Abstract
A scaled-model of an HATCT (Horizontal Axis Tidal Current Turbine) was tested in the CNR-INSEAN Circulating Water Channel. Two different analyses were performed during the experiments: preliminary investigation of the performances of the turbine in different working conditions and PIV (Particle Image Velocimetry) measurements in the near wake along a longitudinal plane. Velocity measurements are performed phase-locked to the rotor, in order to resolve the blade wake structure at different working regimes. Indeed, the flow field knowledge (axial, radial) allows to evaluate the behavior of the slipstream expansion in the longitudinal evolution.| File | Dimensione | Formato | |
