  • CFD simulation of single-phase and flow boiling in confined jet impingement with in-situ vapor extraction using two kinds of multiphase models

    Creator:
    He, Xiaoliang
    Abstract:
    With continued development of the electronic industry, the demand for highly efficient heat removal solutions requires innovative cooling technologies. A computational fluid dynamic (CFD) study, including heat transfer, is performed for an axisymmetric, confined jet impingement experiencing boiling and coupled with vapor extraction. Boiling occurs at the target surface while...

  • Investigation of In-tube Non-equilibrium Condensation of Low Global Warming Potential Refrigerants

    Creator:
    Jacob, Tabeel A.
    Abstract:
    This work investigates the in-tube condensation of low global warming potential (GWP) zeotropic refrigerant mixtures R448A, R450A, R452A, R454B and R454C. These refrigerants have been proposed for a wide range of commercial heating, ventilation, air-conditioning applications, but their heat and momentum transport phenomenon were not well understood. Thus, in this...

  • Reliable Integrated Planning: Applications in Hub Network Design and Airline Ground Crew Task Assignment

    Creator:
    Barahimi, Pouya
    Abstract:
    In general, making optimal decisions is a never ending challenge that decision makers face. A comprehensive model that integrates decisions at all three levels of decision making (i.e., strategic, tactical, and operational) can help the decision maker to find solutions that best serve the organization's performance. However, as organizations expand...

  • A Text-based Simulation Framework for the Automated Simulation and Analysis of Manufacturing Assembly Systems

    Creator:
    Fields, Benjamin G.
    Abstract:
    The rapid advancement of manufacturing has led to the creation of a myriad of technologies that facilitate the analysis and simulation of manufacturing processes. These technologies have become a pivotal component in maintaining and improving processes in today’s complex manufacturing environments. Discrete Event Simulation (DES) is one such technology that...

  • Orb Web Vibrations: Modeling, Localization, and Measurement

    Creator:
    Otto, Andrew W.
    Abstract:
    The orb web is a multipurpose structure---serving as a home for its inhabitant spider, as a prey capture device, and as a physical extension of the spider’s sensing abilities. Biologists are particularly interested in the spider’s ability to locate prey trapped in its web by sensing the vibrations induced from...

  • Enabling Feasibility Assessment of Solar Thermal Energy Systems for Industrial Process Heating Applications

    Creator:
    Karki, Saroj
    Abstract:
    Existing studies on industrial heat demand have shown that more than 50% of the industrial process heat demand is in the range of low (<60 °C), medium (60-150 °C), and medium-high (<250 °C) temperatures. Most of the manufacturing industries across the world depend on combustion of carbon-based fossil fuels, either...

  • Incidental Sensor Networks for Human Mobility Detection

    Creator:
    Hoover, Sylvan
    Abstract:
    Transportation systems need to get better by moving ever more people while consuming ever fewer resources. To build better transportation systems, planners need an accurate understanding of how people exercise mobility and tools to apply that understanding to the transportation system. Such an understanding can come through the development of...

  • Hybrid Statistical and Engineering Optimization Architectures in Early Multidisciplinary Designs of Resilience and Expensive Black-box Complex Systems

    Creator:
    Biswas, Arpan
    Abstract:
    Practical engineering design problems are generally multi-disciplinary with limited budget and high risk in terms of life loss, economic resources, etc. In the early phase of such problems, selection of true efficient designs is desired while minimizing overall design cost by avoiding expensive search processes. However, the task is difficult...

    Abstract:
    Robots are being utilized in ever more complex tasks and environments to help humans with difficult or dangerous tasks. However, robotic grasping is still in its infancy and is one of the limiting factors which prevent the deployment of robots in the home and other assisted living scenarios. Traditional methods...

  • Bi-level flexible-robust optimization for energy allocation problems

    Creator:
    Biswas, Arpan
    Abstract:
    A common problem in energy allocation problems is managing the trade-off between selling surplus energy to maximize short term revenue, versus holding surplus energy to hedge against future shortfalls. For energy allocation problems, this surplus represents resource flexibility and is quantified as the surplus energy after meeting the demand. The...
