SES-77-178 PhD Studentship: Environmental impact of marine renewable and ship generated underwater noise

There is an increasing interest in the underwater noise generated by shipping and by the installation of offshore marine renewable energy systems, such as wave and tidal devices, and the resulting impact that they may have on marine life.

As part of an on-going project to help quantify the likely levels of underwater noise this research will involve the development of computationally efficient techniques for predicting sound sources due to turbines/propellers and their likely propagation in shallow (littoral) waters including the influence of seabed composition and wave effects.  The application of computational fluid dynamics techniques based on large eddy simulation (LES) and variants thereof allows the influence of hub, blade tip, tip gap and trailing edge geometry to be evaluated for attached and bluff body flows.  One area that merits further investigation is the impact of structural coupling for the next generation of adaptive blades based on composite construction.

If you wish to discuss any details of the project informally, please contact Professor Stephen Turnock (srt@soton.ac.uk ) Tel: +44 (0) 2380 592488. or Professor Victor Humphrey (vh@isvr.soton.ac.uk) Tel: ++ (0)2380 594957
