Heat transfer in magnetic fluids at low Reynolds number

Creator:: Choi, Sang Hyouk
Abstract:: This study was concerned with the flow of a magnetic self-propelled ferrohydrodynamic fluid in a horizontal circular tube subjected to axially varying temperature and magnetic field. The first phase of the study involved the analytical solution to the governing equations for the velocity and temperature profiles within the fully developed...

Large displacement, high Reynolds number oscillating cylinder

Creator:: Chan, Yau Wai
Abstract:: Hydrodynamic forces on a cylinder oscillating horizontally underwater with its axis perpendicular to the motion were measured at the Oregon State University Wave Research Facility. The cylinder had an outer diameter of 12 inches and a length of 12 feet. For the data presented herein, the maximum displacement of the...

An Engineering Decision Support System (EDSS) with alternative-criterion pair evaluations

Creator:: Herling, Derald E.
Abstract:: An Engineering Decision Support System, EDSS, was developed using Bayesian mathematics which incorporates knowledge and confidence components observed in alternative-criterion pair decision making. The separation of knowledge and confidence has been previously unaccounted for in decision-making methods. EDSS provides decision support to individuals or teams which must make choices between...

Experiments on a low aspect ratio wing at low Reynolds numbers

Creator:: Morse, Daniel R.
Abstract:: At the start of the 21st century much of the focus of aircraft design has been turned to unmanned aerial vehicles (UAVs) which generally operate at much lower speeds in higher risk areas than manned aircraft. One subset of UAVs are Micro Air Vehicles (MAVs) which usually are no larger...

A numerical study of inertial flow features in moderate Reynolds number flow through packed beds of spheres

Creator:: Finn, Justin Richard
Abstract:: In this work, flow through synthetic arrangements of contacting spheres is studied as a model problem for porous media and packed bed type flows. Direct numerical simulations are performed for moderate pore Reynolds numbers in the range, 10 ≤ Re ≤ 600, where non-linear porescale flow features are known to...

Experimental Investigations of the Unsteady Aerodynamics of Oscillating Airfoils Operating in the Energy Harvesting Regime

Creator:: Siala, Firas F.
Abstract:: The rising global trend to reduce dependence on fossil fuels has provided significant motivation toward the development of alternative energy conversion methods and new technologies to improve their efficiency. Recently, oscillating energy harvesters have shown promise as highly efficient and scalable turbines, which can be implemented in areas where traditional...

Data Mining a Design Repository for Automating and Validating Functional Modeling

Creator:: Mikes, Alex B.
Abstract:: The purpose of this work is to build a foundation of understanding and methodologies as the steps toward automating functional modeling. We have achieved significant progress in the automatic generation of functional representations, which can be connected at the interface of components to create a functional model. This work highlights...

Heat Treatment Effects on the Mechanical Properties and Microstructure of CPM-M4 Tool Steel

Creator:: Fast, Cody P.
Abstract:: Variations in heat treatments have significant effects on the microstructure of tool steels. For CPM-M4 tool steel, the changes in microstructure and mechanical properties were observed based off of variations in temperature. Five heat treatments with constant exposure time and variable austenitizing and tempering temperatures were performed on samples of...

An analytical model of radiative and convective heat transfer in small and large particle gas fluidized beds

Creator:: Fatani, Abdulhadi Ahmed
Abstract:: A complete analytical model of radiative and convective heat transfer to a horizontal tube in small and large particle gas fluidized beds has been developed. In the model the bed of particles consists of an emulsion phase and a bubble phase. The emulsion phase is approximated by a series of...
