Vortex ring interactions created by a pulsed jet
Vortex ring interactions created by a pulsating annular jet
Padron, A. Santiago; Baker, John
This video shows the interaction between vortex rings generated by a pulsating low-speed annular jet. The jet issued into a quiescent water reservoir and was visualized by means of dye. The blocking ratio of the annular jet was fixed at 0.7. The Reynolds number of the flow was 155 and the frequency was 0.5Hz.
