Computational modelling of flexible wave energy converters

Whilst solar and wind energies have become dominant options in the renewable energy sector, wave energy is yet to become truly competitive. For wave energy to attract renewable energy marks and becomes truly competitive, new designs and concepts of wave energy converters that are cost-effective and energy-efficient are essential. Recent advances in multifunctional polymeric composites over the past couple of decades have led to the exploration of alternative designs for wave energy converters (WECs) that involve flexible structures or a combination of rigid and flexible structures for wave energy harvesting.

The challenges in simulating flexible WECs are multifold: (i) interaction of thin flexible lightweight structures with wave currents, (ii) large structural deformations, (iii) coupled viscoelasticity at finite strains, (iv) multiphase flows and (v) large-scale models. Towards addressing challenges in simulating wave-structure interaction problems with flexible lightweight structures, this project will develop advanced simulation platforms with the capabilities to conduct computationally efficient high-fidelity coupled simulations of flexible WECs. This project includes collaborations with other universities in the UK.

The project consists of the following major activities:

• Couple FE framework for flexible solids with CFD solvers.
• Validate the simulation framework.
• Explore different designs for flexible WECs.
• Disseminate research outputs in journals and at conferences.

Perspective applicants are encouraged to contact the Supervisor before submitting their applications. Applications should make it clear the project you are applying for and the name of the supervisors
