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...

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...

Evaluation of the performance of a taut-moored dual-body direct-drive waveenergy converter through numerical modeling and physical testing

Creator:

Elwood, David E.

Abstract:

With energy prices rising and increasing concern about the influence of fossil fuels on climate change, wave energy systems are on the verge of commercial implementation. These first generation wave energy converters utilize either pneumatics or hydraulics to convert the mechanical energy of waves into electricity. For the last several...
