In order to investigate the flow and hydrodynamic characteristics of two-phase flow influenced by the change in gravity, tests were performed using MU-300 flight capable of producing μg and 2g conditions and on ground with the identical flow conditions and the same flow loop. The test section was a 10mm diameter and 600mm lengths, and it was also mounted horizontally to the direction of gravitational force. The ranges of superficial velocity are 0.1m/s to 2.6m/s for water, 0.03m/s to 21m/s for air, respectively. The data collected at three gravity levels (μg, 1g and 2g) were compared with the existing models and correlations, and the differences and similarities between the two-phase flow characteristics at three gravity levels were also presented.
