摘要
Film boiling modes in both subcooled and saturated He II were experimentally investigated. It was found that there were two film boiling modes clearly bounded by a line just above the lambda pressure (p(lambda)). The one is a typical subcooled film boiling mode that normally appears at still higher pressure than p(lambda). The other film boiling mode resembles noisy film boiling in saturated He II. It is found that in the vicinity of the region of the lambda point or the lower heat flux, noisy film boiling does not occur and subcooled region directly connects with silent film boiling one.
