Parabolic flight experiments on fluid surfaces and wetting

During parabolic flights of a KC-135 aircraft, experiments were performed on the behaviors of water, gylcerine, and Fluorinert in different containers. Results are presented from studies of liquid menisci in solid edges, the formation of solid edges with differing dihedral angles using arrays of microscope slides and rosette modules, the spreading of water and glycerine in rosette modules, and wetting dynamics. Other studies include contact angles in reduced gravity, liquid menisci in prisms, spreading and breakage in rhombic prisms and circular cylinders, liquid rings around conical rods, and wetting of a cylindrical annulus and close-paced spheres.
