This talk will review recent work in our group on efficient methods for predicting the complex interaction between highly nonlinear ocean waves and fixed or floating maritime structures. Of particular interest are renewable ocean energy devices such as wind turbines and wave energy extraction devices. Ambitious targets have been set by all EU countries for significantly increasing the proportion of energy obtained from renewable sources. Much of this expansion is expected to occur offshore. Due to installation and transmission costs which increase dramatically with distance from land, new parks will tend to be as close to shore as possible. Wave fields in such near-shore, intermediate depth regions can be especially complex due to nonlinear wave-wave interaction, refraction from the sea floor and diffraction from the coastline and coastal structures. For effective design of offshore energy parks, a good description of the expected wave climate is required, as are good models for the interaction between the waves and the structures. I will describe two numerical models under development in our group for providing such predictions. The basic strategy is to ignore viscous effects, and employ high order numerical schemes combined with effective preconditioned iterative strategies, to achieve high accuracy solutions with coarse resolution and thus high efficiency.
Biography
Professor Bingham obtained his PhD entitled "Simulating ship motions in the time domain" at Massachusetts Institute of Technology in 1994, following MS and BS degrees from Stevens Institute of Technology and Cornell University. He has held research positions at International Research Centre for Computational Hydrodynamics, Hørsholm, Denmark as well as MIT. He been Associate Professor of Computational Fluid Dynamics at Technical University of Denmark, Lyngby since 2004, prior to which he has Associate Research Professor at the same institution, setting up the Computational Hydrodynamics Group. His publications include over 20 journal papers and 35 conference papers.
