  • 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...

  • Experimental Study of the Impact of Physical and Chemical Properties on Smoldering Combustion in Natural Fuels

    Creator:
    Smucker, Benjamin
    Abstract:
    Smoldering combustion in wildland fires is difficult to extinguish, can transition to flaming combustion, and produces a significant amount of pollutants. It is necessary to understand parameters controlling smoldering in order to help predict the smoldering behavior and potentially mitigate these hazards. The wide variety of natural fuels that occur...

  • The Influence of Fuel Characteristics on Smoldering Behavior through Porous Fuels

    Creator:
    Ross, Andrew H.
    Abstract:
    Smoldering can play a dangerous role in the ignition and spread of wildfires. Naturally occurring fuels consist of multiple layers of organic materials with varying particle sizes due to differences in decomposition stages with fuel depth, yet the influence of particle size on burning behavior is poorly understood. Previous research...

  • Ignition of Fuel Beds by Firebrands

    Creator:
    Bean, Derek R.
    Abstract:
    The severity of wildfires around the globe is increasing. At the same time, urban development is expanding outward into areas where severe fires occur. There is an increased risk of home loss to fires in areas where severe fires and urban expansion meet. Ignition of homes or nearby fuel is...

  • Fouling Characterization in Hypersaline Wastewater Treatment

    Creator:
    Messer, Morgan S.
    Abstract:
    Water supplies are diminishing worldwide and by 2025 two thirds of the population could be living in regions of water scarcity (local demand for water is greater than water supply). One method to increase available water sources is to use desalination technologies to separate water from saline solutions. While desalination...

  • Experimental Investigation of Near-Critical Carbon Dioxide in Microchannels for High Flux Cooling Applications

    Creator:
    Travers, Kristen
    Abstract:
    With the continued decrease in size and subsequent increase in power of computer processors, thermal management in electronics is becoming more important than ever before. The chip heat densities are reaching new peaks (> 100 W cm-2) that current cooling methods are not able to keep up with. However, some...

  • Influence of Two-Phase Fuel on Detonation Behavior

    Creator:
    Barlow, Dustin
    Abstract:
    Detonation combustion is of great interest for propulsion devices because of its potential to increase thermodynamic efficiency, reduce the weight of current gas turbine engines, and rapidly accelerate to high Mach numbers. Detonation engines might also have the ability to decrease harmful exhaust products from traditional propulsion methods. In order...

  • 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,...

  • The energy extraction performance of an oscillating rigid and flexible foil

    Creator:
    Totpal, Alexander D.
    Abstract:
    The aerodynamic performance of an oscillating pitching and plunging foil operating in the energy harvesting mode is investigated. Experiments are conducted in a closed-loop recirculating wind tunnel at Reynolds numbers of 24,000 to 48,000, and reduced frequencies (k = fc/u) of 0.042 to 0.083. Foil kinematics are varied through the...

  • Potential of Genetic Algorithms for Design of Liquid Cooled Heat Sinks Fabricated Using Additive Manufacturing

    Creator:
    Dokken, Connor B.
    Abstract:
    The advancement of new manufacturing techniques such as additive manufacturing enable significantly greater freedom of design compared to conventional techniques. Of significant interest is what improvements could be made in the design of cold plates and heat sinks for electronics cooling. Greater design freedom could potentially enable new designs that...

    Yates, Connor L.
    Abstract:
    Multi-robot teams offer promising solutions for many long term deployments in remote and dangerous domains, such as extraterrestrial or underseas exploration. However, long term deployments present many problems preventing robot teams from operating effectively. Learning over long time scales is makes it difficult to assign credit to robots' actions, as...

  • Turbulent Heat Transfer of Supercritical Carbon Dioxide in the Proximity of the Pseudo-Critical Point with Non-Uniform Heat Flux Boundary Conditions

    Creator:
    Jajja, Saad A.
    Abstract:
    Seven decades of supercritical heat transfer research have not seen an attempt to characterize turbulent thermal transport in internal flows subject to asymmetric heating. Existing heat transfer models therefore do not account for phenomena that dictates thermal transport, in the proximity of the pseudo-critical point, for non-uniform heating. Additionally, past...
