  • CFD Verification, Validation, and Sensitivity Study of Internally Heated Concentric Tube Thermosyphon O-SERTTA

    Creator:
    Miller, Jaden
    Abstract:
    Irradiation experiments are a critical aspect of the nuclear fuels and materials qualification process. Determining the flow conditions of these experiments is necessary for understanding response of nuclear components during transient and normal operation. Quality flow data is lacking for cartridge-type irradiation experiments with annular flow natural circulation designs. Data...

  • Melting Stage Analysis for Indirect Freeze Desalination

    Creator:
    Pratt, Mason G.
    Abstract:
    To investigate the melting stage of indirect freeze desalination three numerical models were developed. A zeroth, first, and second order analyses modeled the melting of ice around the outside of a pipe as a function of time. The zeroth order analysis assumes the system to be steady state. The first...

  • Evaluation of the predictive capability of two-phase flow maps for microchannel condensation of R-134a at low mass flux conditions

    Creator:
    VanderPutten, Michael A.
    Abstract:
    Predicting condensation flow regimes and the associated heat transfer and pressure drop in microchannels is critical for designing terrestrial and space systems for heating, cooling, power generation, and advanced manufacturing. It is well established that in flows approaching the microscale (Dh < 1 mm) gravity-dominated flow regimes become less relevant,...

  • A Computational Fluid Dynamics Study on the Hydrodynamics for Tandem Plate Configurations under Turbulent Flow

    Creator:
    Gjemso, Jonathan
    Abstract:
    The subject of fluid-structure interactions (FSI) are a matter concerning the design of any element immersed in a fluid. One of the most critical phenomena embedded within the scope of FSI is the creation of vortex-induced vibrations (VIV). These type of vibrations originate in a given body as a result...

  • Freeze Stage Analysis of an Indirect Freeze Desalination System

    Creator:
    Whitaker, Trevor A.
    Abstract:
    Freeze desalination poses as a potential solution to many of the issues that accompany current desalination methods. The research detailed in this manuscript involves creating and analyzing a numerical model of the freezing operation of an indirect contact freeze-melting (FM) desalination system. In this initial analysis, pure water is frozen...

  • A Computational Investigation of Natural Circulation Effects on Heat Transfer Coefficient and Friction Factor

    Creator:
    Buskirk, John
    Abstract:
    The nuclear industry has shown a large interest in natural circulation driven passive cooling systems following the Fukushima nuclear accident. Despite this interest, there is no widely used heat transfer correlation or friction factor correlation developed for natural circulation driven flow. A CFD analysis including grid convergence testing using Fluent...

  • Design of a Biomass Feeding Robot for Controlled Cookstove Testing

    Creator:
    O'Boyle, Duncan
    Abstract:
    The purpose of this report is to detail the design and validation of a prototype robot that feeds biomass into a range of small household cookstoves at a programmable rate. Improved design and testing methods for the development of improved biomass cookstoves are needed to design stoves that alleviate the...

  • 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...

  • Proximity Activated Stimuli on Modified Ride-On-Cars for Children with Disabilities

    Creator:
    Weathers, Thomas S.
    Abstract:
    This thesis describes the implementation of ultrasonic sensors to trigger a stimulus to increase peer interaction for children with disabilities using modified ride-on-cars for mobility. Modified ride-on-car technology has improved mobility for children with disabilities by effectively replicating the social benefits of a powered mobility device, yet there are opportunities...

  • Preliminary Numerical Study of a Condenser Using Fractal-Like Patterned Hydrophobic and Hydrophilic Strips

    Creator:
    Lazaroff, Spencer A.
    Abstract:
    Condensers are vital components of power plants and are often one of the most major cost concerns when planning construction. Generally speaking, the surface area required to dissipate the heat generated in the boiler is so great that enormous and expensive structures are necessary. The usage of a hybrid surface...
