Molecular Mechanisms And Design Of Hydrogen-Bonded Materials For Thermal Applications, Jinlong He
Molecular Mechanisms And Design Of Hydrogen-Bonded Materials For Thermal Applications, Jinlong He
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Heat transfer at the nanoscale plays an important role in determining the reliability and performance of many innovative advanced materials technologies such as nanoelectronics, semiconductor, biomedical devices, polymers, and composites. Extensive efforts have been made to design materials with extraordinary thermal properties. However, fundamental understanding of heat transfer in many of these materials is still not lacking, because the thermal transport processes are governed by several factors including molecular morphology and chemical bonding. Among these factors, the atomic bonding between two dissimilar materials or within single materials is of particular interest due to its ubiquity and importance in physical processes. …

Coin Recovery Ii, Carly Lofthouse
Undergraduate Honors Capstone Projects
Western Metals Recycling (WMR), a subsidiary of NUCOR Steel, is a metals recycling company with a location in Plymouth, Utah. At Plymouth, a 50 NT/hr. non-ferrous recovery plant uses eddy current technology to generate a non-ferrous product called zorba. Zorba is a mix of aluminum, copper, brass, zinc, printed circuit boards, coins, lead, and the like. (Figure 1) The market value of zorba varies but generally ranges from $0.30 to $0.50 per pound. The value of the coins (not including pennies) is much higher than zorba price. The team's objective is to upgrade and optimize the existing trommel equipment to …
Thermal Modeling And Analysis Of Roadway Embedded Wireless Power Transfer Modules, Arden N. Barnes
Thermal Modeling And Analysis Of Roadway Embedded Wireless Power Transfer Modules, Arden N. Barnes
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Wireless charging of electric vehicles is a developing technology which potentially increases efficiency and safety. It also allows for charging vehicles while they are moving by having charging stations embedded in the roadway. Because roadways are thermally insulating, it is important to know how the heat from the charging stations will move through the roadway, which will allow further research into whether the heat will cause damage to the components in the station or to the roadway. This thesis studies the way the heat moves through concrete with wireless charging coils embedded in it. This is accomplished by measuring the …
Optimization Of Aileron Spanwise Size And Shape To Minimize Induced Drag In Roll With Correlating Adverse Yaw, Joshua R. Brincklow
Optimization Of Aileron Spanwise Size And Shape To Minimize Induced Drag In Roll With Correlating Adverse Yaw, Joshua R. Brincklow
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Most modern aircraft make use of modifying the main wing in flight to begin a roll. In many cases, this is done with a discrete control surface known as an aileron. The lift, drag, and moments for the wing are affected in part by the location and size of the ailerons along the length of the wing. The lift, drag, and moments can be found using a lifting-line theory that considers the circulation in airflow from many small sections of the wing. To minimize the drag due to lift on the wing, the ailerons must be optimized for the best …
Transient Thermal Modeling Of Bioprocessing Equipment, Cody M. Cummings
Transient Thermal Modeling Of Bioprocessing Equipment, Cody M. Cummings
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Bioprocessing is leveraging cells to produce high value, lifesaving products. Precise environmental control is needed to maintain integrity of the bioprocessing production process. Temperature control requires both appropriate equipment choice and correct control parameter selection. To aid in the equipment selection process, enable better understanding of equipment capacity, and enable optimization of control parameters, a transient thermal model of both heat transfer characteristics and control systems was created in silico.
Benchmarking Of A Mobile Phone Particle Image Velocimetry System, David Armijo
Benchmarking Of A Mobile Phone Particle Image Velocimetry System, David Armijo
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
One of the most important tools in a fluid dynamics laboratory is a particle image velocimetry (PIV) system. This system can measure the speed of a fluid flow simply by taking high-speed images of the motion of the fluid, then applying PIV cross-correlation software to calculate speed from the resulting images. The mI-PIV project is in the process of designing a new method of performing PIV by putting the cross-correlation software on a mobile phone application, called mobile Instructional PIV (mI-PIV). This system is an innovative stepping stone in making PIV systems more widely available. It is designed to be …
Fluted Films Caused By Gravity Driven Water Drainage From Vertical Tubes, Matthew B. Jones
Fluted Films Caused By Gravity Driven Water Drainage From Vertical Tubes, Matthew B. Jones
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
When a stationary mass of water in a vertical tube is suddenly released, it creates a variety of artistic shapes and behaviors as it escapes the tube exit. As the descending water accelerates in the tube, friction along the tube wall slows the outer radius, resulting in a moving film entrained on the tube that trails the main body of water. When this film exits the tube, surface tension, gravity, and inertia interact to cause the film to create a wide variety of shapes, including jets, tubes, water bells, champagne glasses, and bubbles; rich forms that appear in other natural …
Pitched Baseballs And The Seam Shifted Wake, Andrew W. Smith
Pitched Baseballs And The Seam Shifted Wake, Andrew W. Smith
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
An experiment was conducted to investigate the effect that seams have on the way a baseball moves through the air. An examination of the airflow around a baseball led to the understanding that when seams are in certain areas on the baseball's surface the airflow changes. A subsequent experiment was performed which showed that when these changes in airflow were on one side of the baseball more than the other, the ball moved away from the side with the seams. This movement is in a different direction than the movement direction caused by a ball's spin. These experiments were done …

Flash Lab: A High-Speed Imaging Laboratory, Cody D. Hatch
All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
To help students become better acquainted with high-speed instrumentation and measurement techniques, a high-speed imaging laboratory for the College of Engineering is equipped with a high-speed camera and schlieren imaging device. The laboratory will be used for labs in classes, such as Instrumentation, Thermal/Fluids Lab, Experimental Solids, and Mechanical Experiments. In addition, graduate students will use it for research purposes. The laboratory also has the potential to have a course associated with it that would include the image processing techniques for a variety of applications (e.g., a course on high-speed imaging). The scope of this project will be to create …
Improvement Of Ultraviolet Digital Image Correlation (Uv-Dic) At Extreme Temperatures, Thinh Quang Thai
Improvement Of Ultraviolet Digital Image Correlation (Uv-Dic) At Extreme Temperatures, Thinh Quang Thai
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Extreme temperature has increasingly played an essential role in design and operation of various engineering applications including spacecraft re-entry, hypersonic flight, next-generation nuclear reactors, and hot-fire rocket testing. To protect instruments against the harsh environments, it is preferable to use non-contacting measurements when monitoring the integrity of those mechanical structures. Digital Image Correlation (DIC) is a popular method which uses digital cameras in order to track motion thanks to images acquired before and after deformation. Displacements and strains are plotted over a full-field region which is conducive to identify highly risky zones. At high temperature, objects emit light which interferes …
