Nonlinear Model of Electrokinetic Phenomena in VHDL-AMS

Abstract

In this paper a new non-linear model of electrokinetic phenomena as well as results of the model simulations are presented. The origin of the model can be found in electric double layer and site binding theories, therefore the model is based on physical and physico-chemical constants such as buffer pH, zeta-potential or fluid viscosity. The model was thought as a first-attempt-model, very useful while the first stage of a new fluidic microsystem design process is being launched. Therefore it is not as precise as a 2D or 3D multidomain models, but because of implementing in VHDL-AMS language, it is fast and reliable, and also can show a global tendency of the designed microsystem behavior.
