摘要
基于涡云模型研究涡和翼型的强相互作用，重点模拟主涡在贴近翼型表面经过时涡变形对声偶极子强度的影响，并与单点涡模型的研究结果进行了比较。
Based on the model of vortex cloud, the vortex-airfoil strong interaction is studied. The distortion of the main vortex is simulated while it passes close up to an airf0il. The effects of the vortex distortion on the strength of the acoustic source 0f dipo1e type are investigated. The results are compared with the earlier results based on the model of single point vortex.
