Pressure drop and void fraction of two-phase helium flowing in horizontal tubes.

Summary

The slip ratio (the ratio of the velocity of the gaseous phase over that of the liquid phase) in two-phase helium is found to be always greater than unity and to decrease towards unity with increasing mass flow rate and increasing system pressure. The mass flow rate does not appear to have an effect on the two-phase frictional multiplier. A slight tube size effect on the two-phase pressure drop multiplier is found at 1.2 atmosphere; however, this effect quickly diminishes as the system pressure reduces.
