Abstract
Persistent current states in superfluid helium contained in a rotating superleak are studied for various velocities and initial conditions. The change in the superfluid component velocity as the normal component velocity changes is interpreted in terms of a circulation-free potential flow and the entrance of vortices. The appearance of vortices of opposite sign to that of preexisting ones in the superleak is discussed and this is related to the history-dependent nature of persistent currents. An analogy between a superfluid helium system such as ours and a highly irreversible type-II superconductor is made.
