摘要：

A Gaussian shape three-dimensional wake model （3DG-k）is proposed considering the wind shear effect. The model defines the wake radius rw equal to twice the Gaussian characteristic parameter σ and establishes a link with the expansion coefficient k 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. © 2023 Science Press. All rights reserved.
