Wake interactions of two tandem floating offshore wind turbines: CFD analysis using actuator disc model

Floating offshore wind turbines (FOWTs) have received great attention for deep water energy harvesting. So far, research has been focused on a single floating rotor. However, final deployment of FOWT farms, interactions multiple FOWTs and potential impacts the motion power performance wake rotors need to be investigated. In this study, we employ CFD coupled with an Actuator Disc model analyze two tandem scenario, where upstream rotor is prescribed surge downstream fixed influenced by variations in incoming flow created oscillating surging We will investigate three different amplitudes fluctuations as well their interactions. The results show light increase mean coefficient both case, compared against case no motion. standard deviation transient CP linearly scales amplitude, while such impact very limited. Surging found enhance mixing wake, which therefore, accelerates recovery This finding suggests prospects into redesigning farm layout FOWTs, aiming more compact arrangements.
