Impact of an Electric Field on the Buyoancy Instability of an Autocatalytic Reaction Front in a Narrow Cell
Original language description
The paper presents results of experimental studies of action of the electric field on the velocity and stability of the traveling fronts. The studies were performed in a quasi 2-dimensional (Hele-Shaw) cell made of two glass plates separated by a teflonspacer. One of the glass plates was coated with conductive 25 nm indium-thin-oxide (ITO) layer. The electrodes (5 mm wide strips) were made in this coating by etching. In our experiments the reaction begins on the cathode, where a pair of an ascending and descending fronts is formed. Due to the density gradient arising across the reaction fronts as a result of composition changes, the ascending front becomes unstable a forms so called "fingers". An electric field applied across the Hele-Shaw cell will be shown to stabilize ascending fronts when the positive electrode is placed above the front.
