...M. Abdelgawad; I. Hassan; N. Esmail; P. Phutthavong The viscous micropump consists of a cylinder placed eccentrically inside a microchannel, where the rotor axis is perpendicular to the channel axis. When the cylinder rotates, a net force is transferred to the fluid because of the unequal shear...
