Modelling electro-osmotic flow in porous media: a review

Purpose – This paper aims to provide a comprehensive literature review on modelling electro-osmotic flow in porous media. Design/methodology/approach – Modelling electro-osmosis in fluid systems without solid particles has been first introduced. Then, after a brief description of the existing approaches for porous media modelling, electro-osmotic flow in porous media has been considered by analysing the main contributions to the development of this topic. Findings – The analysis of literature has highlighted the absence of a universal model to analyse electroosmosis in porous media, whereas many different methods and assumptions are used. Originality/value – For the first time, the existing approaches for modelling electro-osmotic flow in porous have been collected and analysed to provide detailed indications for futureworks concerning this topic.
