摘要
采用二维不可压缩N-S方程和SSTk-ω湍流模型研究了风力机翼型DU 95-W-180在粗糙表面时的空气动力学性能,在整个翼型表面均匀分布不同高度的粗糙带时,得到了该翼型的升力和阻力特性曲线,以及最敏感的粗糙度;同时,研究了在翼型压力面和吸力面的不同位置布置粗糙带时,粗糙带位置对翼型的升力和阻力特性的影响,通过分析得到了该翼型对粗糙带的最敏感位置,并进一步分析了翼型两个敏感位置的粗糙度对翼型升力特性、阻力特性和升阻比的影响。
The two-dimensional incompressible N-S equations and the SST k-ω turbulence model were used to study the aerodynamic performance of a wind turbine airfoil under rough surface conditions.The DU 95-W-180 airfoil that is widely used in wind turbines was chosen as the object.The studies were mainly done as described： the lift coefficient and the drag coefficient of the airfoil under different roughness heights on full surface and different roughness tape locations were computed,the trend of the lift coefficient and the drag coefficient with the roughness height and the roughness tape location were analyzed,the critical value of the roughness height and the roughness tape location,the trends of the lift coefficient,the drag coefficient and the ratio of lift coefficient and drag coefficient with the roughness height at the critical locations were also analyzed and the results were gained.
