  • Preliminary Numerical Study of a Condenser Using Fractal-Like Patterned Hydrophobic and Hydrophilic Strips

    Creator:
    Lazaroff, Spencer A.
    Abstract:
    Condensers are vital components of power plants and are often one of the most major cost concerns when planning construction. Generally speaking, the surface area required to dissipate the heat generated in the boiler is so great that enormous and expensive structures are necessary. The usage of a hybrid surface...

  • Conservation of Mass in a Piping Network

    Creator:
    Heim, Samantha
    Abstract:
    Using returnable bottles within a brewery setting can lower costs associated with purchasing new bottles as well as reduce the energy associated with recycling glass bottles. A commercial dishwasher was retrofit specifically to wash bottles. The design and assembly of the piping flow network, testing of water flow through the...

  • Void fraction variations in a fractal-like branching channel network

    Creator:
    Cullion, Rebecca
    Abstract:
    Two-phase flow in a fractal-like branching microchannel heat sink may have enhanced heat transfer capabilities over single phase flow in the same branching channel network. In order to exploit this potential, a complete understanding of flow boiling in this geometry is required. The fractal-like geometry is similar to that of...

  • Systemic barriers encountered by Latinas in engineering

    Creator:
    Coto, Paula
    Abstract:
    Latinas in engineering face discrimination on the intersectionality of their two identities, Latinx and woman. The barriers that happen to them as an indirect effect of previous or existing institutional systems of oppression are called systemic barriers. Coming from the lens of four subjects, in a ranking of the barriers...

  • Analysis of Staged Hydraulic Air Compressors

    Creator:
    Shibley-Styer, Ian
    Abstract:
    To investigate the viability of staging hydraulic air compressors (HACs), a model for HACs operating with a closed loop water cycle powered by a pump was made. This model was used to simulate how these HACs would respond to variable heights and mass flow ratios for both single-stage and multi-stage...

  • On the optimization of performance in fractal-like branching microchannel heat transfer devices

    Creator:
    Heymann, Douglas Benjamin
    Abstract:
    Fractal-like branching microchannel flow networks have been found to improve wall temperature uniformity and decrease both pressure drop and flow power compared to arrays of straight microchannels. The present study seeks to maximize the benefits of fractal-like branching channels by means of a gradient-based optimization algorithm. The algorithm identifies the...

  • Performance and flow stability characteristics in two-phase confined impinging jets

    Creator:
    Sabo, Michael D.
    Abstract:
    Advances in electronics fabrication, coupled with the demand for increased computing power, have driven the demand for innovative cooling solutions to dissipate waste heat generated by these devices. To meet future demands, research and development has focused on robust and stable two-phase heat transfer devices. A confined impinging jet is...

  • Microscale thermal management utilizing vapor extraction from a fractal-like branching heat sink

    Creator:
    Apreotesi, Mario A.
    Abstract:
    It is hypothesized that increases in pressure drop due to vapor generation during boiling in microchannels can be reduced by extraction of vapor at its point of inception. Ultimately, this local vapor extraction decreases the pressure drop required to drive the flow through a fractal-like branching, microchannel flow network within...

  • Freeze Stage Analysis of an Indirect Freeze Desalination System

    Creator:
    Whitaker, Trevor A.
    Abstract:
    Freeze desalination poses as a potential solution to many of the issues that accompany current desalination methods. The research detailed in this manuscript involves creating and analyzing a numerical model of the freezing operation of an indirect contact freeze-melting (FM) desalination system. In this initial analysis, pure water is frozen...

  • An experimental study of co-flow ammonia-water desorption in an oil-heated, microscale, fractal-like branching heat exchanger

    Creator:
    Mouchka, Gregory A.
    Abstract:
    An experimental study was performed in which an ammonia-water solution was desorbed within a branching fractal-like microchannel array. The solution entered in the center of a disk, and flowed out radially until discharging in to a gravity-driven separation chamber. Heat was added to the ammonia-water through a thin wall, above...
