| Outline of Final Research Achievements |
Water behavior in porous media under microgravity has not been elucidated yet. Our objectives were to elucidate water infiltration and the applicability of the capillary rise theory under microgravity. We conducted experiments on capillary rise and water infiltration into porous bodies under a μG environment made by parabolic flights by aircraft and free fall by a falling tower. Based on a series of experiments, applicability of the capillary rise theory to microgravity was confirmed. However, it was revealed that water transfer was inhibited when a large inner diameter capillary tube was connected to a small inner diameter capillary tube. It was found that moisture infiltration into porous media was significantly inhibited under microgravity.
