Note (General)
It is well known that some material scientific and biological experiments came out to be a failure due to the neglect of wetting phenomena at the liquid (molten material)-solid (container material) interfaces on space. Thus, it is required to estimate the gravitational effects on the wetting behavior between the liquid-solid interface. Though many attempts had been tried to evaluate precisely the value of the static wetting phenomena on the ground, the dynamical and statical wetting problems on space had remained unsolved. So in this report, the wettability on the liquid-solid interface considering the gravitational effects and the dynamical conditions by liquid bridge method are discussed. The experimental results were evaluated from the liquid bridge shapes and the contact angles using an aircraft in parabolic flight. The liquid bridge shapes were observed by CCD video recording system and analyzed by using the technique of digital image acquisition and processing.
