Interaction of Reaction-Diffusion Fronts and Marangoni Flow on the Interface of Deep Fluid

Abstract

I consider a bistable reaction-diffusion system on the interface of deep fluid interacting with Marangoni flow. The method of matched asymptotic expansions is used to resolve the singularity at a sharp interface between the alternative states, and to compute the self-induced flow velocity advecting the domain boundary. It is shown that Marangoni flow serves as an efficient mechanism preventing the spread of the state with a higher surface tension when it is dynamically favorable.
