| Abstract: | 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. |
