The effects of pulsing and blowing ratio on a 45° inclined jet in cross flow

Creator:: Stander, Arjan
Abstract:: The effect of jet flow pulsing and blowing ratio on a jet in cross flow has been investigated. Preliminary jet flow studies were performed without cross flow and an extensive study of jet with cross flow was done for a total of nine test cases. The effect of velocities ratios...

Processing of laser interferometric signals for small displacement measurements

Creator:: Peng, Gwo-sheng
Abstract:: Algorithms for analyzing laser interferometry signals were developed and adopted to the computer based processing of small displacement measurements. These methods, matrix operation approach and fixed parameters approach, are based on signal phase calculation and are able to replace complex fringe counting electronic circuits. The matrix operation provides an approach...

Analysis and simulation of dual-source heat pumps with three-fluid evaporators

Creator:: Lee, Jai-hyo
Abstract:: When the ambient temperature drops, air-source heat pumps deliver less heating per unit of power input and usually cannot provide for the heating load. Therefore, dual-source heat pumps can offer an attractive alternative. In the context of this work, a dual-source heat pump operates as an air-source unit under normal...

An experimental investigation of radiative and total heat transfer around a horizontal tube immersed in a high temperature gas-solid fluidized bed

Creator:: Alavizadeh, Seyed Nasser
Abstract:: This study is primarily concerned with the measurement of the local radiative component of total heat transfer around a horizontal tube immersed in a large particle fluidized bed at elevated temperatures.Total heat transfer was also measured in order to assess the relative radiation contribution.The radiation measurement probe employs a silicon...

Three-dimensional, nonlinear viscoelastic analysis of laminated composites : a finite element approach

Creator:: Wang, Min
Abstract:: Polymeric composites exhibit time-dependent behavior, which raises a concern about their long term durability and leads to a viscoelastic study of these materials. Linear viscoelastic analysis has been found to be inadequate because many polymers exhibit nonlinear viscoelastic behavior. Classical laminate theory is commonly used in the study of laminated...

Experimental evaluation and numerical modeling of a water source heat pump evaporator

Creator:: Means, Paul Morency
Abstract:: Water source heat pumps are increasingly being used for residential and commercial space heating. Typically, these heat pumps are capable of both heating and cooling, and historically the design emphasis has been on improving the units' cooling performance. Recently, there has been more interest in improving the heating performance, however,...

Testing and design procedures for electric propellant pumps for suborbital bi-propellant rockets

Creator:: Verna-Ketel, Dominic
Abstract:: An electrically driven propellant pump (HALE E-Pump) was analysed and tested to determine its viability for use in a bi-propellant launch vehicle for the High-Altitude Liquid Engine (HALE) student rocket team at Oregon State University (OSU). The pump, manufactured in 2022 by students in OSU machine shops, was hydrostatically tested...

An analysis of peripheral milling of finger-joints in ponderosa pine cut-stock

Creator:: Liu, Yongsheng
Abstract:: To make low grade lumber into high-valued products, finger-jointing is a widely used method in the timber industry. In certain situations, chip-out occurs degrading the quality of the joint. To better understand the machining process, a beam-type dynamometer based on strain gages was designed to analyze the dynamic cutting forces...

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...

Evaluation of system-level performance of closed thermochemical energy storage systems for space heating

Creator:: Rivera, Kate E.
Abstract:: This study evaluates the system efficiency and energy-offsetting capabilities of a closed-cycle thermochemical energy storage (TCES) system. Current TCES research primarily focuses on material selection and reactor design but overlooks the practical limitations faced on a system level. Thus, this study investigates various TCES integration methods for providing building space...
