摘要: Abstract Voltage-step transient problem, useful in electrodiffusion diagnostics of the near-to-wall flow kinematics, is solved for microdispersion liquids that manifest non-linear velocity profile close to wall. The known solution this problem circular probes a diffusion-layer approximation (DLA), assuming power-law representation profiles, Wein and Kovalevskaya [11] , corrected on edge effects, important at low Peclet number, i.e. small slow flows. A model process, controlled by convective diffusion finite developed here as generalization approach et al. [9] . applied treating primary voltage-step data several aqueous high-molecular polysaccharide solutions, displaying strongly profiles
