Condensation of a zeotropic mixture, R-454C, and its individual components, R-1234yf and R-32, in microfin tubes

Creator:: Matty, Ethan P.
Abstract:: This work compares the condensation heat transfer and pressure drop for zeotropic refrigerant R-454C and its individual components, R-32 and R-1234yf, in horizontal microfin tubes. One microfin tube has a 4 mm outer diameter, 0.18 mm wall thickness, and a surface area ratio of 1.56. The second tube has a...

Evaluation of Adoptability : The Iterative Development of an Energy Production Device for the Middle School Classroom

Creator:: Heck, Samuel T.
Abstract:: This study conducts follow up research to my Mechanical Engineering Senior Project that was completed in March 2015. It follows the Student Powered Hydro and Entertainment Device (SPHED) as it is used in various middle school and high school classrooms. SPHED has three modules: a power generation module, a hydropower...

Detecting fluid flows with bioinspired hair sensors

Creator:: Dickinson, Benjamin T.
Abstract:: Many animals detect prey or enhance their locomotion with information from hair-like receptors that are activated by local fluid flows. The utility of biological hair receptors has motivated the design of artificial hair sensors (AHS) for flow control applications where aerodynamic or hydrodynamic forces play a significant role in the...

Turning Brake Cylinder Housing

Creator:: Radcliffe, Noah
Abstract:: The purpose of this project is to assist the OSU Baja Racing vehicle in turning more sharply. This is done using a turning brake, which locks one rear wheel to facilitate turning on a smaller radius. This project focuses on the development of a custom cylinder housing for the turning...

Experimental investigation of supercritical heat transfer of carbon dioxide in parallel square microchannels with a single-wall constant heat flux boundary condition

Creator:: Zada, Kyle R.
Abstract:: In the vicinity of the pseudocritical point, supercritical carbon dioxide (sCO₂) undergoes a steep change in properties from “liquid-like” to “gas-like” as it is heated at a constant pressure. At the same time, there is a large spike in specific heat which can yield high heat transfer coefficients and heat...

Automated decomposition of complex parts for manufacturing with advanced joining processes

Creator:: Massoni, Brandon R.
Abstract:: Recent advancements in joining operations and additive manufacturing now allow complex metal parts to be built up from raw materials, as opposed to being machined down from solid blocks. This not only opens up the design space, but also allows for much more efficient manufacturing. By decomposing a complex part...

Sustainable building design framework : an integrated approach

Creator:: Piacenza, Joseph R.
Abstract:: This paper combines two research publications working toward the development of an integrated framework for commercial sustainable building design. Current methodologies utilize a traditional architectural top-down approach to sustainable building design practices that consumes financial and temporal resources early in the design process. By identifying the array mechanical subsystems required...

Describing Tsunami Inundation and Debris Motion using Optical Measurement Methods in a Large-Scale Wave Basin

Creator:: Rueben, Matthew Robert
Abstract:: This thesis consists of two papers in manuscript format. The first paper presents optical measurements of tsunami inundation through an urban waterfront in a laboratory wave basin. The physical model was constructed at 1:50 scale and was an idealization of the town of Seaside, Oregon. The paper presents an analysis...

Experimental study of impulse turbines and permanent magnet alternators for pico-hydropower generation

Creator:: Cobb, Bryan R.
Abstract:: Increasing access to modern forms of energy in developing countries is a crucial component to eliminating extreme poverty around the world. Pico-hydro schemes (less than 5-kW range) can provide environmentally sustainable electricity and mechanical power to rural communities, generally more cost-effectively than diesel/gasoline generators, wind turbines, or solar photovoltaic systems....
