CHEMO-MARANGONI CONVECTION .2. NONLINEAR STABILITY ANALYSIS

A nonlinear problem on concentration-capillary instability at the interface of two liquid media in the presence of an interfacial chemical reaction of the second order has been considered. The effect of interfacial chemical reaction on the nonlinear development of interfacial instability has been studied using a finite-amplitude stability method and weak nonlinear convection pattern analysis. As has been ascertained, the incremental perturbations specifically generated by a nonlinear chemical reaction lead either to the establishment of an order space-periodic pattern or to the emergence of a chaotic flow with a sufficiently wide wave spectrum. © 1993 by Academic Press, Inc.
