Pinning of Water Imbibition Front In Porous Media

  • Po-Zen Wong (a1), Thomas Delker (a1), Morgan Hott (a1) and David B. Pengra (a1)


We report a study of the dynamics of capillary rise of water in a column of glass beads. The water column height h is measured as a function of time t. Analyzing the late-time data in terms of critical pinning, dh/dt α (PPa)β, we find an anomalously large exponent β. A similar measurement for contact line pinning in capillary tubes indicates β < 1. We discuss these findings in light of recent theories for domain wall pinning in the random-field Ising model and suggest a new equation of motion which corresponds to the Wolf-Villain model with quenched noise.
