- Capillary Rise under Microgravity in Variously-Shaped Capillary Glass Tubes
説明
Water movement plays an important role to grow crops under microgravity. Previous research reported that water hardly moved in porous media whereas water in capillary tubes rose to the top of the tubes under microgravity. Another study reported that water hardly moved on concave surfaces under microgravity. Our objective of this study was to evaluate the effects of surface shape and junction of capillary tubes on water movement driven by the capillary force under microgravity. We used several shapes of tube (straight, concave-convex, wide-narrow, narrow-wide, Y-shaped, T-shaped and spiral) and observed water movement in the tubes during drop–tower induced microgravity. Water in concave–convex, wide–narrow tubes moved beyond concave and convex surfaces under microgravity. Water in narrow–wide tubes, however, stopped on their concave surfaces. In the Y- and T-shaped glass tubes, water movement was restricted after the junction of glass tubes by viscous force.
