摘要
利用CFD软件对所取多个翼型截面为基准下的风力机桨叶和风轮覆冰进行数值模拟,在针对三维风力机桨叶结冰时,采取截取多个翼型进行二维覆冰模拟得出覆冰冰形,从二维覆冰的形状和覆冰的覆盖区域以及覆冰量的规律去判断整个桨叶覆冰的属性,且在之后针对风力机桨叶覆冰前后性能进行对比分析。研究结果对风力机桨叶的覆冰机理和风力机运行控制具有一定意义,且为风力机桨叶覆冰的实验研究提供了理论基础和对比数据。
The main objective of this paper is to model the icing accretion process on a horizontal-axis wind turbine (HAWT) blade and rotor operating under icing conditions with the help of CFD. Aim at icing on wind turbine blade in three-dimensional, several airfoil were taken to simulate the freezing ice shape in two-dimensional. The whole blade icing attribute was judged by icing shape, the icing covering area and the icing regular pattern in two- dimensional, and then the performance of wind turbine blade under icing before and after was comparative
