Description

 The report reviews the literature on the study of the interaction of several coherent vortex structures and their generation of the sound field. The interaction of several coherent vortex structures in the absence boundaries is considered within the moment model (MZS-model) of the first and second orders, the sound field as a result of the vortex interaction is described within the acoustic analogy of Lighthill in the Powell formulation. The velocity field inside the vortex spots (Kirchhoff vortices) and vortex deformation in the velocity field of distant vortices are determined.
