Abstract

The limited space available for wind energy projects highlights the importance of improving the efficiency of wind farms, like the exploitation of turbulent wakes. In this work, we analyze the available energy associated with the turbulent wakes generated by offshore wind turbines at various downstream distances using a computational fluid dynamics (CFD) program (Autodesk). Classical wind conditions for offshore wind farms are established for the probability distribution of wind speed, applying the Weibull distribution, and for the angular distribution of wind direction, using the Von Mises distribution. This study allows determining the amount of recovered energy by the drag turbine at different downstream distances, resulting in an efficiency increase up to 11.59% for a drag turbine with a diameter of 80 m and an estimated power coefficient of Cp=0.15 located at a downstream distance of 2.5 times the diameter of the conventional wind turbine.

Keywords: Turbulent fluid, wakes, CFD technique, modelling and simulation, offshore wind turbine, efficiency improvement
