Spreading of Water: Condensation Effects

摘要: Although the macroscopic, bulk behavior of liquids wetting (or dewetting) can be adequately explained by viscous flow, intricate details near solid/liquid/fluid triple line (TL) are still not totally appreciated.These two aspects correspond to bases hydrodynamic approach and molecular kinetics approach, respectively, explain spreading. We have suggested a complementary model that kinetics, based on modified curvature dynamic, meniscus TL, which leads local condensation vapor from surrounding atmosphere, further contributing motion. An earlier paper dealt with whose thin film (i.e., TL) is dominated long-range van der Waals forces. Here, we turn our attention spreading water. Basic equations allow for non-negligible slope then applied water, consisting different, thickness dependent, disjoining pressure isotherms.
