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 …

Simulation And Analysis Of A Drilling Fluid Using A Herschel-Bulkley Model, Daniel Powell

Mechanical Engineering ETDs

In the study, a drilling fluid with known properties is analyzed and simulated in the laminar regime through a pipe with dimensions of 1.5m in length and 0.02m in diameter. The purpose of the conducted analysis is to demonstrate the advantages of the Herschel-Bulkley model currently used in the oil and gas industry for analyzing non-Newtonian drilling fluids.

For comparison, the analysis is also performed using more simple models for non-Newtonian fluids such as the Bingham Plastic model and the Power Law model and for a Newtonian fluid (water). In addition to analytical models, computations are conducted using …
