Sustainable Energy Research Project for Dong-Sheng Jeng

22 November 2006

The School is pleased to announce that Dr Dong-Sheng Jeng has been awarded over $200000 as part of the University Sustainable Energy Research Scheme for his project 'Innovative approaches for wind, waves, offshore wind farm and seabed interaction: a coupled model'.

Renewable energies have considerable potential and could theoretically provide a nearly unlimited supply of relatively clean and mostly local energy. In general, renewable energy supply has been growing strongly; the annual growth for wind energy, for example, has been around 30% recently, albeit from a very low base. Onshore wind energy has grown enormously over the last decade to the point where it generates more than 10% of all electricity in certain regions. However, due to the limitation of land-use for onshore wind farms, offshore wind energy promises to become an important source of energy in the near future: it is expected that by the end of this decade, wind parks with a total capacity of thousands of megawatts will be installed in European seas.

Although numerous offshore wind farms have been constructed in EU and USA, no such a facility is available in Australia. Development of green (renewable) energy has been recongised as an alternative and favor option in Australia. It is expected that offshore wind energy will be an important renewable energy in Australia in the next decade. Thus, it is desired to develop the technique of Offshore Wind Farms (OWF) now.

The innovation of this project lies in the extension of the existing models for OWF from individual aspects to a coupling model. Most existing models have been limited to either fluid-soil or fluid-structure or soil-structure interaction. Thus, the major objective of this project is to integrate them into one model, which allows engineers to have a better understanding of the full process of the flow, soil and structural problem of offshore wind farms.

In this project, six (6) new PhD students and a research fellow will involve in the development of each component and coupling process. This project is fully supported by USyd Sustainable Energy Research (SER) Scheme over 2007-2009.
