pre332 - Modelling and Control of Ocean Energy Systems (Complete module description)

At the completion of this module, the student will:
- be familiar with the linear hydrodynamic theory of wave energy systems
- be familiar with the hydrodynamic theory of marine current turbines (BEM)
- be introduced to advanced numerical hydrodynamic modelling of wave and current systems and control simulation
- be familiar with experimental testing and monitoring of OE systems
- acquire basic knowledge of other forms of ocean energy and their systems as OTEC and salinity gradients.

- Wave energy systems: Types of wave energy converters. Linear wave structure interactions. Frequency domain analysis. Hydrodynamic coefficients and their computation. Time domain analysis. Phase control. Arrays. Model testing techniques. Marine current turbines. Types of marine current turbines.
