Numerical Simulation Of Underground Solar Thermal Energy Storage, Marshall Sweet
Numerical Simulation Of Underground Solar Thermal Energy Storage, Marshall Sweet
Theses and Dissertations
The United States Department of Energy indicates that 97% of all homes in the US use fossil fuels either directly or indirectly for space heating. In 2005, space heating in residential homes was responsible for releasing approximately 502 million metric tons of carbon dioxide into the atmosphere. Meanwhile, the Sun provides the Earth with 1000 watts per square meter of power everyday. This document discusses the research of modeling a system that will capture and store solar energy during the summer for use during the following winter. Specifically, flat plate solar thermal collectors attached to the roof of a single …
Spatial Light Dilution As A Technique For Conversion Of Solar Energy To Algal Biomass, Daniel J. Dye
Spatial Light Dilution As A Technique For Conversion Of Solar Energy To Algal Biomass, Daniel J. Dye
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
A photobioreactor has been designed and developed to efficiently utilize solar irradiance through spatial dilution of sunlight. The concept of spatial light dilution is simple: incident sunlight is spread over a large surface area, thus reducing the photon flux density of the light. The implementation of this technique, however, is difficult. The reactor described within uses a new approach to spatial light dilution, utilizing recently-developed optical components to diffuse concentrated sunlight inside an algae culture. Preliminary productivity tests indicate a 2-3 fold increase in productivity per unit aperture (sunlight collection area) over a control reactor with direct-sunlight. Aperture productivity of …

Enhanced Cal Poly Super System Simulink Model, Matthew Ogden Mcfarland
Enhanced Cal Poly Super System Simulink Model, Matthew Ogden Mcfarland
Master's Theses
The Cal Poly Sustainable Power for Electrical Resources (SuPER) project is a solar power DC distribution system designed to autonomously manage and supply the energy needs of a single family off-the-grid home. The following thesis describes the improvement and re-design of a MATLAB Simulink model for the Cal Poly SuPER system. This model includes a photovoltaic (PV) array, a lead-acid gel battery with temperature effects, a wind turbine model, a re-designed DC-DC converter, a DC microgrid, and multiple loads. This thesis will also include several control algorithms such as a temperature controlled thermoelectric (T.E.) cooler, intelligent load switching, and an …
Simulation Of Cal Poly Super System Simulink Model Using Insolation Variation, Jacob Kory
Simulation Of Cal Poly Super System Simulink Model Using Insolation Variation, Jacob Kory
Electrical Engineering
This senior project focuses on simulation of the Cal Poly SuPER system using an insolation model. First, local and historical weather data is examined to determine the range of limits that the model will utilize. Then, the insolation model is constructed to fit into the existing SuPER model. The overall system is tested under a variety of insolation values to determine system performance of motor and static loads. Based on these simulations, several factors of the current model are discovered that limit the power consumption profile under off-peak load conditions. Finally, recommendations on improvements to the model are discussed

Synthesis And Characterization Of Metal Oxide Semiconductors For Photoelectrochemical Hydrogen Production, Sudhakar Shet
Synthesis And Characterization Of Metal Oxide Semiconductors For Photoelectrochemical Hydrogen Production, Sudhakar Shet
Dissertations
The goal of this thesis is to investigate the properties of metal-oxide thin films on fluorine-doped tin oxide (FTO)-coated glass substrates, prepared by using radio- frequency (RF) reactive magnetron sputtering for photoelectrochemical (PEC) applications. Metal-oxide thin films as a photoelectrode are of special interest for PEC systems to produce hydrogen in an aqueous solution by solar energy due to their low cost and potential stability.
The following list represents some of the accomplishments and results of this work:
- Narrowing of N-incorporated ZnO (ZnO:N) was achieved by reactive sputtering in a O2/N2 mixture ambient, and ZnO:N films with …

Solar-Powered Compaction Garbage Bins In Public Areas: A Preliminary Economic And Environmental Evaluation, Poppy Coleman, Long Nghiem
Solar-Powered Compaction Garbage Bins In Public Areas: A Preliminary Economic And Environmental Evaluation, Poppy Coleman, Long Nghiem
Faculty of Engineering - Papers (Archive)
An excel-based model was developed to evaluate economic and environmental benefits of the solar-powered compaction garbage bins in public areas in Australia. Input data were collected from Brisbane and Wollongong City councils, and Sydney Olympic Park. The results demonstrate that solar-powered compaction garbage bins would provide environmental benefits in all scenarios. However, results of the economic analysis of the three studied areas varied significantly. The unique situation of Sydney Olympic Park made implementation in that facility particularly appealing. A lower monthly rental cost is needed for the implementation of this novel waste management practice.

Feasibility Study Of Solar Driven Underground Cooling System, Michel E. Shafik
Durham School of Architectural Engineering and Construction: Dissertations, Thesis, and Student Research
In the United States the peak electrical use occurs during the summer. In addition, the building sector consumes a major portion of the annual electrical energy consumption. One of the main energy consuming components in the building sector is the Heating, Ventilation, and Air-Conditioning (HVAC) systems. This research studies the feasibility of implementing a solar driven underground cooling system that could contribute to reducing building cooling loads. The developed system consists of an Earth-to-Air Heat Exchanger (EAHE) coupled with a solar chimney that provides a natural cool draft to the test facility building at the Solar Energy Research Test Facility …
