  • Investigating Timescales of Resurgence at Large Calderas: Post-74 ka Activity at Toba Caldera, Sumatra, Indonesia

    Creator:
    Mucek, Adonara E.
    Abstract:
    The Toba Caldera Complex is the youngest resurgent caldera in the last 100 kyrs, formed from four overlapping eruptions starting 1.2 Myrs ago. The last caldera-forming eruption, the Youngest Toba Tuff eruption, occurred ~74 kyrs ago, emitting 2800 km3 of ash and pumice into the atmosphere and forming the caldera...

  • Investigating climate feedbacks across forcing magnitudes and time scales using the radiative kernel technique

    Creator:
    Jonko, Alexandra
    Abstract:
    Radiative feedbacks associated with changes in water vapor, temperature, surface albedo and clouds remain a major source of uncertainty in our understanding of climate's response to anthropogenic forcing. In this dissertation climate model data is used to investigate variations in feedbacks that result from changing CO₂ forcing and the time...

  • DNS study of Particle-bed-Turbulence Interactions in Oscillatory Flows

    Creator:
    Ghodke, Chaitanya Deepak
    Abstract:
    Turbulent flows over rough surfaces are encountered in many engineering and geophysical applications. Flows of this nature, due to their increasing technological interests, have been a subject of rigorous investigation in recent years. Of the particular interest to the oceanographic community is the study of turbulent oscillatory flow over rough...

  • Dynamical System Scaling of Fuel Performance During Reactivity Insertion Accidents

    Creator:
    Dueñas, Alexander M.
    Abstract:
    Fuel qualification timelines for new fuel technology under ideal conditions can take between 20-25 years to be fully qualified from initial concept to deployment as full fuel assemblies. To reduce the timeline and costs, new separate-effects test and integral-effects test experiments, advanced instrumentation, and advanced modeling and simulation tools are...

  • Vertical Coastal Trapped Wave Propagation Produced by a Subsurface Ridge

    Creator:
    Dhage, Laxmikant
    Abstract:
    The vertical propagation of Coastal Trapped Waves (CTWs) due to subsurface ridges is explored with the help of linear numerical and analytical models. Results show that submerged ridges projecting from the shoreline can scatter a horizontally propagating single baroclinic mode Kelvin wave into both upward and downward propagating Kelvin wave...

  • On the Euler-Lagrange Modeling of Particle-laden Turbulent Flows

    Creator:
    Pakseresht, Pedram
    Abstract:
    Particle-laden turbulent flows, wherein a large number of small size particles are dispersed in a fluid, are widely encountered in environmental and industrial applications. Understanding their underlying physics, making predictions without performing expensive experiments, and ultimately optimizing the systems carrying such flows, require accurate and robust modelling tools. The Euler-Lagrange...

  • Predicting mechanical instability of a cylindrical plate under axial flow conditions

    Creator:
    Marcum, Wade R.
    Abstract:
    Five U.S. high performance research reactors (HPRRs) are currently part of an international nonproliferation program with the objective of ultimately converting their highly enriched uranium (HEU) fuel to a new high density, low enriched uranium (LEU) fuel while still maintaining their reactor kinetic and thermal hydraulic performance. A uranium-molybdenum (U-Mo)...

  • 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)...

  • Numerical simulation of cavitating bubble-laden turbulent flows

    Creator:
    Shams Sobhani, Ehsan
    Abstract:
    Many engineering devices and propulsion systems suffer from undesirable effects of cavitation; such as degradation in the efficiency of pumps and turbines, generation of noise and vibration on ship propeller, increased drag and erosion of propeller blade, etc. In spite of decades of research on this problem, detailed study of...
