The purpose of the work is to study the dynamics and transport properties of liquids in small volumes, bounded by surfaces with a specially organized heterogeneity, or in volumes with homogeneous surfaces in which the heterogeneity of the flow occurs due to ultrasound. The main objectives of the proposed study are the development of the theory of rapid mixing of solutions in small volumes when the electric current passes through microchannels or ultrasound effects on them, the study of electrohydrodynamic processes and mass transfer, which accompany the passage of electric current through a channel with heterogeneity of the surface charge, and an analysis of the possibilities of manufacturing microchannels from superficial charge of optimal morphology using the Langmuir-Blodget technique. The research method is theoretical approaches of physicochemical electro-hydrodynamics (Nernst-Planck equation, Navier-Stokes equation, continuity, convective diffusion, approximation of local equilibrium and local electroneutrality, cell model) combining macroscopic electrodynamics, classical hydrodynamics and thermodynamics of irreversible processes , computer simulation.
