to create full-load and part-load performance curves for cooling and heating operating modes. When performance variations for full-load capacity or power cannot be modeled using a single performance curve, the data set is divided into lower and upper temperature regions and dual performance curves are used. Table objects may also be created to substitute when performance curves do not provide the required accuracy. These performance curves or tables are …

Achieving Very High Efficiency And Net Zero Energy In An Existing Home In A Hot-Humid Climate: Long-Term Utility And Monitoring Data, Florida Solar Energy Center, Danny Parker Feb 2012

Achieving Very High Efficiency And Net Zero Energy In An Existing Home In A Hot-Humid Climate: Long-Term Utility And Monitoring Data, Florida Solar Energy Center, Danny Parker

FSEC Energy Research Center®

This study summarizes the first six months of detailed data collected about a single-family home that experienced a series of retrofits targeting reductions in energy use. The project was designed to develop data about how envelope modifications in heating, ventilation, and air conditioning and domestic hot water and renewable measures can result in considerable energy reductions and potentially net zero energy for an existing home. Using utility billing records and recent detailed monitoring data, this study was also able to chronicle the progress of energy reduction over a 22-year period.

A Simulation Analysis Of Photovoltaic Ac Module Integrated Converters In Parallel, Under Controlled Edge Shading Conditions, Lynette O'Callaghan, Mick Mckeever, Brian Norton Jan 2012

A Simulation Analysis Of Photovoltaic Ac Module Integrated Converters In Parallel, Under Controlled Edge Shading Conditions, Lynette O'Callaghan, Mick Mckeever, Brian Norton

Conference Papers

A DC and AC power simulation comparison of: a Photovoltaic (PV) array with a modular, parallel, AC converter configuration; and a series, string configuration with a central AC converter, is presented. The systems are simulated using a comprehensive range of edge shading scenarios and irradiance conditions. Power control and transformation circuitry must be designed for shade and module mismatch tolerance to prevent over-proportional power to shade losses, as average losses from Building Integrated PV (BIPV) systems are approximately 20 to 25%, due to shade, mismatch, differences in orientation and inclination, and temperature effects. 59.4% of the simulations showed gains in …


Numerical Simulation Of Natural Convection In Rectangular Enclosures Of Varying Aspect Ratios And Its Feasibility In Environmental Impact Management Studies, Charles R. Walker Jan 2012

Numerical Simulation Of Natural Convection In Rectangular Enclosures Of Varying Aspect Ratios And Its Feasibility In Environmental Impact Management Studies, Charles R. Walker

College of Graduate Studies: Theses & Dissertations

Author's abstract: Numerical simulation was used to investigate natural convection in horizontal and vertical enclosures with and without an internal heat source. Natural convection in rectangular enclosures is found in many real-world applications. Included in these applications are the energy efficient design of buildings, operation and safety of nuclear reactors, solar collector design, passive energy storage, heat transfer across multi-pane windows, thermo-electric refrigeration and heating devices, and the design-for-mitigation of optical distortion in large-scale laser systems. Considering all these applications, especially controlling heat transfer in nuclear power plants, knowledge and research results of natural convection in enclosure play a vital …
