摘要
通过在叶尖加装V型和S型小翼探究小翼对风力机噪声的影响。利用声阵列对S参考翼型风力机加装V型和S型小翼进行风洞的声学测试。结果表明:加装V型或S型小翼使得风轮叶尖区噪声出现不同程度的降低,其中加装S型小翼降噪效果要优于V型小翼,加装S型最优小翼使得风轮噪声最大降低了6.9%。
The influence vane on noise of wind turbine was explored by adding V tip vane and S tip vane. The acoustic tests of the S reference airfoil wind turbine with V tip vane and S tip vane were carried out in wind tunnel by using acoustic array. The results show that V tip vane or S tip vane makes the noise in wind wheel blade tip decrease to different degree. The noise reducting effect of S tip vane is better than that of V tip vane. The optimal S tip vane makes the noise in wind wheel blade tip reduce by 6.9% at most.
