An Experimental Study On Drag Reduction Of Aftermarket Additions On An Suv, Christiana L. Katsoulos
An Experimental Study On Drag Reduction Of Aftermarket Additions On An Suv, Christiana L. Katsoulos
Senior Honors Projects, 2010-2019
Over recent years, the awareness of climate change has become more prevalent worldwide and one major contributor to global warming has been the use of transportation. Vehicles contribute to global warming by releasing petroleum based emissions such as significant amounts of carbon dioxide and numerous other harmful environmental pollutants. SUVs contribute to the emissions problem more so than sedans, since they have lower gas mileage and need more gasoline regularly. The main functionality of sport utility vehicles, or SUVs, includes hauling or off-roading and fuel efficiency is not always the focus in the design process. However, aerodynamic enhancements could improve …
Process Development And Implementation For The Imaging Of Heat Treated A2 Steel For Consolidation Into An Atlas, Jessica Roberts
Process Development And Implementation For The Imaging Of Heat Treated A2 Steel For Consolidation Into An Atlas, Jessica Roberts
Senior Honors Projects, 2010-2019
Material processes, properties, and microstructure are interconnected, often visualized as the points of a triangle. Changing the process a material goes through will in turn change the properties and microstructure of that material. In materials research and education (specifically with metals), comparison between research or experiment results and scholarly-accepted results is important. When reading textbooks addressing different properties of metals and the process of metal treatment, images are often shown of the various microstructures associated with each property or process stage. The difficulty comes in trying to compare the stages or properties to one another; often different materials and processes …
Life Cycle Sustainability Analysis (Lcsa) Of Polymer-Based Piping For Plumbing Applications, Andy J. Rivas Bolivar
Life Cycle Sustainability Analysis (Lcsa) Of Polymer-Based Piping For Plumbing Applications, Andy J. Rivas Bolivar
Senior Honors Projects, 2010-2019
Water conveyance systems play a critical role in modern developed areas. Polymer pipes have been used for about a century, and their convenient physical properties have positioned polymers as the leading material in the piping industry. Having such influence in the market means that changes in current material selection and manufacturing could lead to significant reductions in the footprint associated with their products. Currently, there are no comparative lifecycle assessments that evaluate the different polymer selections commercially available, which makes it hard to determine what products have the least impact on the environment. Understanding how such impacts are relative to …

Over the last 40 years, the average new United States house has increased in size by more than 1,000 square feet, from an average size of 1,660 square feet in 1973 (earliest year available from the Census Bureau) to 2,687 square feet last year (Perry, 2016). In that same time period, there was a 91% increase in home square footage per inhabitant and a decrease in average household size. According to the U.S. Census Bureau, the average home in the United States costs approximately $358,000 to build, an increase of roughly $200,000 since 1998. Meanwhile, the average annual income in …
Experimental Analysis Of R134a, R22, And R404 For An Edibon Taab: Air Conditioning Lab Unit, Kyle T. Heesen
Experimental Analysis Of R134a, R22, And R404 For An Edibon Taab: Air Conditioning Lab Unit, Kyle T. Heesen
Senior Honors Projects, 2010-2019
This paper presents an experimental analysis of an Ebidon® TAABTM: Air Conditioning Lab unit running on R-134a being compared with R22 and R404 refrigerants, a $24,449 piece of equipment purchased by the JMU ISAT Department. In this paper we will compare the performance of the R-134a refrigerant under a range of working conditions and compare them to how the system would run on R22 or R404. The experimental tests use varying fan speeds and the R-134a data collected is compared to simulated data collected for R22 and R404. Analysis of the collected data and simulated data will be compared on …
