Abstract | A numerical study of interaction of two coaxial vortex rings with initial weak perturbations is reported. The vortex rings are modelled by thin vortex filaments and their evolution is solved by means of three-dimensional vortex blob method. Numerical results reveal the growth of the weak perturbations and hindrance of the repeated leapfrogging, causing the merging of the two vortices. The acoustic radiation before the vortex merging is also presented. |
