Magnetic Field Effects on Electrochemical Processes:  A Theoretical Hydrodynamic Model

Abstract

The effect of a static homogeneous magnetic field that is directed parallel to the planar electrode surface is analyzed in terms of a hydrodynamic boundary layer formation and equivalent mass transfer model for a semi-infinite electrode. The model predicts the decrease of the boundary layer thickness upon increasing either the magnetic field strength, B, or reagent bulk concentration, C*, with the power dependence corresponding to C* 4/3 B 1/3 . This permits the interpretation of the enhanced mass transfer at electrode surfaces via hydrodynamic principles.
