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...

Optimization of staged rankine energy conversion cycles for high efficiency

Creator:: Simmons, Larry Dean
Abstract:: Because of the fuel crisis and problems associated with thermal pollution there is new impetus and urgency for developing more efficient energy conversion systems for power generation. A preliminary analysis was undertaken to determine the potential of staged Rankine cycle systems for substantially higher efficiency. It was necessary to optimize...

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...

Optimization of Pulsed Laser Deposited Piezoelectric Thin Films for Microelectromechanical Systems

Creator:: Kearney, Dylan R.
Abstract:: Lead zirconate titanate (PZT) is well known to exhibit some of the strongest piezoelectric responses, explaining why it is at the heart of piezoelectric-based microelectromechanical systems (MEMS) research. The use of pulsed laser deposition (PLD) to synthesize PZT offers many advantages over alternative deposition techniques, mainly regarding its ability to...

Effect of lateral force on passenger comfort during a mechanically assisteddependent transfer

Creator:: Mast, Jonathan J.
Abstract:: Air travel presents several problems for passengers with disabilities. One in particular is how they get from their wheelchair and to an aircraft seat. The commonly used manual transfer method is hazardous to the assistants and the passenger. There are other alternatives, but they have plenty of room for improvement....

Solid/liquid phase change in small passageways : a numerical model

Creator:: Coven, Patrick J.
Abstract:: During the operation of phase-change ink-jet printers a bubble formation phenomenon often occurs. These bubbles are detrimental to the operation of the printer and substantial efforts are made to remove them. The objective of this research was 1: to develop a fundamental understanding of how bubble or void formation occurs...

An experimental study of natural convection heat transfer from a horizontal cylinder array vertically aligned to and confined by a single wall and two walls

Creator:: Al-Alusi, Thamir R.
Abstract:: Convection heat transfer was experimentally investigated for two different geometries. One case had three horizontal cylinders in a vertical plane placed between two vertical walls. The second case had three horizontal cylinders in a vertical plane with only one vertical wall. Several different cylinder center-tocenter spacings were investigated. The wall...

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...
