摘要：

In an elliptic jet forced at low-frequency range, the vortex merging is suppressed before the end of the potential core. The coherent structure switches its axis due to the self-induction of the asymmetric distribution of vorticity. At higher forcing frequency, the vortex merging is observed. The stretching or contraction around the downstream vortex produces unequal induction on parts of the upstream vortex. Thus, large azimuthal distortion occurred during vortex merging.
