| Abstract: | The axial fans with skewed blades widely used in engineering practices are studied, and during the study, the blade is divided into N elementary sections in radial direction. The vortex shedding noise model for the fan and the model for the blade tail-edge vortex noise induced by the interaction between the air flow and the k th section have been developed. The correctness of the models is verified by experimental results. The relationship between the structural parameters of the blade and the vortex shedding noise is discussed. The axial fan of low noise can be designed and optimized using the results obtained. |
