抄録

Vortex ring impacting a solid boundary in a rotating fluid has been visualized by dye to know the effect of rotation to its circumferential instability. Decrease in centerline ejection velocity has been observed due to the existence of background rotation. However, the number of waves of vortex ring in rotating fluid which are generated when it impacts a solid wall was almost same as that of without any background rotation. This result shows the number of waves of vortex ring which can be estimated by the initial condition is reproduced when it impacts a solid boundary even though the effect of rotation exists in the flow.
