Mechanical, chemical, and electrical constraints and hydrodynamic interfacial instability
Abstract
Threshold conditions are derived for the onset of convection in infinite plane and spherical surfaces with chemical, mechanical, and electrical constraints. A linear stability analysis is used and the role of the following factors is discussed: diffusion coefficients, viscosity coefficients, surface chemical processes, the adsorption-desorption step, the surface activity, the surface charge and the surface electric potential, interactions between surface charges, and interactions between surface dipoles in crude models of biosurfaces. New varieties of instabilities appear owing to the coupling between chemical, hydrodynamical, and electrical processes.
