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 …

Physical Modeling Of The Atmospheric Boundary Layer In The University Of New Hampshire’S Flow Physics Facility, Stephanie Gilooly, Gregory Taylor-Power

Honors Theses and Capstones

The atmospheric boundary layer is the lowest part of the atmosphere, and is defined by a region from the surface of the earth to approximately 500-1000m altitude in which air velocity changes from zero at the surface to the velocity of the wind at a certain altitude. The type of atmospheric boundary layer is characterized by the terrain it encounters, varying from open sea and mud flats to suburban areas and city centers with high- and low-rise buildings. The goal of this project is to generate different types of atmospheric boundary layers for scale model testing in the UNH Flow …

Blds Articulated Mounting Feet, Mitchell D. Conn, Chris Mazzucco

Mechanical Engineering

This final report summarizes all of the efforts of the Senior Project aimed at creating Articulating Mounting Feet for the BLDS. The project focuses on improving the design of the mounting feet for the current Boundary Layer Data System at Cal Poly, San Luis Obispo. Dr. Russ Westphal, the project’s sponsor, wishes that our team focus primarily on a reliable and lightweight mount design for a curved wing, with only transverse curvature. Dr. Westphal is currently researching the boundary layer effects on airplane wings at Cal Poly, and the ability to mount to a multitude of surface contours would increase …
