Analysis of the near wake of a horizontal axis tidal turbine
MEng in Civil Engineering from QUB.
Work includes velocity measurement within the flow field of a horizontal axis tidal turbine model by particle image velocimetry (PIV). These measurements are analysed to aid the understanding of near wake processes and to provide datasets of high quality and resolution for the validation of numerical models which represent a second line of research. Systematic development of Reynolds-Averaged Navier Stokes computational fluid dynamics (RANS-CFD) models is underway using the commercial package Ansys-CFX. Once validated, these models will be used to provide near wake predictions for larger scale devices which prohibit the collection of such high quality data.
