A re-examination is made of the two-dimensional interaction of a plane, timeharmonic sound wave with a rectilinear vortex of small core diameter at low Mach number. Sakov [1] and Ford and Smith [2] have independently resolved the &&in"nite forward scatter'' paradox encountered in earlier application

Interactions of two coaxial vortex rings of thin cores with and without azimuthal instability and the far field sound radiated have been studied numerically using the vortex blob method and acoustic analogy. The azimuthal instability waves of wavenumbers 1 E m E 5 are represented by weak axial and r
The pairing of two axisymmetric co-rotating vortex rings is considered as a model problem for the interaction of the large scale structures in round jets. By using direct numerical simulations of the incompressible Navier-Stokes equations, the sound radiation of the interaction has been analyzed, wi
