Transient measurement of temperature oscillation during noisy film boiling in superfluid helium II

摘要

Noisy film boiling, which is characterized by a loud noise andsevere mechanical vibra- tion, is a particular phenomenon ofsuperfluid helium ll (He ll). Experiments have been conducted un- dervarious thermal conditions by varying the heating time t and the heatflux q, and the temperature oscillation during noisy film boiling ismeasured by the superconductor temperature sensors in order tounderstand the physical mechanism of noisy film boiling.
