Abstract
This review is intended to summarize the status and the open issues in the studies of boiling in saturated superfluid helium under microgravity condition. Superfluid helium has been utilized even in microgravity for cooling detectors and mirrors onboard satellites. Superfluid helium is called a quantum fluid that has many characteristic features. The heat transfer mechanism in superfluid helium due to internal convection is much different from that in ordinal fluid even in microgravity. In this review paper, the fundamental properties of superfluid and the effect of gravity upon boiling in superfluid helium will be described, and several microgravity experiments results will be reviewed. To conclude, the several numerical studies and some open issues will be summarized.
