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...

An experimental/analytical investigation of buoyant jets in shallow water

Creator:: Hsiao, Entsung
Abstract:: This thesis presents the results of an experimental and analytical study of single-port buoyant turbulent jets discharged into shallow water. The experimental results include the measured downstream dilution, centerline concentration and trajectory. Independent parameters considered were Froude number, submerged depth, discharge angle and velocity ratio. Results indicate that decreasing the...

Micro adiabatic combustion engine : concept development, simulation and combustion experiments

Creator:: Chewning, Scott R.
Abstract:: The current proliferation of portable electronic devices for personal communication, business and entertainment has created a demand for high energy density power supplies. A hydrocarbon fuel with a conversion efficiency of over 15% can provide greater energy density than current battery technology for these applications. Current micro-scale heat engines do...

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...

The fracture toughness of medium density fiberboard and other fiber bridging composites

Creator:: Matsumoto, Noah T.
Abstract:: In many composites, fiber bridging develops as part of the fracture process. Fiber bridging invalidates many toughness evaluation methods such as the ASTM E399 and complicates the identification of crack length, which is a necessary parameter in energy methods. In order to measure the toughness of fiber bridging composites, an...

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...

Exploration of the Integration of Markerless Motion Capture and Virtual Reality for Ergonomics Assessment of Products in Early Design

Creator:: Zhang, Jianfu
Abstract:: This thesis uses the manuscript option. The First Manuscript proposed a markerless Motion Capture (MOCAP) system with a Virtual Reality (VR) setup, which has the potential to eliminate excess cost and time associated with physical prototyping. Validation of the proposed virtual ergonomics analysis was made by measuring L4/L5 compression forces....

Off-design analysis and control of a wood-fired combined-cycle power plant

Creator:: Brawn, Robert Charles
Abstract:: This report presents the off-design analysis of various wood-fired combined-cycle power plants using a computer model to simulate plant performance. The combined-cycle systems investigated are characterized by having a woodfueled combustor, an indirect-fired gas turbine, and a Rankine steam cycle. This work was conducted as part of a larger biomass...
