  • 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...

  • Novel architecture for entrapment of elastomeric membranes in microfluidic systems

    Creator:
    Blackwell, Edward P.
    Abstract:
    This thesis presents a novel microlamination architecture that enables the large scale integration of valves into low cost micro energy and chemical systems via membrane entrapment. Polycarbonate layers embossed with microfluidic channels were bonded by ultrasonic welding of raised embossed protrusions that penetrate though the PDMS membranes. The bonding pressure...

  • Uniform residence time in microreactor-assisted solution deposition of CdS thin-films for CIGS photovoltaic cells

    Creator:
    Hires, Clayton Lamar
    Abstract:
    Photovoltaic (PV) cells have long been an attractive alternative for the consumption of fossil fuels but current manufacturing practices suffer from poor energy efficiency, large carbon footprints, low material utilization, high processing temperatures and high solvent usage. A critical step in PV production is the deposition of CdS as a...

  • 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...

  • 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...

  • 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...

  • 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...

  • 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...

  • Sources of weld strength variability in capacitor discharge welding

    Creator:
    Benjarattananon, Jukchai
    Abstract:
    Capacitor discharge welding (CDW) is a rapid solidification joining process under the influence of one-dimensional thermal gradients. Although CDW is useful for joining small parts and dissimilar metals, CD welded joints have a large variability in weld strength. CDW is not widely accepted because of a lack of automated process...

    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...
