Development of next-generation marine renewable energy technologies

The Section of Marine Environment and Energy Engineering Section is dedicated to developing new technologies for utilization of marine renewable energies including ocean wind, tidal current, ocean current and surface wave; and to studying the environmental impact of these renewable energy developments. Main ongoing research projects are as follows.

R&D of an ocean floating platform of low cost and high performance
R&D of highly efficient tidal and ocean current turbines
Conceptual study of a floating tower for offshore overhead power transmission system
Development of novel CFD methods for safety assessment of floating offshore wind turbines and optimization arrangement study of a tidal current farm

Development of high-fidelity CFD solver for complex multiphase flows

We are also dedicated to the development of high fidelity multiphase simulation tools with extreme scalability. The developed tools target challenging flow phenomena such as complicated fluid-structure interaction problems using the state of the art CFD technologies. Currently, the following three development tracks are considered.

Develop a new CFD solver for the simulation of multi-phase fluid flow based on the Flux Reconstruction (FR) arbitrary-order method
Utilize the power of machine learning to improve conventional CFD method and develop new numerical schemes
Towards extreme high-resolution CFD simulation by using particle method, Lattice Boltzmann method, etc.
