Investigation of higher order statistics in wind turbine wakes using Large Eddy Simulations
Abstract. Large eddy simulation (LES) of the turbulent wake behind a wind turbine is employed to obtain a more complete statistical characterisation. Both one- and two-point statistics are therefore considered, including velocity increments. The downstream evolution of the wake size is determined by different statistical quantities, including the intermittency ring. Higher-order statistics show that the wake expands beyond the region commonly defined using the mean wind speed. Regarding the numerical simulations, a new method is introduced to reduce the computational cost of high-resolution wake simulations.
