Abstract:Analysis tools that quantify the pressure and potential changes occurring over pressure-driven electrokinetic device elements are necessary for the design of optimal laboratory-on-a-chip devices. In this study, the resistance of a nanofluidic silica channel with negatively charged walls containing a 90^{∘} bend to the electroviscous flow of a potassium chloride salt solution is quantified in terms of two equivalent lengths using numerical analysis. One equivalent length is based on the excess pressure drop and… Show more
