Mathematical modeling of AC electroosmosis in microuidic and nanouidic chips using equilibrium and non-equilibrium approaches

Popis výsledku v původním jazyce

AC electroosmoticmicropumps are suggested to be powerful tools for electrolyte dosing in various microand nanouidic systems. In this paper, we compare two modeling approaches for studying the AC electroosmosis in the following micro and nanochannel systems: (i) a traveling-wave AC pump with a spatially continuous wave of electric potential applied on a planar boundary, (ii) a traveling-wave AC pump with a wave of electric potential applied on a set of discrete planar electrodes, and (iii) an AC pump with a set of non-planar electrodes. The equilibrium approach is based on the use of capacitor?resistor boundary conditions for electric potential and the slip boundary conditions for velocity at electrode surfaces. The non-equilibrium approach uses the mathematical model based on the Poisson equation and the non-slip boundary conditions. We have observed discrepancies between the predictions given by the bothmodels and then we have identied their possible reasons. The comparison of the equ
