Abstract
Transient heat transfer on a flat plate in subcooled He II produced by stepwise heat inputs was measured for the bulk liquid temperatures ranging from 1.8 to 2.1 K at atmospheric pressure. Four test plates with the same dimensions were used. To see the effect of expansion on heat flow, one of them is supported in a pool of subcooled He II and other three are located on one end of rectangular ducts with various cross sections. Other ends of the ducts are opened to a pool of pressurized He II.
The transient heat transfer is such that the quasi-steady state exists with a certain lifetime, t L , and rapidly changes to film boiling regime after the depletion of lifetime. The lifetime is shorter for higher value of the step height.
The values of t L on the flat plates in the ducts with the ratio of cross sectional duct area to the heater area, A d /A h , higher than unity agree well with the values for the duct with A d /A h = 1 for q s higher than a certain value. With the decrease of q s from the value, they become longer than the values for A d / A h =1. This trend is more significant for the ducts with higher values of A d / A h . Correlation of lifetime based on the two fluid model is given.
