The flow structure of a thermal counterflow jet is investigated by direct measurement of the normal fluid velocity with a laser Doppler velocimeter (LDV). The temporal and spatial variation of the normal fluid velocity is measured to investigate the detailed properties of a He II thermal counterflow
A method of flow visualization in superfluid helium has been developed by the use of solid H2-D 2 particles and hollow glass spheres as neutrally buoyant tracers to follow the normal component flow. It is applied to the study of a thermal counterflow jet based on pattern recognition of jet profiles
The Gorter-Mellink equation of steady-state heat transfer in He II is used to develop a method of calculating the peak heat flux for a magnet cooled in a bath of He II. It is shown that the equivalent thermal resistance of a series or parallel arrangement of linear cooling channels is given by ReQ =
