Vortex nucleation, transition to turbulence, and cavitation: “system failure” experiments in liquid helium and extreme value statistics

It is suggested that recent experiments in liquid helium, like single vortex nucleation, transition to turbulent flow around a sphere at a critical velocity, and cavitation of the liquid in a sound wave belong to the type of “system failure” experiments which is well known in reliability testing and...

Description
Summary:It is suggested that recent experiments in liquid helium, like single vortex nucleation, transition to turbulent flow around a sphere at a critical velocity, and cavitation of the liquid in a sound wave belong to the type of “system failure” experiments which is well known in reliability testing and whose statistical properties are described by extreme value statistics. This leads to far reaching consequences for the interpretation of the critical velocities and of the voltage threshold for cavitation.
