  • Probabilistic Wind Power Forecasting for Hybrid Systems

    Creator:
    Irmas, Cameron
    Abstract:
    Wind power forecasting provides valuable insights for demand response, energy market operation, and plant control optimization. Probabilistic approaches—which capture uncertainty in these complex systems by representing predictions as probability distributions—represent a growing area of research in wind energy science. However, their applications for wind-based hybrid systems, particularly those focused on...

  • Realized regulatory complexity : unveiling the hidden effect of regulation structure on product architecture

    Creator:
    Robinson, David Myles
    Abstract:
    Government regulation is an established policy tool for inducing technological innovation in a market. For example, many environmental regulations prescribe performance requirements that industry complies with by innovating aspects of the product design. These design innovations might include updated components, new functionality, or a revised product architecture. However, the effect...

  • Operation of a High-Temperature Oxidation Reactor for Thermochemical Energy Storage

    Creator:
    Ramsey, Owen C.
    Abstract:
    The cost of long-duration energy storage poses one of the most significant limitations on the penetration of renewables into power grids. Thermochemical energy storage has great potential to reduce this cost through the use of a reversible redox reaction pair that has a high enthalpy of reaction. The chemical nature...

  • A methodology for iterative design using physical test data

    Creator:
    Morris, Wesley T.
    Abstract:
    This thesis addresses a common knowledge gap that was identified amongst the Society of Automotive Engineers (SAE) competition design teams at Oregon State University. Students that join the SAE teams at Oregon State University typically do not have experience using physically collected data during a design process. This leads to...

  • Exploring the Ductility Minimum of Niobium C103 at Intermediate Temperatures using Triaxial Tensile Specimens

    Creator:
    Wood, Thomas N., II
    Abstract:
    This work explores the mechanical properties of single-phase niobium alloy C103 from room temperature to 600°C for the purpose of expanding safe uses of the material into new applications. The study utilizes a symmetrically notched triaxial tensile specimens to manipulate the internal stress field in order to observe the changes...

  • Modeling hop kilning with respect to energy consumption and drying kinetics

    Creator:
    Thomas, Matthew W.
    Abstract:
    Currently, little work has been performed studying energy consumption in hop kilning. This thesis explores drying with an alternative drying schedule that extends the initially elevated drying temperature currently used by growers and examines its impact on drying time and energy use. Extending the time of the initially elevated drying...

  • Simulating Soot Formation and Growth using a Parallel Coupled Monte Carlo Method

    Creator:
    Peters, Jordan
    Abstract:
    Small hydrocarbon particles such as soot and soot precursors pose a serious threat to human health and Earth's climate. Understanding the mechanisms by which soot particles form and grow is the first step to reducing the prevalence of these particles. Computational simulations are used to investigate combusting systems which are...

  • 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 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...
