Abstract

As a former PhD candidate, I would like to take this opportunity to express my thanks to all teachers and colleagues for their transferring knowledge and supervisions when I studied in Tsinghua University, and their kind helps and supports after I graduated.

This seminar talk includes two parts: one involves the developments of numerical methods for linear and nonlinear fluid-structure interaction dynamics with applications in engineering, and another one is for designs of wave energy harvesting devices based on integrated convertor-oscillator-fluid interaction dynamical analysis.

The main points and advances of numerical methods for f-s interaction dynamics will be given, which includes: mixed FEA displacement-pressure model, mixed displacement – BEM model, Mixed FEA-FD model and Mixed-SPM model to deal with linear and nonlinear problems involving breaking waves and f-s separations. Several engineering problems as examples are presented.

Linear and nonlinear oscillators, aerofoils are used to design the wave / fluid energy harvesting devices based on their characteristic behaviours. The resonance of linear system and the flutter of nonlinear system that are to be avoided in the dynamic designs are now tried to be used to harvest fluid energy. The integrated system is an interdisciplinary one concerning the mechanical-electrical coupling and the fluid-structure coupling.
