  • Generalized Preconditioning to Accelerate Simulations with Large Multiphase Chemical Kinetics Models

    Creator:
    Walker, Anthony S.
    Abstract:
    Combustion emissions produced from burning real transportation fuels have many environmental impacts. However, detailed chemistry across multiple phases, time scales, and thermodynamic conditions make predicting combustion emissions challenging. Detailed modeling of the gas phase alone is prohibitively expensive, due to the large size and stiffness of the kinetic models. The...

  • Numerical Analysis of Experimental Impacts on Wind Turbine Blades

    Creator:
    Fleiger-Holmes, Kahlan
    Abstract:
    Wind energy is one of the fastest growing renewable forms of energy in the United States and the world. However, interactions between wind turbines and wildlife have the possibility to injure animals such as birds and bats. Strategies to assess and minimize wind turbine interactions with wildlife are critical for...

  • Validation of Design For Additive Manufacturing Heuristics for Aperiodic Structures through Application to Regular Structures

    Creator:
    Schipper, Paxton
    Abstract:
    Aperiodic structures cause significant challenges to subtractive manufacturing methods due to the common features such as inaccessible voids within the structure. Additive man- ufacturing presents an appealing alternative for this purpose. The aim of this research is to test analysis heuristics for validity through application to periodic structures. First, a...

  • Student Club Analysis: The Effects of Organizational Structuring on Competition Performance

    Creator:
    Chandler, Jacob J.
    Abstract:
    This thesis aims to explore the effects of organizational and management principles within the context of a student club – an international Formula Student team. Research on the effects of organizational structuring on student club performance tends to be qualitative in nature. While considering the inherent complexity of the human...

  • Numerical Modeling of Powder Metallurgy Hot Isostatic Pressing

    Creator:
    Sobhani, Samaneh
    Abstract:
    Powder Metallurgy Hot Isostatic Pressing (PM-HIP) is a widely recognized powder metallurgy manufacturing process to produce near-net-shape and net-shape components. During general PM-HIP processes the metal powders are filled within a capsule (die), heated and loaded with high pressure simultaneously, and solidified to form the final product. Due to the...

  • Electrical Conductivity of Ceramic Material at High Temperature

    Creator:
    Kangsathein, Parm
    Abstract:
    The electrical conductivity data of ceramic material at high temperatures can be useful in the application of modeling, solid oxide fuel cell (SOFC), and magnetohydrodynamic (MHD). The existing data is considerably lacking at extreme temperatures. Our research focuses on bridging this gap by reporting the electrical conductivity measurements of sets...

  • Multi-modal sensing data fusion for machining and additive manufacturing

    Creator:
    Fu, Xianzhe
    Abstract:
    With the increased demand for high-quality products, reliable and robust process monitoring has become a key capability for modern manufacturing systems. Through sensors installed in the machinery, the real-time information was measured to assess the state of the processes. The measured data can be used to infer the mechanical, material,...

  • 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...

  • 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...

  • Functional analysis to inform early design decisions for novel systems with substantial operations and maintenance costs

    Creator:
    Algarra, Nathan
    Abstract:
    Long field-life systems are those for which operational, as opposed to capital, expenditures dominate the life time cost of the system. In established product categories, operational experience and historical maintenance data allows engineers to make informed decisions influencing maintenance during the early design stages when design changes are at their...
