Recently, a two-phase thermal control system has been proposed to increasing the output power of large artificial satellites and space stations. For such a system, it will be important to establish a phase separation technique of a gas-liquid two-phase flow. In this paper, an impacting T-junction is proposed as the phase separation technique under microgravity. Ground experiments were first performed to clarify the phase separation characteristics. From the experiments, it was found that the inlet flow pattern and liquid velocity affected the phase separation most and that phase separation for stratified and wavy flow regions was difficult. Moreover, to verify the applicability of the T-junction under microgravity, experiments utilizing parabolic-trajectory flights were also performed. As a result, it was shown that the T-junction is an effective device for roughly separating gas and liquid under microgravity.
