Gas and liquid phases are easily separated owing to buoyancy on the ground. However, in space (i.e. under micro-gravity condition), the method cannot be adopted. In this study, a method of a Y-junction by using the difference of inertia force between gas and liquid phases is proposed for a first-step and rough separation. Experiments of phase separation in a horizontally placed impacting Y-junction were carried out under both normal and micro-gravity conditions. Phase separations in Y-junction for two-component and one-component two-phase flow were also examined. As a result, it was shown that the liquid could be extracted effectively from the two-phase flow by using a Y-junction under micro-gravity. The effect of inlet flow pattern of gas-liquid flow on phase separation performance was discussed.
