  • Manufacturing Process Design and Electrically-Assisted Embossing of a Microchannel Solar Receiver

    Creator:
    McNeff, Patrick S.
    Abstract:
    Manufacturing process design (MPD) represents a design-oriented approach to manufacturing engineering. In this dissertation, Haynes 230 (H230), a solid solution-strengthened Ni-based superalloy, was chosen to meet the material requirements of a microchannel solar receiver (MSR) needed to increase the efficiency and reduce the cost of solar thermal power generation. An...

  • Characterization and Prediction of Reactive Forces for Compressed 3D Printed Hyperelastic Lattice Structures

    Creator:
    So, David M.
    Abstract:
    In order to generate practical ways to easily design functional flexible lattice structures, this research seeks to find a way to predict reactive forces of compressed hyperelastic cubic lattice structures. Using 3D printed test coupons, material data was collected for use in finite element analysis. Cubic lattice structures with varying...

  • Manufacturing Process Design for a Stamped Microchannel High-Temperature Recuperator

    Creator:
    Song, Chuankai
    Abstract:
    Microchannel high temperature recuperators have the advantage of higher heat transfer coefficients and lower size and weight than traditional high temperature recuperators. However, the industrial application of microchannel recuperators are restricted by the high cost of photochemical machining and diffusion bonding. The objective of this paper is to introduce a...

  • A Manufacturing Process Design for Producing a Membrane-based Energy Recovery Ventilator with High Aspect Ratio Support Ribs

    Creator:
    Kawula, Steven P.
    Abstract:
    Heating, ventilation, and air conditioning systems represent nearly half of building energy usage in the United States. Recent building regulations requiring increased air turnover within buildings will result in even greater air conditioning usage. To alleviate these concerns, membrane-based heat-and-moisture exchangers known as energy recovery ventilators have been developed to...

  • Force Prediction in the Compression Sealing of an Ultra-thin Elastoviscoplastic Membrane

    Creator:
    McNeff, Patrick Scot
    Abstract:
    The objective of this paper is to demonstrate a method for mechanically characterizing a 25 μm thick elastoviscoplastic hemodialysis membrane and for quantifying the force required to use that membrane in compression sealing. First, methods are developed for mechanically characterizing the thin elastoviscoplastic membrane. Then, a finite element model is...

  • Application of controlled thermal expansion in diffusion bonding for the high-volume microlamination of MECS devices

    Creator:
    Pluess, Christoph
    Abstract:
    Diffusion bonding has been widely used within microlamination architectures for the fabrication of Micro Energy and Chemical Systems (MECS). MECS are microsystems with the ability to process bulk amounts of fluid within highly-parallel microchannel arrays capable of accelerated heat and mass transfer. Thus far, diffusion bonding of the microchannel arrays...

  • Development of nickel aluminide (NiAl) microchannel array devices for high-temperature applications

    Creator:
    Kanlayasiri, Kannachai
    Abstract:
    The miniaturization of Microtechnology-based Energy, Chemical and Biological Systems (MECS) is made possible by the use of high aspect ratio microchannel arrays to increase the surface-area-to-volume ratio of the flow conduits within the devices, resulting in an improvement in the heat and mass transfer performance of the devices. However, advantages...

  • Application of buckling behavior to evaluate and control shape variation in high-temperature microlamination

    Creator:
    Wattanutchariya, Wassanai
    Abstract:
    The miniaturization of energy, chemical and biological systems for distributed and portable applications, known as process intensification, is realized by the enhancement in heat and mass transfer performance within high surface-to-volume ratio microchannels. Fabrication of devices for process intensification is achieved in part by microlamination techniques. These techniques consist of...

  • Development of a passive micro-ball valve

    Creator:
    Wangwatcharakul, Worawut
    Abstract:
    A novel design, material, and fabrication method are presented to fabricate a passive micro-ball valve. Microvalves are critical components in microflow control devices used to control the fluid flows in microchannels. These microflow control devices can be integrated with microsensors to form micro analysis systems. Glass/silicon-based fabrication is complicated and...

  • Computer aided tolerance analysis and process selection for AutoCAD

    Creator:
    Pamulapati, Sairam V.
    Abstract:
    The fundamental objective of a design engineer in performing tolerance technology is to transform functional requirements into tolerances on individual parts based on existing data and algorithms for design tolerance analysis and synthesis. The transformation of functional requirements into tolerances must also consider the existing process capabilities and manufacturing costs...
