In order to develop a phase separation technique under microgravity condition, the method of the impacting Y-junction by utilizing the difference of inertia force between gas and liquid phases is proposed. The experiments for phase separation in the impacting T (θ=90°) and Y (θ=30°)junctions of 10.5 mm ID set in a horizontal plane were carried out under microgravity condition. Gaseous nitrogen - water, and fluorocarbon FC72 were used as the working fluids. Under the microgravity condition by parabolic trajectory frights of an airplane, the phase separation performance was measured by controlling the extraction rate. As a result, it was shown that the liquid extraction from two-phase flow was possible by Y-junction under microgravity.
