摘要

Oseen vortex model is used to study the sound radiation of viscous attenuation of point vortex in free space, its spectrum is also presented. It is shown that the outer sound field has some characters including narrow frequency section and evident peak value of spectrum distribution curve. It is also pointed out that the outer sound field is related with viscous coefficient of fluid.
