Abstract

Experiments were conducted to test the theoretical prediction that smooth super-to-subcritical transitions are possible via a nodal point singularity. A collapsible tube was machined to have a linear variation in wall thickness for which the theory would predict a smooth acceleration to supercritical speed, followed by a nodal point deceleration back to subcritical speed. Although quantitative agreement was not good, the experimental results provide qualitative confirmation of a smooth super-to-subcritical transition.
