Abstract

A Gaussian shape three-dimensional wake model（3DG-k） is proposed considering the wind shear effect. The model defines the wake radius r_w equal to twice the Gaussian characteristic parameter σ of the physical wake boundary to describe the evolution law of the wake boundary after the wind turbine. The 3DG-k model, Jensen model, three-dimensional Gaussian model （3DG） and three-dimensional elliptical Gaussian model （3DEG） are compared and analyzed by GH wind tunnel experiment data, actual measurement data from Nibe wind farm and large eddy simulation data from Vestas V80-2 MW wind turbine. The results show that the 3DG-k model shows the best prediction accuracy in all three cases and is more suitable for practical engineering applications.

Key words
