| Description
| - Spatially two-dimensional nonequilibrium mathematical model describing electroosmotic flow through a submicrometer channel with an electric charge fixed on the channel walls is presented. This system is governed by the hydrodynamic, electrostatic, and mass transport phenomena. The model is based on the coupled mass balances, Poisson, Navier?Stokes, and Nernst?Planck equations. Nonslip boundary conditions are employed. The effect of an imposed electric field on the system behavior is studied by means of a numerical analysis of the model equations. We have obtained the following findings. If the channel width is comparable to the thickness of the electric double layer, the system behaves as an ion-exchange membrane and the dependence of the electric current passing through the channel on the applied voltage is strongly nonlinear. In the case of negatively (positively) charged walls, a narrow region of very low conductivity (so-called ionic gate) is formed in the free electrolyte near the channel

- Prostorově dvourozměrný matematický model popisující tok submikronovým kanálem s povrchově fixovaným elektrickým nábojem byl zkoumán.Byl sestrojen a analyzován nerovnovážný Navier-Stokes-Poisson-Nernst-Planckův model elektroosmotického toku. Byl studován vliv vnějšího elektrického pole na chování systému. Závislost iproudových a rychlostních charakteristik na řadě modelových parametrů byly sestrojeny. (cs)
