用CFD方法模拟计算风力机尾流的研究

Study on the simulation of wind turbine wake by CFD method

根据计算流体力学的原理和数值计算的方法,将研究区域划分为非结构网格,通过设置合理的边界条件,采用湍流模型模拟了不同间距的风力机尾流流场,对不同尾流流场的压力、速度和涡量的分布进行了分析,从而确定了在风力强度及风向相同的情况下,不同风力机间距的尾流特点。

Based on the principles of hydrodynamics and numerical computation,the study area will be classified as non-structured grids,by setting a reasonable boundary conditions,the turbulence model is used to simulate the wind turbine wake field in different spacing,The analysis has been carried out on the different wake flow field pressure,the velocity and the vorticity,in order to determine the characteristics of the wakes in different spacing,under the same wind strength and in the same direction.
