Experiments on two-phase swirling flow in a separator are carried out using several swirlers having different vane angles, different hub diameters and different number of vanes to seek a way for improving steam separators of uprated boiling water reactors. Ratios of the separated liquid flow rate to the total liquid flow rate, flow patterns, liquid film thicknesses and pressure drops are measured to examine the effects of swirler shape on air-water two-phase swirling annular flows in a one… 
NUMERICAL STUDY ON SWIRLING FLOW AND SEPARATION PERFORMANCE OF SWIRL VANE SEPARATOR
Full knowledge of gas-liquid flow in a swirl vane separator is essential for separator design and performance improvement. In this paper, three-dimensional numerical investigations on swirling flow
Two-phase swirling flow in the barrel of a steam separator
A downscaled model of a steam separator was used to understand the characteristics of swirling flow after passing through the first pick-off ring (POR). Main conclusions obtained were as follows: (1)
Pressure Drop in Two-Phase Swirling Flow in a Steam Separator
Pressure drop and liquid film thickness in air-water swirling flows in a one-fifth scale model of the steam separator are measured for a wide range of gas and liquid volume fluxes. Numerical
