Stratified two-phase superfluid helium flow.
Author(s) : ROUSSET B., GRIMAUD L., GAUTHIER A., DELHAYE J. M.
Summary
Experiments were conducted with saturated superfluid helium. Two-phase co-current stratified flow was circulated through a 40-mm inner diameter, 86-m long heated tube, with a slope of 1.4%. Mass flow rates and temperatures ranged between 1.5 and 6.3 g/s, and 1.8 and 2 K, respectively. A full description of the flow was obtained by measuring mass flow rate, quality, void fraction, wetted surface and pressure losses by means of specific diagnostics. The paper presents the physical basis of a one-dimensional two-fluid stratified flow model, adapted for adiabatic or diabatic superfluid helium flow.
