The purpose of this study is to develop phase separation equipment using a simple impacting T or Y-junction for gas-liquid two-phase flow under microgravity. In order to clarify the effect of tube diameter on the phase separation performance, phase separation experiments in the T (θ=90°) and Y (θ=60°, 30°) junctions of 4 mm ID set in a horizontal plane were carried out using air and water as the working fluids. Moreover, the effect of the flow direction of the inlet flow was evaluated. The phase separation performance was also improved by decreasing of the angle θ between the inlet and the side branch as well as our previous results on junction of 10 mm ID. However, phase separation was not performed for the high gas velocity condition in which the inlet flow regime was an annular flow.
