Abstract
This paper studies the stability of the front of chemoconvective finger patterns spontaneously formed in a two-layer system of reacting liquids placed in a narrow gap between two solid plates. The mathematical model of this process includes a system of equations that take into account chemical reaction, diffusion, and convection, written in the Hele-Shaw approximation. Numerical analysis of the model shows that with increasing intensity of heat release, the envelope of the salt fingers is smoothed and chemoconvection occurs in a narrow region adjacent to the interface.
