摘要：

An experimental study was carried out on the heat transfer properties of pressurized superfluid helium in the Gorter-Mellink heat transfer region. By using channels of hydraulic diameter from 5.6 x 10(-5) through 4.81 x 10(-3) m, the heat transfer properties of pressurized superfluid helium were measured in the experiment. The temperature dependence of Gorter-Mellink parameter, AGM, is revealed from the experimental results. It is also proven that A(GM) depend only on temperature, and not on the channel size and shape. The effect of quantized vortices on heat transfer of pressurized superfluid helium is discussed in comparison of the channel diameter with the mean vortex line spacing.
