Concentrated solar power (CSP) is a reliable renewable energy source that is progressively lowering its cost of energy. However, the heat loss due to reflected and emitted radiation hinders the maximum achievable thermal efficiency for solar receiver tubes on the solar tower. Current solar selective coatings cannot withstand the high temperatures that come with state-of-the-art CSP towers often needing to be recoated soon after initial operation. We intend to use Inconel 718 with different additive manufacturing (AM) practices to construct surfaces that allow for more light-trapping to occur. By adjusting printing parameters, we can tailor a surface to allow for …

Industrial and Manufacturing Engineering
RecorDIY is an affordable alternative to ordering Vinyl Records from a manufacturer in the form of an at-home record-cutting lathe. This report will cover the record cutting process from audio to physical, at home record lathes that are currently available, and the possible improvements that I plan to implement in order to make these devices a more viable alternative for small artists. Current models can only create low fidelity records, specifically they struggle with lots of “noise”, extra sounds such as static that make it harder to hear the actual audio. Another issue is record size, as current models can …

Laser-induced-forward-transfer (LIFT) bioprinting technology has been viewed as a regenerative medicine technology because of its high printing quality and good cell viability. To stabilize the jet to achieve high-quality printing, an energy-absorbing layer (EAL) can be introduced. In this study, three materials (graphene, gelatin, and gold) were utilized as the EAL. The effect of each EAL on the jet generation process was investigated. Besides, the effect of graphene EAL thickness was addressed for various experimental conditions. The jet generation process using sodium alginate solutions with different concentrations (1 and 2 wt. %) was also discussed to investigate the effect of …

Naphtha is an important distillation product of crude oil, and is used as a raw material for first-generation products such as ethylene, propylene, gasoline, xylene (BTX), and others. However, due to the different sources of crude oil, differences in naphtha composition impact the quality of conversion processes. Parameters such as pressure, charge flow, and temperature need to be adjusted for conversion efficiency. This work aims to compare naphtha samples from different origins, through the analysis of distillation curve (ASTM D86), density (ASTM D4052), total sulfur (ASTM D4294), and n-paraffins, iso-paraffins, olefins, naphthene, and aromatics (PIONA, ASTM D5134). Among these parameters …

Laser induced forward transfer (LIFT) bioprinting has been viewed as a new and actively developed three-dimensional bioprinting technology due to its high accuracy and good cell viability. The printing quality is highly dependent on the jet formation and its stability in the LIFT bioprinting process. The objective of this study is to investigate the effect of a graphene Energy Absorbing Layer (EAL) and alginate hydrogel (SA) (w.t. 1% and 2%) viscosity on jet generation in the LIFT bioprinting process. Since SA exhibits a shear-thinning behavior, it is a non-Newtonian fluid. The effect of EAL thickness and SA’s viscosity were addressed …

Graduate Theses, Dissertations, and Problem Reports
Manufacturing is a promising technique for producing complex and custom-made parts with a high degree of precision. It can also provide us with desired materials and products with specified properties. To achieve that, it is crucial to find out the optimum point of process parameters that have a significant impact on the properties and quality of the final product. Unfortunately, optimizing these parameters can be challenging due to the complex and nonlinear nature of the underlying process, which becomes more complicated when there are conflicting objectives, sometimes with multiple goals. Furthermore, experiments are usually costly, time-consuming, and require expensive materials, …

Williams Honors College, Honors Research Projects
This research project will be completed with Hendrickson Trailer as the sponsor. The goal of the project is to create a lift kit for a newer suspension system. The lift kit must provide enough lift force to lift an axle off the road and suspend it off the road while in transit. There are similar systems offered for different products at Hendrickson, but the configuration of this system is such that new brackets must be designed. The benefit of such a system is a reduction in wear on the lifted tires, and thus an increase in the life of the …

Williams Honors College, Honors Research Projects
The goal of this project was to design three different models of a coaxial beam eAxle for a range of electric vehicles. The requirement was to satisfy three different loading conditions, each characterized by a GAWR. These three loading conditions were 3000lb, 7500lb, and 10,000lb. This was done by first creating a model based on a basic outline given by Schaeffler. This model was then analyzed using Ansys®, and then iterated upon by designing new models using the 3D design program Solidworks. The iteration process was continued using more Ansys® analysis, as well as calculations to determine things like bolt …
