Theoretical Framework Links Three-Fluid Junctions to Young's Law in Wetting

A new theoretical study introduces a continuum construction that connects the Neumann balance at three-fluid junctions to Young's law, which describes wetting phenomena on rigid solids. This framework clarifies how a local Neumann-like ridge can coexist with a Young angle measured against a distant wall, differentiating geometric convergence from the influence of migration and reaction forces.
