Abstract:

Recent years, in order to solve serious problems of intemperately dwindling well known fossil energy resources as coal, petroleum etc,.. and to reduce environmental impacts, the pursuit of alternative sources of energy are highly concerned all over the world, especially clean and renewable energy. Among these, the exploitation of wind and coastal currents energy to generate electricity is of particular concern. This can be attributed by the needs for the creation of technology and construction of equipment to transform those sources of energy into fresh and useful power for daily life activities of mankind. As an effective and reliable medium to support experimental researches for scientists and researchers, numerical simulation has never lost its attraction. In this paper, we introduce a methodology to investigate the flow behind a turbine generator by using the Standard k-ε model in ANSYS FLUENT. Results extracted from the research have shown a tremendously accurate model which adapts itself greatly in simulating the flow at the downstream of the turbine, particularly in the case of multiple turbines allocated in the region of interest.
