摘要: Marangoni migration of a single droplet in an unbounded viscous fluid under the additional effect variable surface viscosity is studied. The tension and depend on concentration dissolved species. Cases motion induced by presence point source given constant gradient are considered. dependence velocity governing parameters computed quasi-stationary approximation. weak advective transport studied making use singular perturbations Peclet number, Pe. It shown that, when time dependent Basset-type history term appears expansion and, as result, leading order correction to flow O(Pe1/2). If active substance driving steady, convective weaker.
