Electrothermal transport via copper nanoparticles in a microchannel propagated by peristalsis

Abstract

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.

“…Some particular situations are taken up to verify the accuracy of our analytical results. The analytical results of [35] can be derived from our present model on substituting j = 0.4,…”

“…Only a small number of writers [30][31][32][33] have researched the effects of applied magnetic fields on a variety of fluid models, considering the broad range of applications. Initially, Chakraborty [35] examined the peristaltic motion and electroosmosis in the microchannel. Several models of peristaltic motion under electro-osmotic body force have been scrutinized for different scenarios.…”

“…In addition, Ramesh et al [43] investigated the EOF of viscoelastic fluids during peristaltic pumping. Noreen et al [35] examined the thermal effects of copper nanoparticles driven by electroosmosis and peristalsis. Noreen et al [44] investigated the impact of energy exchange on the peristaltic transport of nanofluids over microchannels.…”
