Animation of the large-amplitude "slamming" oscillations at Re=250, T=21, corresponding to the time-traces shown in Figs. 7 and 8 in the paper. The movie identifies several key features of the flow: The rapid deceleration of the flow in the downstream rigid section during "slamming"; the disturbances downstream of the collapsible section; and the presence of higher-frequency waves in the collapsible section.
