Superfluid helium is considered as one of the possible coolants for the cooling of a superconductive magnet. It is therefore necessary to study the heat transfer between the magnet and superfluid helium, particularly the removal of the high-density heat generated when the magnet is quenched. The purpose of this study is to investigate the transient heat transfer of saturated superfluid helium in a Gorter-Mellink Duct. Numerical simulation of temperature transient in the duct is performed by using basic equations of the two fluid model, with the Gorter-Mellink term added to deal with the mutual friction between super-and normal-fluid components. The results indicate different patterns of thermal wave propagation for stepwise inputs of different heat fluxes． The results are also compared with the experimental data by Van Sciver, with the agreement being satisfactory.
