Electroosmotic flow of pseudoplastic nanoliquids via peristaltic pumping

Abstract

The study of electroosmotic flow of biorheological fluids has been employed in the advancement of diversified biomicrofluidics systems. To explore more in this field, a mathematical model is developed to investigate the electroosmotic flow of pseudoplastic aqueous nanoliquids in microchannel. A tangent hyperbolic fluid model is employed to describe the rheological behavior of the pseudoplastic fluid. Here, analytical solutions for potential distribution, temperature and nanoparticle fraction are derived and perturbation solution for stream function, pressure gradient and volumetric flow rate are obtained. The convective boundary condition is applied on the channel walls. The authentic assumptions of Debye-Hückel linearization, long wavelength and small Reynold's number are employed in the dimensional conservative equations. The influences of various emerging parameters are graphically computed for axial velocity, pressure gradient, thermal temperature, nanoparticle volume fraction, skin friction coefficient and Nusselt profiles. To observe the thermal radiation effects, a thermal radiative flux model is also deployed. It is noticed that the heat transfer Biot number increases with increasing thermal temperature; however, a reversed behavior is reported for the nanoparticle volume fraction. Therefore, the present model does not only provide a deep theoretical insight to interpret the electroosmotic flow systems, but it will also be applicable in designing the emerging tool for biomicrofluidic devices/systems under peristalsis mechanisms.

“…Francesko et al [19] observed the progress of LOC and microfluidics in detail. Javavel et al [20] illustrated the EOF of pseudoplastic nano liquids through peristaltic pumping. However, the above studies did not examine the electroosmotic effects in peristaltically flowing third order fluid.…”

Comparative study of hybrid nanofluids in microchannel slip flow induced by electroosmosis and peristalsis

“…Nevertheless, none of the studies focused on the combined effects of peristaltic and electroosmotic pumping processes to enhance performance efficiency of smart pumps for fulfilling the need of nanotechnology and health care. By addressing the dual benefits of both pumping mechanisms, several mathematical models [23][24][25][26][27] have been presented to analyze how electroosmosis controls/amplifies the peristaltic pumping process. Prakash and Tripathi [23] have studied radiative heat flux effects in electroosmotic driven peristaltic flow of Williamson viscoelastic ionic nanoliquids through microfluidic channels.…”
