Flow and solute transport in dissolutive wetting

Liquid spreading on a soluble substrate is known as dissolutive wetting, common phenomenon in the medical and industrial fields. However, dynamic process of wetting not fully understood due to complex transport mass momentum. In this article, we present hydrodynamic model that accounts for both Marangoni buoyancy effects analyze interface shape, flow, solute wetting. Based our theoretical analysis experiments, propose two dimensionless numbers, Ya Pe′, plot phase diagram We investigate evolution flow field, concentration solid–liquid shape different types Furthermore, discovered new type resulting from competition between convection buoyancy, using experimental approaches. Our study provides significant insight into which may has applications joining processes materials, material synthesis, structural fabrication, so on.
