Introduction of the Research Group

The Wave Energy Conversion Research Group work with offshore renewable energy and harnessing the power of ocean waves to produce electricity and desalinated water. They  have a strong background in Hydrodynamics and Computational Fluid Dynamics and have worked extensively on the development of numerical wave tanks which are digital twin for the ocean environment and this enables researchers to simulate, evaluate and optimize  offshore renewable energy devices. Additionally, the Research Group applies applies the expertise in the field of nonlinear dynamics at the university to applications within wave energy conversion such as the stability of floating bodies and the phenomenon of parametric resonance.
