摘要
针对不同弦长下的小型H型垂直轴风轮模型,建立风轮外流场CFD(Computational Fluid Dynamic)模型,采用移动网格技术,选用RNG两方程湍流模型和基于压力的隐式Couple算法进行瞬态计算,获得风轮气动性能曲线,进而分析叶片弦长对小型H型垂直轴风力机风轮气动性能的影响。
Aiming at the small H-vertical Axis Wind Turbine with different length of blades chord, construct a CFD model for outside flowfield. Moving mesh technique is used to construct the model,the RNG two equation turbulent models and the implicit Couple arithmetic based on pressure is selected to solve the transient equation. Curves for the aerodynamics performance of the wind turbine are gat from the result. With the curves how the length of the blade chord affecting the aerodynamic performance of the small H-vertical Axis Wind Turbine is analyzed.
