  • 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...

  • 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...

  • 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,...

  • 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...

  • 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...

  • High Temperature Electrical Properties of Ceria-Based Ceramics for Use as Electrodes in Magnetohydrodynamic Power Generators

    Creator:
    Bowen, Michael S.
    Abstract:
    Determining the electrical properties of ceria-based materials is important for their use as electrodes in hot-wall magnetohydrodynamic (MHD) power generators with wall temperatures greater than 1500 ̊C. The electrical conductivity of a material can be used in models for predicting the performance of generator designs. More specifically, the temperature dependent...

  • Generalized Chip Formation and Thermal Dynamics of Modulated Turning

    Creator:
    Ozdemir, Mert
    Abstract:
    Modulation assistance is widely employed to improve chip management in turning. This process is also known as modulated turning. Modulated turning transforms continuous cutting into intermittent cutting by periodically disengaging the tool tip from the workpiece, resulting in the generation of short, easily managed chips. This novel method improves the...

  • Development and validation of acoustic measurement techniques for void fraction in concentric annular geometries

    Creator:
    Tost, Brian C.
    Abstract:
    This work investigates the acoustic velocity of gas-liquid mixtures in vertical, co-current flow in a concentric annulus. Acoustic velocity shows promise as a detection parameter for the presence and amount of gas in a liquid flow because of its high sensitivity to gas void fraction in a gas-liquid mixture. However,...
