Summary

Single-phase helium II was circulated through a 28-mm internal diameter tube, over a length of 200 m for mass flow rates between 0.02 and 0.1 kg/s. Steady-state pressure drop measurements allow the authors to estimate the friction factor for Reynolds numbers in the 1-million range. Rectangular heat pulses were applied at mid-length, and the fluid temperature was measured at several locations along the flow. A code has been developed which uses the two-fluid model. Simulation results are in good agreement with experimental measurements.
