Peristaltic motion of MHD nanofluid in an asymmetric micro-channel with Joule heating, wall flexibility and different zeta potential

Abstract

A mathematical scrutiny is introduced for the flow of magneto-hydrodynamic nanofluid through an asymmetric microfluidic channel under an applied axial electric field. The impacts of wall flexibility, Joule heating and upper/lower wall zeta potentials are considered. Electric potential expressions can be modeled in terms of an ionic Nernst-Planck equation, Poisson-Boltzmann equation and Debye length approximation. Appropriate boundary conditions have been utilized to get the results of highly nonlinear coupled PDEs numerically. The impact of physical factors on the characteristics of flow, pumping, trapping and heat transfer has been pointed out. The outcomes may well assist in designing the organ-on-a-chip like gadgets.

“…Waheed et al [33] inspected the effect of heat and mass for third-order fluid via peristaltic microchannel. Noreen et al [34] proposed the transportation of MHD nanofluid via peristaltic asymmetric microchannel. Prakash et al [35] studied the impact of heat transfer in peristaltic transportation of nanofluids via microchannel.…”

Entropy generation in MHD nanofluid flow with heat source/sink

“…The initial approximations, linear operators and auxiliary parameters are chosen such that Eqs. (22) and (23) have a solution at each point of ∈ [0, 1] . Using Taylor's series and Eq.…”

“…Dogonchi et al [21] analysis of MHD nanofluid flow in a porous canal took the thermal radiation effect into account and found an inverse relationship between the radiation and the temperature profile. Noreen et al [22] found that velocity increases in the center of the channel where electroosmotic parameters have been reduced during a microchannel MHD nanofluid flow study. Ma et al [23] studied the hybrid nanofluid flow on a channel and found that the Reynolds number significantly affected the velocity distribution.…”

Soret‐Dufour effects in electroosmotic biorheological flow of Jeffrey fluid

“…Entropy generation was examined by Noreen et al 17 for Carreau fluid in a peristaltic microchannel. Waheed et al 18 worked on the Joule heating for peristaltically flowing MHD nanofluid. The analysis on heat transfer for the peristaltic pumping was done by Noreen and Tripathi 19 in non‐Darcy medium.…”
