Utilizing the alternating environment of short-term reduced,super- and normal-gravity provided by a reduced gravity airplane,two-phase water-air flow patterns both in the first visible stage of a static membrane separator and in the recycled water line are studied experimentally in the present paper.Unsteady intermittent rivulet flow with variable mass flux is observed in the variable cross-section serpentine flow channel in the first visible stage,which exhibits the same characteristics in different gravity.Finely bubble flow and slug flow with mach large averaged space between air bubbles are observed in the recycled water line.Although much large fluctuation of void fraction is obvious in the recycled water line,the general characteristics is irrelative with the gravity.Thus,the performance of the separator is not dependent upon the gravity
