New technologies to valorize refuse-derived fuels (RDFs) will be required in the near future due to emerging trends of (1) the cement industry’s demands for high-quality alternative fuels and (2) the decreasing calorific value of the fuels derived from municipal solid waste (MSW) and currently used in cement/incineration plants. Low-temperature pyrolysis can increase the calorific value of processed material, leading to the production of value-added carbonized solid fuel (CSF). This dataset summarizes the key properties of MSW-derived CSF. Pyrolysis experiments were completed using eight types of organic waste and their two RDF mixtures. Organic waste represented common morphological ...

Large Scale Grid Integration Of Wind And Solar Power With Storage, Nicholas Moore
Macalester Journal of Physics and Astronomy
The current energy grid in the United States is dominated by carbon intense energy generation methods that are based on production when and where it is required. However, solar and wind power have proved themselves as the most promising carbon free energy generation sources. Due to the unpredictable and uncontrollable nature of energy production from solar and wind, large scale integration of these resources into the electric grid will require robust storage capacity. In this project, we model the energy grid of the Midcontinent Independent System Operator (MISO) energy region with high concentrations of solar and wind power to analyze ...

Investigation Of Infiltration Measurements Using Wind Induced Pressure Response On An Enclosure, Aaron R. French
Electronic Theses and Dissertations
Air infiltration into a building is unintentional air leakage, resulting in heat losses or gains and the consequent energy usage to recondition the building to comfortable levels. Methods of evaluating air infiltration provide accurate measures of air exchange rate but must be done per building and take significant experimentation and data collection. This warrants investigation into ways to decrease the time to evaluate building infiltration to decrease the associated costs. For this reason, interior pressure response is the subject of investigation in the present work. Interior pressure of a building responds to a pressure rise on the building face when ...

A History And Status Of Wind Energy Potential In Arkansas, Pre And Post Covid-19, Will Blasingame
Mechanical Engineering Undergraduate Honors Theses
Historically, wind-generated electricity has been the largest renewable energy sources in the United States. Wind-rich regions like Oklahoma and Texas have fueled growth and sold that electricity to electric utilities located in wind-poor states like Arkansas in the form of Power Purchase Agreements. Future technologies such as Vertical Axis Wind Turbines, small wind turbines, and Tesla turbines designed to generate electricity from wind show promise in unlocking more expensive wind resources in regions like Northwest Arkansas by mitigating concerns about low wind speeds and noise. However, more factors than just feasibility influence the growth of wind power. Governmental policies such ...

How the crystal structures of ordered transition-metal phosphide catalysts affect the hydrogen-evolution reaction (HER) is investigated by measuring the anisotropic catalytic activities of selected crystallographic facets on large (mm-sized) single crystals of iron-phosphide (FeP) and monoclinic nickel-diphosphide (m-NiP2). We find that different crystallographic facets exhibit distinct HER activities, in contrast to a commonly held assumption of severe surface restructuring during catalytic activity. Moreover, density-functional-theory-based computational studies show that the observed facet activity correlates well with the H-binding energy to P atoms on specific surface terminations. Direction dependent catalytic properties of two different phosphides with different transition metals, crystal structures, and ...

Basic Utilities Vehicle (Buv) Milk Transportation, Brian D. Reynolds, Sean Patrick Bayless Galligar, Emmitt Hanner, Joshua T. Pitts
Scholar Week 2016 - present
In developing countries, a need exists for the transportation of raw foods to communities without spoilage. Traditional methods of transporting goods don’t meet the needs of the consumer, and often times food is wasted due to the harsh climate and time constraints. Food often becomes salvage under the heat, causing a hurt to the profitability of vendors and family needs for fresh produce. In particular milk transportation has become difficult, due to the lack of cold storage in standard transit. As a response to the need for affordable raw food transport, our sponsor Basic Utilities Vehicle (BUV) has tasked ...

Ames Laboratory Accepted Manuscripts
In order to fully understand the lithium-ion transport mechanism in solid electrolytes for batteries, not only the periodic lattice but also the non-periodic features that disrupt the ideal periodicity must be comprehensively studied. At present only a limited number of non-periodic features such as point defects and grain boundaries are considered in mechanistic studies. Here, we discover an additional type of non-periodic feature that significantly influences ionic transport; this feature is termed a “single-atom-layer trap” (SALT). In a prototype solid electrolyte Li0.33La0.56TiO3, the single-atom-layer defects that form closed loops, i.e., SALTs, are found ubiquitous by atomic-resolution electron ...

Genetic algorithms (GAs) are considered to be one of the main types of evolutionary algorithms (EAs) and are being increasingly used in various engineering design applications. To a large extent, plate-fin heatsinks are used in the thermal management of compact electronic equipment and data centers. The shape optimization of the heatsinks is not rigorously investigated during the design process of high power electronics. Any improvements in the effectiveness of the heatsinks impact the energy consumed by large-scale information communication technology (ICT) facilities including data centers and telecommunication systems and promote a more sustainable use of raw materials. This paper investigates ...

This paper compared the thermal performance of two solar collectors. The first collector is coated by a dark black absorbent solar collector, and the second one coated by the chromium trioxide. The results of the second collector show a better selectivity in terms of greater radiation absorption, and less emission compared to the first collector. At the minimum solar irradiance time, the absorbed energy is increased from 908.28J to 1221.5J, and the thermal efficiency is improved from 37.3% to 50.1% when the chromium trioxide coating is used. Besides, at the maximum solar irradiance time, the absorbed ...

Solar energy is a renewable resource growing exponentially around the country over the past few decades. Solar energy works through the use of photo-voltaic cells, which work to convert energy from sunlight into electricity. This is done within solar panels, which are then connected to batteries for energy storage to use as needed. As production has increased over past decades, the cost for solar panel hardware and installment has thus fallen to meet consumer need. While most common implementations include solar panels attached to one’s home or solar panel ‘fields’ for charging entire towns, there has been a steady ...

Coarse-Grained Dynamically Accurate Simulations Of Ionic Liquids At Vacuum-Interface, Tyler D. Stoffel
Theses and Dissertations--Mechanical Engineering
Ionic liquids, possessing improved properties in many areas of technical application, are excellent candidates as components in development of next-generation technology, including ultra-high energy batteries. If they are thus applied, however, extensive interfacial analysis of any selected ionic configuration will likely be required. Molecular dynamics (MD) provides an advantageous route by which this may be accomplished, but can fall short in observing some phenomena only present at larger time/length scales than it can simulate. Often times this is approached by coarse-graining (CG), with which scope of simulation can be significantly increased. However, coarse-grained MD systems are generally known to ...

Isogeometric Analysis Of Ice Accretion On Wind Turbine Blades, Emily L. Johnson, Ming-Chen Hsu
Mechanical Engineering Publications
For wind turbines operating in cold weather conditions, ice accretion is an established issue that remains an obstacle in effective turbine operation. While the aerodynamic performance of wind turbine blades with ice accretion has received considerable research attention, few studies have investigated the structural impact of blade ice accretion. This work proposes an adaptable projection-based method to superimpose complex ice configurations onto a baseline structure. The proposed approach provides an efficient methodology to include ice accretion in the high fidelity isogeometric shell analysis of a realistic wind turbine blade. Linear vibration and nonlinear deflection analyses of the blade are performed ...
