Suppression of electroconvective and morphological instabilities by an imposed cross flow of the electrolyte

The interaction between the electrohydrodynamic instability and an imposed flow is studied. The imposed flow distorts the concentration field causing a sheltering effect which hinders the ion transport from low to high concentration regions, and therefore suppresses the electroconvective instability below a certain wavenumber. The removal of the morphological modes resulting from the hydrodynamic instability can change the wavenumber of the unstable electrodeposition.
