  • Sources of flow maldistribution in microreactor-assisted synthesis of ceria nanoparticles

    Creator:
    Tseng, Chih-Heng
    Abstract:
    Recent efforts show that microchannel technologies have much to offer the field of nanomanufacturing: the structuring of matter on the order of one billionth of a meter. During the synthesis of nanomaterials, microchannel reactors take advantage of large surface-to-volume ratios to accelerate heat and mass transport. This accelerated transport allows...

  • The fracture toughness of medium density fiberboard and other fiber bridging composites

    Creator:
    Matsumoto, Noah T.
    Abstract:
    In many composites, fiber bridging develops as part of the fracture process. Fiber bridging invalidates many toughness evaluation methods such as the ASTM E399 and complicates the identification of crack length, which is a necessary parameter in energy methods. In order to measure the toughness of fiber bridging composites, an...

  • An analytical methodology to support the identification and remediation of potential human fallibilities in complex human-machine systems

    Creator:
    Thompson, Leslie Braitsch
    Abstract:
    This research proposes a Human Fallibility Identification and Remediation Methodology (HFIRM) that supports the systematic identification and remediation of potential human errors. The objective of this research was to develop and test a prototype framework that supports the practical application of human factors knowledge to the analysis and design of...

  • Design of an automated system for imaging and sorting soil mesofauna

    Creator:
    Chamblin, Mike A.
    Abstract:
    Identification and population counts of soil mesofauna can be an important tool for soil ecologists to determine the soil biodiversity. Information provided from population counts can give insight to soil ecologists about the effects of human land use, monitoring soil and water health, benefits of soil biodiversity in agriculture, and...

  • Experimental study of two-phase gas-liquid flow in a microscale fractal-like branching flow network

    Creator:
    Kwak, Younghoon
    Abstract:
    Two-phase gas-liquid flows in microscale fractal-like branching channel flow networks were experimentally studied to assess the validity of existing void fraction correlations and flow regimes based on superficial gas and liquid velocities. Void fractions were assessed using two different methods. First, void fraction data were acquired using a High-Speed-High-Resolution (HSHR)...

  • Thermally actuated pumping of a single-phase fluid using surface asymmetry

    Creator:
    Jo, Myeong Chan
    Abstract:
    An experimental study of thermally actuated pumping of a single-phase, single-component fluid is presented in the context of thermal management of a heat source. The prominent feature of this pumping method is that the very heat that is to be removed from the heat source causes a net fluid motion....

  • Mixed reactant single chamber fuel cell, using products generated from the electrolysis of an aqueous electrolyte

    Creator:
    Jost, William C.
    Abstract:
    A Mixed Reactant Single Chamber (MRSC) Fuel Cell is a relatively recent concept in the field of fuel cell engineering originally developed in the late 1950’s. Typical fuel cells have separated reactants (a separated fuel and oxidizer) that react on their usually non-selective electro-catalytic materials. A mixed reactant fuel cell...

  • Detection and analysis of separated flow induced vortical structures

    Creator:
    Snider, Stephen David Louis
    Abstract:
    Flow separation is an important phenomenon in fluid dynamics because of the effect it has on lift and drag on immersed bodies. Areas of swirl within a separated flow region may have a distinct effect on the surface forces, modifying the lift and drag characteristics. A correlation between the passage...

  • Micro adiabatic combustion engine : concept development, simulation and combustion experiments

    Creator:
    Chewning, Scott R.
    Abstract:
    The current proliferation of portable electronic devices for personal communication, business and entertainment has created a demand for high energy density power supplies. A hydrocarbon fuel with a conversion efficiency of over 15% can provide greater energy density than current battery technology for these applications. Current micro-scale heat engines do...

  • Applying hierarchical and adaptive control to coordinating simple robots

    Creator:
    Knudson, Matthew D.
    Abstract:
    Coordinating multiple robots to achieve a complex task requires solving two distinct control problems: the high-level control problem of ensuring that each robot aims to perform a useful task (e.g., coordination) and the low-level control problem of ensuring that each robot actually performs the correct actions to achieve its task...
