  • 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...

  • Design and Testing of the FUEL System: Integrating Engineering and Ethnographic Methods in Global Development Efforts

    Creator:
    Ventrella, Jennifer L.
    Abstract:
    Clean cooking technologies and fuels have been cited as a viable way to slow climate change and reduce the health and environmental impacts associated with traditional cooking devices used by 40% of the world. While engineers in the Design for Development sector have created hundreds of stove designs that perform...

  • Integrating sustainable manufacturing assessment into decision making for a production work cell

    Creator:
    Zhang, Hao
    Abstract:
    Sustainability has been the focus of intense discussions over the past two decades, with topics around the entire product life cycle. In the manufacturing phase, research has been focused solely on environmental impact assessment or environmental impact and cost analysis in its assessment of sustainability. However, few efforts have investigated...

  • Multi-Robot Coordination : Applications in Orchard Bin Management and Informative Path Planning

    Creator:
    Zhang, Yawei
    Abstract:
    Efficient coordination is desired for multi-robot systems in many scenarios. In this research, we first provide a multi-robot system to help human workers during tree fruit harvest. We present an auction-based method to coordinate a team of self-propelled bin carriers to retrieve fruit bins. Second, we propose a more general...

  • A framework for integrating systems thinking into sustainable manufacturing

    Creator:
    Zhang, Hao
    Abstract:
    Improving the understanding the relations of sustainability behaviors in manufacturing systems and actively engaging with manufacturers (especially SMEs) in sustainability efforts is key to the long-term success of U.S. industry and the natural environment. This study addresses this urgent need by establishing a systemic approach for the design of costing...

  • Sustainability assessment during early product development : the manufacturing case and the use case

    Creator:
    Seyedmahmoudighomi, Seyedhamed
    Abstract:
    The research explored in this thesis helps provide a better understanding of efforts that have been undertaken to more precisely calculate environmental impacts and human health risks, such as energy consumption, carbon footprint, and toxicity, to support environmental sustainability assessment of products. The work is comprised of two research objectives,...

  • 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...

  • Investigation of Thermal Degradation in Structural Alloys for Nuclear Power Systems

    Creator:
    Teng, Fei
    Abstract:
    The thermal degradation of structural materials is considered to be a key factor for evaluating the lifetime of current nuclear power plants. Ni-based and Fe-based alloys, such as 690, 625, 304, and 316, are widely used in nuclear industry as structural components due to the extraordinary corrosion resistance and mechanical...

  • Experiments on a low aspect ratio wing at low Reynolds numbers

    Creator:
    Morse, Daniel R.
    Abstract:
    At the start of the 21st century much of the focus of aircraft design has been turned to unmanned aerial vehicles (UAVs) which generally operate at much lower speeds in higher risk areas than manned aircraft. One subset of UAVs are Micro Air Vehicles (MAVs) which usually are no larger...

  • Empirical Characterization and Data-Driven Optimization of Water-Energy Systems

    Creator:
    Elhashimi, Mohammed A.
    Abstract:
    The accelerated development in water-energy systems calls for advanced modeling and optimization tools to improve technologies’ performance. Water desalination is a manifestation of water-energy system that is challenged by different operational constraints. The scarcity and uneven distribution of freshwater around the world makes water desalination an indispensable process to address...
