Abstract
The critical heat flux q λ at which normal-fluid (He I) sets in at the center of a heated surface distributed along the inner wall of a He II channel can be smaller than the value calculated from the theory of Gorter-Mellink heat conduction. The reduction in q λ becomes noticeable as the ratio of channel gap d to channel length L increases. The effect may be explained by the presence of a temperature gradient across the channel gap, so that the temperature at the heated side reaches the λ-point at an earlier q λ than the other side.
