Fluids modelling to enhance wind turbine performance
Computational fluid dynamics (CFD) is an indispensable tool for optimising wind turbine performance.
Our wind turbine CFD simulation demonstrates how we leverage advanced numerical approaches to analyse and enhance the efficiency of turbine designs.
Assessing the impact of extreme waves on wave energy converters
Wave energy converters (WECs) are devices designed to harness the huge potential renewable energy source of ocean waves. In contrast to typical offshore structures these devices are generally designed to be in-tune with waves and hence undergo large motions due to wave forces.
It is of significant importance to accurately estimate not only their performance in moderate sea conditions but also their responses in extreme waves. CFD provide an indispensable tool to model wave interaction with WECs in range of conditions.

Machine learning to improve ship motions
To develop a superior motion control system for a high speed ship, we built a model of the highly dynamic physical system of the ship motions from observation data using state-of-art machine learning algorithms.
The machine learning models are used with real-time optimisation algorithms to estimate and enhance system response to external disturbances and control inputs. Various sources of data are used, such as sensors and data from external APIs, for both model building and in the deployed solution.
