LIQUID-VAPOR INTERFACE CONFIGURATION IN ANNULAR CYLINDERS

摘要

As a part of the general study of liquid behavior in a reduced-gravity environment, an experimental investigation was conducted to determine the static equilibrium configura¬tion of liquids contained in annular cylinders. The static contact angle between the test liquid and the container wall was restricted to 0°. The experiments were conducted in zero and low gravity such that the Bond numbers were 0 and 3. The shape of the liquid-vapor interface in annular cylinders is presented as a function of the annulus ratio and the Bond number.
