Electrokinetic development length of electroviscous flow through a contraction

Joseph Berry, Malcolm Davidson, Dalton Harvie

Abstract


This study presents an analysis of the electrokinetic development length of electroviscous flow through a slit-like contraction. The effect of contraction ratio, electric double-layer thickness and wall surface charge on the electrokinetic development length of electroviscous flow is quantified. An order of magnitude expression for the electrokinetic development length is derived.
