Capillary Flow Experiment

1. The primary objective of the CL unit experiments is to identify the extent the role of the boundary condition at the contact line plays in the natural dynamic response of a large capillary interface to a variety of disturbances.
2. The primary objective of the ICF units is to experimentally determine secondary imbibition rates in complex containers due to spontaneous large length scale capillary flows along interior corners in weakly 3-dimensional containers. Secondary objectives of the experiments are to quantify such flows in closed loop cycles, and to identify the passive phase separation characteristics of certain capillary driven multiphase-flows (e.g. bubbly flow) along interior corners.
3. The primary objective of the VG units is to determine equilibrium interface configurations and critical wetting conditions for interfaces between interior corners separated by a gap. A secondary objective is to validate numerical predictions of the large length scale discontinuous or nearly discontinuous wetting phenomena.
