Research project: Investigation of Wave Impact on Permeable Structures for Coastal Defences

Currently Active: 
Yes

The understanding of wave impact dynamics on solid and/or permeable structures for coastal defences is of great importance; as they can cause many casualties and huge economic damage. Simulation of the dynamics of the flow prior to, at and after impact presents a great challenge in CFD. In this work, new techniques will be developed for free surface flow simulations, analyses of forces of impact, and the integrity of structure responses to sea defences using an information system environment context.

Project Overview

There is scientific interest in understanding the underlying wave impact dynamics on solid and/or permeable structures for coastal defences. The accurate and validated simulation of the dynamics of the flow prior to, at and after impact has been an outstanding and challenging numerical problem in CFD (Sabeur et al 1995, 1998, Tan et al 2009, and Godderidge et al 2011). When more advanced numerical modelling of free surface flow, including air entrapment processes is achieved, greater insight into the trends of pulse-like forces involved at impact with solid and/or porous material will enable the understanding of the mechanical stability and integrity of sea defences while improving their future design.

Furthermore, the deployment of advanced numerical models for simulating such phenomena will need to be made web-accessible as information systems to a wider community of civil and coastal engineers in order to achieve collaborative integrated design of structural defences by UK Enterprise. The projected research is on free surface flow simulations, flow visualisation, analyses of forces of impact, and the integrity of structure responses to sea defences using an information system environment context.

This proposed cross-disciplinary research will be conducted under a joint collaboration from the Faculty of Physical and Applied Sciences and the Faculty of Engineering and Environment of the University of Southampton. It offers a unique opportunity for the candidate to interact with researchers in computational fluid dynamics, information systems design and web enablement from the designated Faculties.
