Abstract
The interaction between vortex rings and walls widely exists in natural phenomena and engineering practices. In this paper, we experimentally explore synthetic jet vortex rings impinging on a spherical wall. The impingement behavior is revealed in detail by vortex ring evolution and trajectories. An important observation is that driven by the curve, the strength of the induced vortex ring increases with the decrease in the sphere diameter.
