WebJan 1, 2015 · Capillary Spreading. Another variant of the surface-tension-driven flow that is of potential interest to the microfluidics research community is the capillary-spreading phenomenon. Of particular interest can be the spreading of liquids on rough homogeneous substrates or on heterogeneous substrates with hydrophobic and hydrophilic stripes. WebJun 17, 2016 · The rate of spreading or retraction of a drop on a flat substrate is determined through a balance of surface tension and hydrodynamic flow. While asymptotic regimes are known, no general rate equation has hitherto been available. Here, we revisit this classic problem, in a regime governed by capillary and vi
