A recently proposed analytical wake model for a horizontal axis utility scale wind turbine is revisited, and revised and improved. The model is based upon conservation of momentum in the context of actuator disc theory, and the assumption of a distribution of the double-Gaussian type for the velocity deficit in the wake. The model is developed and improved and reveals characteristics of the wind turbine wake velocity deficit for the full wake, including the near-wake to within close proximity of the wind turbine rotor. Full 2-dimensional model fitting to lidar wake measurement data obtained from a 5 MW utility scale wind turbine is carried out for the full range of inflow wind velocities of primary interest. Such a full wind turbine wake model has the potential to facilitate analytic calculations within the wind turbine wake region, and the potential to improve understanding of wind turbine aerodynamics.

对最近提出的用于水平轴公用规模风力涡轮机的分析尾流模型进行了重新研究，修订和改进。该模型基于执行器圆盘理论中的动量守恒，并基于尾流中的速度赤字的双高斯型分布假设。该模型得到了发展和改进，揭示了整个尾流的风力涡轮机尾流速度不足的特征，包括在风力涡轮机转子附近的近尾流。针对主要关注的整个进风速度，对从5 MW公用事业规模的风力涡轮机获得的激光雷达尾流测量数据进行了全二维模型拟合。这样的完整风力涡轮机尾流模型具有促进风力涡轮机尾流区域内的分析计算的潜力，
