Název v původním jazyce

Non-equilibrium modeling of AC electroosmosis in microfluidic channels - parametrical studies

Popis výsledku v původním jazyce

This non-equilibrium mathematical model based on the balances of mass, momentum and ionic components and the Poisson equation has been developed. The model describes transport processes in the entire time and space domains including electric double layers. We assume that the system works below the electrochemical limit. The electroosmotic transport in various microfluidic channels is studied. It is considered that the channels contain a periodically repeating spatial motif. Hence the transport processesare studied in one periodic segment of the channels. Non-planar asymmetric electrodes, on which an AC electric field is imposed, are deposited on one channel wall. The model equations are solved using the finite element software COMSOL. In order to carry out the numerical simulations, a strongly anisotropic mesh of finite elements is developed. The stable periodic regimes are obtained by the time-integration of the model equations. In this work, we focus on: (i) parametric analysis of t
