Thermophoresis and Brownian Motion Effects on Magnetohydrodynamics Electro-Osmotic Jeffrey Nanofluid Peristaltic Flow in Asymmetric Rotating Microchannel

Abstract

This article investigates with the thermophoresis and Brownian motion effects on MHD electro-osmotic Jeffrey nanofluid peristaltic flow in an asymmetric microchannel. Well established large wavelength and small Reynolds number approximations are invoked. Numerical solutions have been evaluated for the stream function, nanofluid velocity, nanofluid temperature and nanoparticle phenomena. The computed results for nanofluid velocity, temperature, and concentration fields are utilized to determine the skin-friction, Nusselt number, and Sherwood number. The graphical results have been presented and discussed for various involved parameters. The novel features of nanofluids made them potentially significant in heat and mass transfer mechanism occurring in medical and industrial processes like microelectronics, pharmaceutical processes, hybrid engines, thermal management of vehicles, refrigerator, chiller, gas temperature reduction and so forth. These processes bear tendency to enhance thermal conductivity and the convective heat transfer more efficiently than base fluid. This unique aspect made nanofluids the topic of interest in recent time via different fluid flow models. The problem at hand is one such application of nanofluids in peristaltic flow through the asymmetric rotating microchannel.

Influence of variable velocity slip condition and activation energy on MHD peristaltic flow of Prandtl nanofluid through a non-uniform channel

“…The slip velocity is considered in some studies because of its importance in artificial heart valves. Supplementary, see 1 , 6 , 10 , 26 – 28 . In the current study, the variable slip velocity is studied to assure its significant role in heart valves 49 , 50 .…”

Role of electromagnetic analysis in radiative immiscible Newtonian and non‐Newtonian fluids through a microchannel with chemical reactions

“…Sun et al 24 discussed the entropy generation of electroosmotic flow in a rectangular rotating microchannel in the presence of viscous dissipation, Joule heating, and heat convection and found that zeta potential shows an inverse relation with the Nusselt number. Reddy and Makinde 25 investigated the MHD electroosmotic peristaltic flow of a Jeffrey nanofluid in an asymmetric microchannel with the influence of Brownian motion and the thermophoresis effect and observed that the electroosmotic parameter increases the temperature profiles of the fluid.…”

Study of Double Diffusivity and Heat Conducting Phenomena under the Casson Nanofluid Flowing through a Vertical Peristaltic Tube

“…Saravana et al [27] explored the effect of an aligned magnetic field and cross-diffusion on the Casson fluid. Also, the peristaltic flow of Jaffery nanofluid was examined by Reddy et al [28] to explore the impact of Brownian and thermophoresis movement on MHD flow. It elaborates that the unique characteristics of nanofluids make them potentially important in mass and heat transfer phenomena happening in industrial and medical processes including pharmaceutical processes, hybrid engines, microelectronics, refrigerators, chillers and so on.…”
