Power performance of planing boats with the effect of propeller selection and propeller guard design

Creator:: Ladd, Daniel M.
Abstract:: One of the unique problems associated with salmon gillnet fishing is of preventing the fouling of the boat's propeller in the net and associated fishing gear. Presently, the solution to this problem has been the addition of a basket type propeller guard which may produce a drag increase of 50...

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 study of high shear multiphase flow in a microchannel

Creator:: Morse, Daniel R.
Abstract:: Microscale fluid processes are an increasingly important subgroup of fluid mechanics. Applications for heat transfer and micro-electro-mechanical devices use flows on the scale of less than one hundred microns. This study is part of a larger work in which a multiphase, high shear environment is studied in a microchannel that...

A study of thermal stratification in the cold legs during the subcooled blowdown phase of a loss of coolant accident in the OSU APEX Thermal Hydraulic Testing Facility

Creator:: Wachs, Daniel M.
Abstract:: The phenomena of interest in this work is the thermal stratification which occurs during the early stages of a loss of coolant accident (LOCA) in the OSU APEX Thermal Hydraulic Test Facility, which is a scaled model of the Westinghouse AP600 nuclear power plant. Thermal stratification has been linked to...

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...

Effects of Channel and Ratchet Geometry on Passive Pumping in an Open-ended channel Configuration

Creator:: Daniels, Mitchell A.
Abstract:: Modern electronics have created increased demand for innovative cooling solutions. Typical forced convective cooling systems consist of pumps that circulate cooling fluid. However pumps can be unwieldy for many applications. This research is a continuation of work done at Oregon State University and Auburn University on the passive pumping of...

A study of the characteristics of oscillatory surface instabilities leading to droplet formation

Creator:: Daniels, Brian J.
Abstract:: The characteristics of the free surface in an orifice driven by a periodic forcing function have been studied both theoretically and experimentally. In the theoretical study, two wall boundary condition cases were examined: 1) the radial velocity at the wall of the orifice is zero; and 2) the axial velocity...

Numerical simulation of micro/mini-channel based methane-steam reformer

Creator:: Peterson, Daniel Alan
Abstract:: Numerical modeling of methane-steam reforming is performed in a micro/mini-channel with heat input through catalytic channel walls. The low-Mach number, variable density Navier-Stokes equations together with multicomponent reactions are solved using a parallel numerical framework. Methane-steam reforming is modeled by three reduced-order reactions occurring on the reactor walls. The surface...

Temperature Evolution of Nonreacting Spark Kernels at Sub-Atmospheric Pressures

Creator:: Caplan, Daniel L.
Abstract:: In the event of a mid-flight flameout of a gas turbine engine, reignition is paramount to occupant safety. Ignition at high altitude can be challenging, due in part to the potentially lower ambient pressures. An understanding of the effects of sub-atmospheric pressures on the temperature evolution of spark kernels is...

A Computational Framework for Resilience-Informed Design

Creator:: Hulse, Daniel E.
Abstract:: It is desirable for complex engineered systems to perform missions efficiently and economically, even when these missions' complex, variable, long-term operational profiles make it likely for hazards to arise. It is thus important to design these systems to be resilient so that they will actively prevent and recover from hazards...
