In order to predict various phenomena related to flow and heat transfer in space, it is necessary to carry out experiments under microgravity. The present report deals with the characteristics of a gas-liquid two-phase flow under microgravity utilizing parabolic trajectory flights. The experiment was carried out in a horizontal transparent acrylic resin tube of 10.5 mm I. D. and 500 mm length, using gaseous N2 and water as the working fluid, in a superficial gas velocity range of 0.025m/s to 4.6m/s and superficial water velocity range of 0.062m/s to 0.35m/s. The flow pattern, pressure drop and void fraction obtained in the microgravity experiment were compared with the results in the ground test, and also with other experimental results obtained under normal gravity. As a result, the two-phase frictional multiplier could be expressed by correlation of φ2L=1+16/X+1/X2 using the Martinelli parameter X.
