文摘

A free energy-minimizing simulation that allows computation of the shapes of sessile liquid drops on chemically patterned surfaces is described. A set of nondimensional results for drops on surfaces with a single wetting stripe is presented. Quantitative agreement is found with published experimental data for drops on many-striped surfaces, and a simple model for anisotropic wetting is evaluated.
