Effect of baffles on inflow patterns in spherical containers during weightlessness

An experimental investigation of isothermal liquid inflow patterns in a spherical container during weightlessness was conducted in a 2.2-Second Zero-Gravity Facility. The test liquids employed exhibited an essentially zero-degree static contact angle on the surface of the container. Qualitative results are presented for both baffled and unbaffled containers describing the uniformity of tank wall wetting and the liquid loss through two symmetrically located vents.
