Thermal Oscillation Anomalous Heat Transport Characteristics in Saturated- He II Channels

The thermal oscillation in the near-saturated He II transports the work through channels above the critical heat flux qc of the phase transition. The oscillation does not entirely destroy the temperature distribution in the vortex state built at qc. Therefore the additional heat input above qc may be efficiently converted into the work flow superimposed on heat conduction, The characteristic frequencies of the thermal oscillation are discriminated by means of an oscillatory disk and a microphone. The thermal oscillation is dominated by the channel length reflecting the nature of the wave.
