  • Hydrodynamic contact/impact modeling and application to ocean engineering problems

    Creator:
    Challa, Ravi
    Abstract:
    Fluid-structure interaction (FSI) is a very interesting and challenging multi-disciplinary field involving interaction of a movable or deformable structure with an internal or surrounding fluid flow. FSI has several practical engineering applications such as the determination of the hydrodynamic forces on a structure or the dynamics of motion of bodies...

  • Numerical modeling of full-coupled fluid-structure interaction

    Creator:
    Yuk, Dongjun
    Abstract:
    A numerical model for the simulation of fully-coupled fluid-structure interaction is developed in this study. In modeling the fluid, the Reynolds Averaged Navier-Stokes equations are solved for an incompressible viscous fluid field and a k-ε model is employed for turbulence computations. Hydrodynamic forces obtained by the integration of the fluid...

  • Fluid-structure interaction analysis with the particle finite element method

    Creator:
    Zhu, Minjie
    Abstract:
    To facilitate the evaluation and design of structures subjected to fluid loading, a study of fluid-structure interaction (FSI) using the particle finite element method (PFEM) is presented to approximate the responses and sensitivities of structures which interact with fluid. A wide range of structural types are permissible by making no...

  • Numerical studies of mesoscale eddies using quasigeostrophic and primitive equation ocean models

    Creator:
    Batteen, Mary L.
    Abstract:
    The dynamical role of mesoscale eddies in the ocean general circulation is investigated using eddy-resolving quasigeostrophic (QG) and primitive equation (FE) models which are parametrically identical. The results of both QG and FE numerical experiments in mid-latitude, rectangular ocean basins are systematically intercompared and extensively analyzed in terms of basic...

  • Simple models for the structure and dynamics of polyatomic fluids

    Creator:
    James, Corinne Patricia
    Abstract:
    Three areas of liquid state theory are considered. First, Monte Carlo computer simulation of a two-dimensional hard disk fluid with an imbedded ellipse was undertaken to determine how a non-spherical molecule affects intermolecular ordering. The elliptical molecule (with axial ratios of 2, 5 and 10) altered the isotropic distribution of...

  • Surface wind modification near mid-latitude ocean fronts : observational and dynamical analysis

    Creator:
    O'Neill, Larry W.
    Abstract:
    Interactions between surface winds and meanders in mid-latitude sea surface temperature (SST) fronts with horizontal length scales of 100-1000 km are investigated from satellite observations and numerical simulations. Observations from the Sea- Winds scatterometer on the QuikSCAT satellite show that the magnitude, direction, curl, and divergence of the surface wind...

  • A study of El Niño/southern oscillation : numerical experiments and data analysis

    Creator:
    Ahn, Joong Bae
    Abstract:
    For the purpose of investigating the fundamental nature of the interannual oscillation observed in the tropical Pacific in conjunction with El Nino/Southern Oscillation (ENSO), the Comprehensive Ocean Atmosphere Data Set was analyzed. Based upon this analysis, an "intermediate" tropical atmosphere-ocean coupled model was developed. For reason of their particular importance...

  • Hybrid Multiscale Methods with Applications to Semiconductors, Porous Media, and Materials Science

    Creator:
    Costa, Timothy B.
    Abstract:
    In this work we consider two multiscale applications with tremendous computational complexity at the lower scale. First, we examine a model for charge transport in semicon- ductor structures with heterojunction interfaces. Due to the complex physical phenomena at the interface, the model at the design scale is unable to adequately...

  • Computational methods for protein-protein interface prediction

    Creator:
    Tribelhorn, Benjamin
    Abstract:
    Protein-protein interactions underlie all biological processes and are a field of study that has wide implications throughout many other fields including medicine, genetics, biology, and ecology. Proteins are the building blocks and primary actors of life. They work together to accomplish virtually every task within a cell, including, metabolism, signal...
