Reflections on Some Problems Concerning the Role of Superfluid Turbulence in thePropagation of Second-Sound Pulses in He 2

摘要

A survey of the present state of knowledge about the role of superfluidturbulence in the propagation of second sound pulsers in He-2 is presented as well as the theory concerning primarily, the initial stages of heat pulse evolution. Research findings which are mostly related to overshoot effects are given. Some ad hoc experimental and theoretical checkups run to clarify some of the questions raised during the survey are also presented.
