Electro-osmosis modulated peristaltic flow of non-Newtonian liquid via a microchannel and variable liquid properties

A theoretical model is developed to stimulate electrokinetic transfer through peristaltic movement in a microchannel. The effect of variable viscosity, variable thermal conductivity, and wall properties is carried out. Such flows emerge in bio-mimetic pumping systems at the extremely tiny scale of significance in physiological operation, e.g., eye medication shipment systems. The sinusoidal wave-like motion propagates along the channel wall leading to the peristaltic motion. The long-wavelength and petite Reynolds number estimations are supposed to abbreviate the governing formulas. Debye–Hückel linearization is also analyzed. The variable thermal conductivity and variable viscosity parameters are used as perturbation parameters. The graphical outcomes are presented for temperature, velocity, concentration, and streamlines. Biomedical engineers can use the obtained results to create bio-microfluidic mechanisms that may assist in carrying physical liquids.
