Cover Story: Tidal stream turbines can harness the kinetic energy of flood and ebb currents. Avoiding interactions of turbine wakes and rotors in tidal arrays may be difficult; hence, tidal array design aims at minimizing the resulting power losses. These interactions and power losses are thoroughly analyzed, for the first time, using Navier–Stokes computational fluid dynamics of two model array flume tank experiments using up to four turbines, obtaining overall good agreement of simulations and experiments. The study’s novel finding is that flow acceleration between the wakes of two adjacent turbines can increase the recovery rate of the wake shed by an upstream centrally located turbine and thus reduce power losses of a downstream centrally located turbine. It is also found that there exists an optimal lateral spacing of the two adjacent turbines, which maximizes the power of the downstream turbine. View this paper
