Electro-osmotic flow of a second-grade fluid in a porous microchannel subject to an AC electric field

摘要: Studies on electro-osmotic flows of various types fluids in microchannel are great importance owing to their multifold applications the transport liquids, particularly when ionized liquid with respect a charged surface presence an external electric field. In case viscoelastic fluids, volumetric flow rate differs significantly from that Newtonian even takes place under same pressure gradient and With this end view, paper is devoted study concerning pattern porous microchannel, which action alternating The influence rheological parameters, e.g., Reynolds number, Debye-Huckel parameter, shape factor fluid viscoelasticity kinematics fluid, has been investigated for secondgrade fluid. problem first treated by using analytical methods, but quantitative estimates obtained numerically help software MATHEMATICA. results presented here applicable cases where channel height much greater than thickness electrical double layer comprising Stern diffuse layers. reveals larger value parameter creates sharper profile near wall also velocity increases as permeability enhanced. further shows dominates at lower values number. will be quite useful validate observations experimental investigations characteristics complex numerical models necessary deal more realistic situations, come into picture, blood micro-circulatory system subject
