This communication investigates the simultaneous impact of the magnetic field, heat absorption and mixed convection in electroosmotically induced peristaltic flow of copper particles in the blood. The two-phase flow model is used in the microchannel with flexible walls. The thermal features of nanofluids are studied using copper nanoparticles. The Poisson-Boltzmann equation is employed to accommodate the electrical double layer in the microchannel. With Debye-Hückel, lubrication and long wavelength approximations, the problem becomes non-dimensional. Exact solutions have been calculated for velocity, stream function, pressure rise, pressure gradient and heat transfer coefficient and temperature profile. Impact of different embedded parameters on flow properties is graphically illustrated. It is found that the electroosmotic parameter strongly effects the velocity profile and bolus formation. Also, the decreasing behavior of temperature is presented, which clarifies the nanofluid as a cooling agent. The results show an increment in peristaltic pumping with rise in mixed convection while it decreases with magnetic field. Furthermore, a comparative study of pure blood and copper blood is conducted. The obtained results may be suitable in the peristaltic pump modulation for the efficient operation of a variety of industrial, biomedical and drug delivery systems in the microfluidic device.

“…In the above appraised papers, most of the analyses have covered separately either peristaltic motion through nanofluid flow or flow of a hybrid nanofluid; however, comparatively few analyses have investigated simultaneously hybrid nanofluids in peristaltic motion. The various models of hybrid nanofluids discussed by various researchers, such as different shapes of nanofluids, 36,37 copper–water nanofluid, 38‐40 and the Cu–CuO/blood model 41 flow driven by peristaltic pumping, have been presented to discuss the Newtonian/non‐Newtonian effects on flow and pumping characteristics. The rational flow is a special kind of characteristic which contains the nonsymmetrical stress tensor employed for polar fluids.…”

Contraction and expansion play a crucial role in biomedical applications, such as heart pumping, ovum in the feminine fallopian vessel, blood fluid transport, and so forth. Inspired by these features, the present effort concentrates on the consequences of a thermal slip in the peristalsis of Cu/blood and Cu-CuO/blood nanofluids in asymmetric flow formation. Hence, the microrotation influence of blood flow is considered here. Heat transported through the channel due to perpendicular flow buoyancy effects is also studied. The special effects of thermal radiation, nanoparticle shape, and heat source/sink parameters on the flow are studied in the proposed model. The MATLAB BVP4c condition is utilized to achieve the numerical solutions of the transformed system of nonlinear coupled differential equations. The most important outcome of the present analysis is an enhancement in the evaluation study of the Cu/blood and Cu-CuO/blood nanofluids on the axial velocity, axial spin velocity, pressure gradient, and temperature distributions in the asymmetric channel. Also, another important outcome is observed that the Cu-CuO blood nanofluid strongly has dominated the Cu/blood nanofluid in axial spin velocity.

Electrokineticmicroperistaltic pumps are important biomechanical devices that help in targeted drugging of sick body parts. This article is focused on mathematical modeling and analysis of some important aspect of such flows in a rectangular duct with wall properties. Effects of zeta potential, heat source, and deby length are also studied. Carbon nanotubes (CNTs) in the Newtonian base fluid are assumed as drugging material. A comparison of single‐walled CNTs and multiwalled CNTs is also presented. It is considered that the walls are flexible and encapsulating the region with limited permeability. The defined flow problem is modeled and analyzed analytically for the transport of CNT–water nanofluid. It is accepted that the flow is steady, nonturbulent, and propagating waves do have a considerably longer wavelength when compared to amplitude. The conditions and assumptions lead to a model of coupled partial differential equations of order two. The exact results using the eigenfunction expansion method are procured and shown accordingly. The predictions about the behavior of important parameters are displayed for single‐walled CNT and multiwalled CNT—water nanofluidic behavior—using figures. The impact of sundry parametersis are analyzed. The application of the current study involved a transporting/targeted drug delivery system using peristaltic micropumps and magnetic fields in pharmacological engineering.
