Descritivo da Vaga:
Tipo de Atividade: Although tidal stream power generation is still in its infancy, the IEA projects a significant investment in this technology in the coming decades. However, some researchers are concerned about the current development of horizontal-axis turbines that sit on the sea floor, where the flow field is weakened and disturbed by the boundary layer. For wind turbine farms, each machine creates a turbulent wake, which affects downstream turbine generators. This project will consider a circular cylinder in cross-flow, with a rectangular slot orifice embedded in its surface from which a synthetic jet can be generated. An initial analysis will use transient CFD simulations to study the effect of a synthetic jet emanating from the surface of a cylinder in cross-flow on the behaviour of the wake flow in general, and the instantaneous lift and drag coefficient in particular. Specific attention will go to determining the mechanisms of drag reduction, looking for correlations between the drag force and characteristics of the near wake and far wake. Depending on the preferences and background of the student, the project can be involve experimental or computational work, or a combination of both. CFD simulations can be carried out, building on earlier work. Additionally, validation experiments can be carried out using a water tunnel test facility equipped with a lift and drag force sensor, and capable of performing time-resolved particle image velocimetry (PIV) measurements. A strong background in fluid mechanics and aptitude for CFD and/or experimental work is required. (2) Target outcomes The student will take part in this research project, with a goal of preparing a working paper, which could later be submitted to a conference or journal, depending on progress made during the traineeship project. The student will gain valuable research skills on active flow control and advanced fluid mechanics. For experimental work, the student will gain practical hands-on experience in using and modifying a water tunnel test facility and its associated instrumentation (e.g., lift and drag sensor, flow velocity measurements, ultrasonic flow meters, pumps and variable speed drives, DC motor speed controllers and pressure sensors). For computational work, the student will gain experience with modelling transient turbulent flows using a commercial CFD package such as Ansys Fluent. (3) Supervision The student will become a member of an active research team, working alongside several PhD students and postdoctoral researchers, and supported by the PI. An experimental officer and a team of design engineers are available in the Department to assist the student with practical aspects of lab work. Laser safety training will be provided by Trinity College if the student will be conducting lab work with laser-based instrumentation, such as particle image velocimetry. The PI will supervise the student and a senior PhD student will be assigned to the student on a mentorship basis.
