Bubbles dispersed in liquid are easily separable by gravity-induced buoyanc
y on the earth. In microgravity environment, however, the other external fo
rces should be utilized to separate bubbles in liquids because the gravitat
ional force does not work. Centrifugal force is frequently applied as exter
nal force for separation of a small density difference mixture on the earth
. The gas-liquid system has large density difference, the gas-liquid separa
tion by centrifugal force is considered effective under low gravity conditi
ons. In this study, two types of centrifugal gas-liquid separation systems
were investigated under low gravity conditions. (C) 2000 Elsevier Science B
