Moving Helium Film Measurements

MEASUREMENTS on the profile of the moving helium film by Gribbon and Jackson 1 have given qualitative, but not quantitative, support to Kontorovich's theory 2 of the moving film. This theory was based on the postulates of the two-fluid model of liquid helium, and it predicted that the moving fi...

Description
Summary:MEASUREMENTS on the profile of the moving helium film by Gribbon and Jackson 1 have given qualitative, but not quantitative, support to Kontorovich's theory 2 of the moving film. This theory was based on the postulates of the two-fluid model of liquid helium, and it predicted that the moving film would be thinner than the static film, while an alternative theory by Franchetti 3 predicted a thicker moving film. Tilley 4 has reconciled the two approaches using arguments based on the thermodynamics of a system in which relative motion occurs and has confirmed Kontorovich's result. Recently Franchetti 5 has proposed several reasons for the contradiction between the measurements and the simple theory.
