Abstract

Transient heat transfer caused by large stepwise heat inputs to a flat plate was measured in subcooled He II at atmospheric pressure for bulk liquid temperatures ranging from 1.9 to 2.1 K. The flat plate was made of Manganin, one side insulated, 10.3 mm in width, 40 mm in length and 0.1 mm in thickness. Steady-state heat transfer and its critical heat flux were also measured by using quasi-steadily increasing heat inputs for the same experimental conditions. The steady-state critical heat fluxes for the liquid temperatures were well expressed by the authors’ correlation based on the Gorter-Mellink equations. The lifetime of quasi-steady heat flux in Kapitza conductance regime, which corresponds to that of a certain point on the extrapolation of steady-state Kapitza conductance curve, was systematically measured: the quasi-steady state rapidly changes to film boiling regime after the depletion of lifetime. Comparisons of the results on the flat plate with those on the horizontal wires with the diameters ranging from 0.08 to 0.7 mm under the same condition already reported by the authors were made to clarify the effect of heater shape.
