Wind turbine wakes negatively affect downwind turbines in wind farms reducing their global efficiency. The reduction of wake-turbine interactions by actuating control on yaw angles and induction factors is an active area of research. In this study, the capability of spanwise-periodic rows of wind turbines with tilted rotors to reduce negative wake-turbine interactions is investigated through large-eddy simulations. It is shown that, by means of rotor tilt, it is possible to replace turbine far wakes
