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 and severe mechanical vibra- tion, is a particular phenomenon of superfluid helium ll (He ll). Experiments have been conducted un- der various thermal conditions by varying the heating time t and the heat flux q, and the temperature oscillation during noisy film boiling is measured by the superconductor temperature sensors in order to understand the physical mechanism of noisy film boiling.
