Project Description

The hydrodynamics of wave breaking are important in the context of breaking wave forces on offshore and coastal structures. They are also important in the context of coastal sand transport in shallow water because of the impact of breaking on the near-bed turbulence and stresses, and on sediment entrainment, suspension and advection. The PhD project will study breaking wave hydro- and sediment dynamics based on experiments conducted in the 20m-long random wave flume at the University of Aberdeen. The research will involve two main experimental programmes. In the first, a range of breaking wave conditions will be generated over a fixed (immobile) bed and the detailed water particle velocities will be measured using laser Doppler and particle image velocimetry (PIV), with particular focus on the bottom boundary layer hydrodynamics, turbulence and shear stresses. In the second, experiments will be conducted for a range of breaking wave conditions over a mobile bed to study subsurface pressure, entrainment and suspension processes.

The successful candidate should have, or expect to have an Honours Degree at 2.1 or above (or equivalent) in civil or mechanical engineering; other relevant physical science. An excellent first degree in engineering, or related discipline that includes fluid mechanics, will provide the essential knowledge.

Prior knowledge of the following would be beneficial but is not essential: sea wave mechanics; laboratory measurements in fluid mechanics.

Funding Notes

There is no funding attached to this project, it is for self-funded students only.
