  • Agile Bipedal Locomotion via Hierarchical Control by Incorporating Physical Principles, Learning, and Optimization

    Creator:
    Green, Kevin
    Abstract:
    Robotic Bipedal locomotion holds the potential for efficient, robust traversal of difficult terrain. The difficulty lies in the dynamics of locomotion which complicate control and motion planning. Bipedal locomotion dynamics are dimensionally large problems, extremely nonlinear, and operate on the limits of actuator capabilities, which limit the performance of generic...

  • Passive dynamics and their influence on performance of physical interaction tasks

    Creator:
    Kemper, Kevin C., II
    Abstract:
    For robotic manipulation tasks in uncertain environments, research typically revolves around developing the best possible software control strategy. However, the passive dynamics of the mechanical system, including inertia, stiffness, damping and torque limits, often impose performance limitations that cannot be overcome with software control. Discussions about the passive dynamics are...

  • Development of a small scale scroll expander

    Creator:
    Harada, Kevin J.
    Abstract:
    The organic Rankine cycle (ORC) is a versatile approach in the utilization of waste heat in the production of electricity, clean drinking water, and cooling. The efficiency of these cycles must be maximized to make them economical. Parameters for the optimization of ORCs such as evaporator and condenser temperature have...

  • RANS and LES predictions of turbulent scalar transport in dead zones of natural streams

    Creator:
    Drost, Kevin J.
    Abstract:
    Natural stream systems contain a variety of flow geometries which contain flow separation, turbulent shear layers, and recirculation zones. This work focuses on streams with dead zones. Characterized by slower flow and recirculation, dead zones are naturally occurring cutouts in stream banks. These dead zones play an important role in...

  • Investigations into the effects of a vibrating meniscus on the characteristics of drop formation

    Creator:
    Lewis, Kevin T.
    Abstract:
    As drop-on-demand (DOD) applications continue to gain ground in desktop inkjet-printing, 3D printing, fluid mixing, and other areas the demand for higher frequency operations are beginning to push against the current physical boundaries in DOD technology. The current research is exploring the possibility of controlling drop volume and velocity at...

  • Numerical design of a high-flux microchannel solar receiver

    Creator:
    Rymal, Charles
    Abstract:
    This thesis discusses the design of several microchannel solar receiver devices for use in CSP (concentrated solar power) using CFD (computational fluid dynamics) simulations. The goal is to demonstrate that, by taking advantage of the higher heat transfer coefficienct of microchannels, solar receivers can achieve higher efficiency than current receiver...

  • Experimental Characterization of a Supercritical Carbon Dioxide Microchannel Solar Thermal Receiver

    Creator:
    L'Estrange, Thomas
    Abstract:
    Characterization of a microchannel solar thermal receiver for supercritical carbon dioxide (sCO₂) is presented. The receiver design is based on conjugate computational fluid dynamics and heat transfer simulations as well as thermo-mechanical stress analysis. Two lab scale receivers with a 2x2 cm² absorber area are fabricated and experimentally characterized -...

  • Fabrication of precipitation-hardened aluminum microchannel cooling plates for adsorption-based hydrogen storage systems

    Creator:
    Pawar, Supriya V.
    Abstract:
    The need for clean and renewable fuel such as hydrogen is driven by a growing worldwide population and increasing air pollution from fossil fuels. One of the major barriers for the use of hydrogen in automotive industry is the storage of hydrogen. Physisorption is the most promising storage technique due...

  • A microchannel-based thermal management system for hydrogen storage adsorbent beds

    Creator:
    Steigleder, Leif J.
    Abstract:
    Hydrogen has been shown to be a promising replacement for fossil fuels for use in light duty vehicles because it is a clean, renewable and plentiful resource with a high gravimetric energy density. However, in order to obtain an acceptable volumetric energy density, densification of the hydrogen is required. Adsorptive...
