  • GPU-Based Fluid-Structure Interaction using Immersed Boundary Methods

    Creator:
    Minar, Christopher
    Abstract:
    Engineering applications often require fast, accurate solutions of fluid flow around freely moving bodies. The massive parallelism enabled by graphics processing unit (GPU) architecture enables high performance, offering a promising alternative to traditional solver acceleration via multicore central processing units (CPU). However, fully harnessing GPU parallelism requires specialized algorithms and...

  • An approach to reduced-order modeling and feedback control for wave energy converters

    Creator:
    Shoori J., Hesam E.
    Abstract:
    Wave energy holds great promise to be part of the alternative energy portfolio that will provide independence from fossil fuels. As wave energy converter (WEC) technologies mature, designing effective control strategies to extract maximum energy, extend device life, coordinate WEC operation within an array, or mitigate negative impacts of a...

  • Hydroelastic modeling of a wave energy converter using the arbitrary Lagrangian-Eulerian finite element method in LS-DYNA

    Creator:
    Meicke, Stephen A.
    Abstract:
    This thesis investigates the applicability of the finite element method to model wave energy converter (WEC) hydroelasticity using LS-DYNA. The proposed methodology uses the Arbitrary Lagrangian-Eulerian formulation to model Fluid-Structure Interaction (FSI) between the WEC and the fluid elements. This formulation allows for time-domain modeling of higher order effects such...

  • A study of the characteristics of oscillatory surface instabilities leading to droplet formation

    Creator:
    Daniels, Brian J.
    Abstract:
    The characteristics of the free surface in an orifice driven by a periodic forcing function have been studied both theoretically and experimentally. In the theoretical study, two wall boundary condition cases were examined: 1) the radial velocity at the wall of the orifice is zero; and 2) the axial velocity...
