  • Fluidized Bed Reactor Engines

    Creator:
    Lavrich, Zoe A.
    Abstract:
    Repurposing internal combustion engines as petrochemical reactors (i.e., Reactor engines) could offer a smaller, scalable alternative to traditional full scale chemical processing facilities. For many chemical processes, incorporating catalyst particles in fluidized beds is expected to result in superior performance over both monoliths and packed beds. Conversion of ethane into...

  • Wave Energy Converter Array Optimization : Algorithm Development and Investigation of Layout Design Influences

    Creator:
    Sharp, Christopher J.
    Abstract:
    Realizing the vast amount of energy available in ocean waves, an industry has emerged that is progressing towards the deployment of grid–connected wave energy converters. Likely to be deployed in arrays, a challenge to the wave energy industry is maximizing the energy production of such arrays. We have been developing...

  • A force plate for measuring contact forces during dependent transfers onboard aircraft

    Creator:
    Schafer, Christopher A.
    Abstract:
    The transfer of air travelers with disabilities between a mobility aid and an aircraft seat is a major source of injury for both the travelers and the airline personnel assisting in the transfer. The risk to both parties might be reduced through the biomechanical study of the transfer task. Such...

  • Aircraft wing optimization using B-spline models and panel methods

    Creator:
    Jackson, Danielle Monique
    Abstract:
    This research investigates shape optimization process, using b-spline models and panel methods, to achieve a high lift to drag ratio for an aerodynamic structure. This research is a proof of concept for further research in aerodynamic shape optimization. The coupled process, involving the design and optimization of a random shape,...

  • Bi-level flexible-robust optimization for energy allocation problems

    Creator:
    Biswas, Arpan
    Abstract:
    A common problem in energy allocation problems is managing the trade-off between selling surplus energy to maximize short term revenue, versus holding surplus energy to hedge against future shortfalls. For energy allocation problems, this surplus represents resource flexibility and is quantified as the surplus energy after meeting the demand. The...

  • Topological Design Considering Uncertainty and Hyperelasticity

    Creator:
    Pham, Trung
    Abstract:
    Topology optimization (TO) is a mathematical method to find the optimal size, shape and connectivity of a domain under specified conditions, and has had many applications in engineering design. However, challenges remain in realizing TO as an effective design tool for many design situations. Uncertainty is ubiquitous in nature and...

  • Resilient Design for Complex Engineered Systems in the Early Design Phase

    Creator:
    Keshavarzi, Elham
    Abstract:
    There are many uncertainties that complex engineered systems will face throughout their lifecycles due to changes in internal and external conditions. It is desirable for complex engineered systems to be resilient against various uncertainties. The ability to overcome such uncertainties should be embedded into the system from the beginning. However,...

  • From Functional Modeling to Optimization : Risk and Safety in the Design Process for Large-Scale Systems

    Creator:
    McIntire, Matthew G.
    Abstract:
    In order to more effectively design large, complex systems, risk must be accounted for throughout the design process. A systematic way to account for risk is by using system model simulation. During the conceptual design phase, functional models can be drawn to help the engineer design their system's functional architecture....

  • 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...

  • Transient analysis of a tennis racket using PC-based finite elements and experimental techniques

    Creator:
    Jenkins, Christopher H. M.
    Abstract:
    Only very recently has modern technology been applied to the design of the tennis racket. In fact, the tennis player of a few hundred years ago would easily recognize today's racket. Although the literature reveals a surprising number of studies on racket mechanics, little work has been reported on the...
