Design Of A Test Frame And Its Corresponding Test Methods For A Deployable Composite Boom, William Luther Montgomery
Design Of A Test Frame And Its Corresponding Test Methods For A Deployable Composite Boom, William Luther Montgomery
Theses and Dissertations
Deployable composite booms (DCB) are an advanced class of support beams growing in applications including solar collectors and solar sails. DCBs can be coiled or folded into a compact footprint and the ability to be deployed, and in some design, concepts redeployed, making them optimal components for aerospace where weight and volume are finite resources. DCBs are a cutting-edge technology that has yet to be perfected with a need for longer booms with increased stiffnesses to accommodate the latest proposed designs. Atomic-6 has proposed a 16-foot boom manufactured using an autoclave process which aims to reach the goal of producing …
A Screening Tool For The Implementation Of Electric And Thermal Energy Storage Systems At Commercial And Industrial Facilities, Mckenna P. Amerson
A Screening Tool For The Implementation Of Electric And Thermal Energy Storage Systems At Commercial And Industrial Facilities, Mckenna P. Amerson
Theses and Dissertations
The integration of on-site renewable systems with energy storage devices is an important topic in improving energy management for commercial buildings and industrial facilities. Energy storage technologies have the ability to impact the end user’s power reliability while creating measurable energy and cost savings. However, the potential yet remains to increase the application of these systems. To determine the feasibility of renewables and energy storage in commercial and industrial applications, a pre-screening software tool is developed using data-driven algorithms to complete an energy, cost, and carbon savings analysis of storage implementation. A case study of a standalone retail building is …
Investigating Solutions For Peak Electrical Demand In Central Region, Saudi Arabia, Abdulhameed Mohammed Almaarik
Investigating Solutions For Peak Electrical Demand In Central Region, Saudi Arabia, Abdulhameed Mohammed Almaarik
Theses and Dissertations
This thesis studies the electrical power challenges of the Central Region, Saudi Arabia. This includes a look into the geography of Saudi Arabia, to assess the lack of traditional power sources such as coal and hydroelectric. Next, a comprehensive look into the nature of demand in Riyadh, which include the demand types, and comprehensive data about the peak demand and the times associated with it. A problem of very high peak demand that is unique to the region is identified. Then, a study into current electric generation methods to meet this demand, and the associated technologies and fuel costs. This …
Water Soluble Polymer Solar Cells From Electrospray Deposition, Marshall Sweet
Water Soluble Polymer Solar Cells From Electrospray Deposition, Marshall Sweet
Theses and Dissertations
This dissertation reports the fabrication and characterization of thin films from the water soluble polymer sodium poly[2-(3-thienyl)-ethyloxy-4-butylsulfonate] (PTEBS) by electrospray deposition (ESD). Contiguous thin films were created by adjusting the parameters of the electrospray apparatus and solution properties to maintain a steady Taylor cone for uniform nanoparticle aerosolization and controlling the particle water content to enable coalescence with previously deposited particles. The majority of deposited particles had diameters less than 52 nm. A thin film of 64.7 nm with a root mean square surface roughness of 20.2 nm was achieved after 40 minutes of ESD. Hybrid Solar Cells (HSCs) with …
Modeling Of Complex Pentahedron Solar Still Covers To Optimize Distillate, Jeremy D. Lefevre
Modeling Of Complex Pentahedron Solar Still Covers To Optimize Distillate, Jeremy D. Lefevre
Theses and Dissertations
This work shows the results of modeling and optimizing pentahedron-shaped covers for application on a passive solar still. While modeling under the assumption of clear weather in Provo, Utah, United States of America, it was found that two main geometries resulted: A single slope still with fully vertical back and sidewalls and a south face tilted at 37.1°, absorbing a total of 8.98 megajoules of direct solar radiation. A half-pyramid shaped cover with vertical backwall, sidewalls tilted in at 60.6°, and a south face tilted in at 41.5°, absorbing 9.34 megajoules of direct solar radiation.With improved covers, solar radiation absorbed …
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 …
