Abstract


Porous Electroosmotic (EO) pump is the type of pump which contains a porous media regime to perform flow moving under electric field application. It can use a constant value of porosity with constant pore diameter limiting the flow rates especially near the wall region in addition to the boundary layer effects. In this study, a composite porous layer has been proposed to use in EO pump with a high porosity value near the wall region rather than the central region of the flow field. A 2D rectangular porous channel of 4mm×1.5mm is employed and it has been divided vertically into three major domains of variable. As a result, an appreciable increase in velocity magnitude especially near wall region but also in the central region.
