Development of a test protocol for particle tracking velocimetry of turbine wakes in a towing tank

This thesis focuses on developing and testing a model turbine for floating offshore wind, exploring performance in MarinLab of HVL University of Bergen. Analysis of the flow behind the turbine with changing the position of the turbine, camera and light help to achieve a good comparable results. Thrust coefficients align with expectations, while power coefficients show notable deviations attributed to Reynolds number effects. Oscillating structural movements impact turbine performance, with standard deviations indicating speed variations. The study recommends further exploration of Reynolds number effects with turbulence intensity, varied amount of particles.
