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 present work extends the study of interactions of two coaxial vortex rings of thin cores with azimuthal instability to wavenumber range 6)m)11. Unstable modes are found at 6)m)10. Stable mode is found only at m"11. The present range of unstable wavenumbers m"1, 2, 5 to 10 of the two interacting
