Title
Multi-Fidelity Modeling and Simulation of Wave Energy Converters
Conference Dates
November 4-6, 2019
Abstract
Equations governing the response of wave energy converters (WECs) consist of partial differential equations and nonlinear boundary conditions that model the wave absorption, which is commonly used for classification of WECs, wave radiation and diffraction as required for prediction of wave energy generation by WEC farms, the converter’s response and the transduction mechanism.
To date, the modeling and simulation of WECs or WEC arrays are based on linear wave theory, which assumes irrotational flow and limits the analysis for design to small wave amplitudes. In contrast, it is desirable to operate WECs in large waves under resonance conditions that would lead to large amplitude motions for effective energy conversion. With large amplitude waves and motions or responses, the linear and irrotational flow assumptions would not be valid. In this talk, we present a review and examples of (1) physics-based multi-fidelity modeling and simulation procedures that could be performed to develop effective control and optimization strategies for different types of WECs, and (2) nonlinear phenomena that can be exploited to enhance the performance of WECs.
