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...

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...

The experimental characterization of membrane behavior in two-phase gas extraction

Creator:: Cappello, Nicholas C.
Abstract:: Understanding the behavior of hydrophobic membranes is important for applications where separating a gas from a liquid-gas mixture is beneficial. For example, in-situ vapor extraction can be used in microscale heat sinks to improve heat transfer and flow stability. In this study, gas is experimentally evaluated flowing through flexible polytetrafluoroethylene...

Identification of Physical and Chemical Processes on Ignition and Burning of Live Fuels

Creator:: Fazeli, Hamid
Abstract:: Wildland fire refers to an unpredictable and uncontrollable fire that happens in wildland areas. Regardless of the beneficial impacts of wildland fires on ecosystems, the destructive impacts of wildfires on air quality, economy, public health, etc. are considerable. An essential goal in the fire community is that the wildland fires...

Proportional integral derivative control of an oil-heated fractal-like branching microchannel desorber

Creator:: Davis, Keith R.
Abstract:: A PID controller was designed to control the performance of an oil-heated fractal-like branching microchannel desorber for use in an ammonia-absorption refrigeration system. Both the amount and concentration of ammonia refrigerant generated at the desorber can be controlled by choosing the rectified circulation ratio as the controlled variable in a...

Mechanical Behavior of Elastomer Polymer under Shear and Compression: Experimental Investigation Using Digital Image Correlation

Creator:: Raheem, Hassan M.
Abstract:: Due to their viscoelastic properties, polymers and hydrogels are widely used in many applications. In this study, the viscoelastic properties of elastomer polymers were investigated for a series of hydrogel, hydrogel composites and silicon materials. A primary application for hydrogels and hydrogel composites is as a replacement for the degenerated...

Design of a single lamina for a microchannel dialyzer with a focus on bubble removal

Creator:: Mohammadi, Mahshid
Abstract:: A microchannel-based hemodialyzer offers a novel approach to hemodialysis practice and holds many promises for improving dialysis treatment efficiency and quality of life for kidney patients. The hollow fiber hemodialyzer, a conventional dialysis device, has certain limitations including non-uniformity of the dialysate flow path which necessitates the use of a...

Sustainable building design framework : an integrated approach

Creator:: Piacenza, Joseph R.
Abstract:: This paper combines two research publications working toward the development of an integrated framework for commercial sustainable building design. Current methodologies utilize a traditional architectural top-down approach to sustainable building design practices that consumes financial and temporal resources early in the design process. By identifying the array mechanical subsystems required...

Spatio – temporal temperature variations during droplet impingement evaporation : effects of nanofluid and nano-structured surface

Creator:: Graber, Christof
Abstract:: Droplet and spray impingement cooling are typically used in high heat flux thermal management. In this thesis, droplet impingement and evaporation heat transfer characteristics are determined from measured spatially- and temporally- varying fluid and surface temperatures. Unique to this study is the documentation of the effects of using a nanofluid...
