  • How personality affects creativity in concept ideation

    Creator:
    Berthelsdorf, Friederich A.
    Abstract:
    This thesis uses the manuscript option, and consists of a previously-published paper and a paper that has been accepted for publication. Manuscript One details an independent confirmatory study to Choo et al. (2014), which demonstrated that correlations exist between personality type and the outcome of concept ideation methods. This is...

  • Accelerating Power-to-Gas Energy Storage Through PEM Electrolyzer Development and Technoeconomic Forecasting

    Creator:
    Taie, Zachary
    Abstract:
    There is strong interest in the energy community to develop technologies that can diffuse low-cost, renewably generated electricity into difficult and slow to decarbonize sectors. One of the emerging areas of interest is renewable natural gas (RNG). RNG has low or no associated net greenhouse gas emissions and can be...

  • Numerical simulation of cavitating bubble-laden turbulent flows

    Creator:
    Shams Sobhani, Ehsan
    Abstract:
    Many engineering devices and propulsion systems suffer from undesirable effects of cavitation; such as degradation in the efficiency of pumps and turbines, generation of noise and vibration on ship propeller, increased drag and erosion of propeller blade, etc. In spite of decades of research on this problem, detailed study of...

  • Characterization of Two Novel Machining Processes for Difficult to Machine Materials

    Creator:
    Doran, Michael P.
    Abstract:
    New materials with superior mechanical properties, such as increased strength and hardness, have been developed to allow for new and improved products. However, the mechanical properties that make these materials useful also makes them difficult to process using conventional methods. New machining processes need to be developed to generate products...

  • Advanced Computational Modeling Methods for Floating Offshore Wind Systems

    Creator:
    Devin, Michael C.
    Abstract:
    Floating offshore wind energy is anticipated to become a competitive source of renewable energy by the late 2020s, but the industry must reduce costs and uncertainties associated with the technology to do so. Identifying solutions to these problems frequently relies on computational modeling, which presents technical shortcomings limiting the versatility...

  • Development of a remotely piloted aircraft for the Design/Build/Fly competition as a capstone engineering design project

    Creator:
    Wilcox, Joshua R.
    Abstract:
    The Design/Build/Fly competition (DBF) is an annual aerospace engineering competition hosted by the American Institute of Aeronautics and Astronautics (AIAA). Oregon State University's AIAA chapter competed for the first time at DBF in 2013 and finished in the top 25% which is a respectable finish for a first year team....

  • Design analysis using function-based failure propagation in failed system states

    Creator:
    Jensen, David Charles
    Abstract:
    For safety critical complex systems, reliability and risk analysis are important design steps. Implementing these analyzes early in the design stage can reduce costs associated with redesign and provide important information on design viability. In the past several years, various research methods have been presented in the design community to...

  • Evaporator analysis for application to water-source and ice-maker heat pumps

    Creator:
    Aceves, Salvador M.
    Abstract:
    Water-source and ice-maker heat pumps share many characteristics. However, each presents different technical difficulties that have prevented them from being used more widely. In a water-source heat pump a very important consideration is to reduce water consumption, while in an ice-maker heat pump a major concern is to reduce the...

  • Computer model for estimating cogeneration system performance and economic feasibility

    Creator:
    Simonds, John E.
    Abstract:
    Cogeneration is the simultaneous generation and use of both electricity (or mechanical power) and thermal energy from a single fuel source. It is a technology that has been used for years by industries, commercial institutions, and municipalities that need both heat and electrical power. An analytical approach has been developed...
