Influence of interfacial electrokinetic on MHD radiative nanofluid flow in a permeable microchannel with Brownian motion and thermophoresis effects

Abstract

In this study, the behavior of a microchannel flow is examined. The fluid is considered to be a nanofluid, which moves between two parallel flat plates in the presence of an electrical double layer. The Buongiorno nanofluid is considered with body force. In this study, the unphysical supposition presented in the preceding work to the discontinuity of the flow fled where the electrostatic potential in the central of the canal must be equal to zero is removed. The incorrect supposition that the pressure constant is preserved, which is considered a known form, is corrected. The current fresh model equation is modified by using dimensionless parameters to convert partial differential equations into ordinary differential equations. The transformed nonlinear equations are solved by the homotopy analysis method. The physical parameters, magnetic parameters, Eckert number, Lewis number, Brownian motion parameters, thermophoresis parameters, and Prandtl number are analyzed. The influence of both the viscous and Joule dissipation in the presence of magnetohydrodynamic effect is examined.

Analysis of Fractional Bioconvection with Hybrid Nanoparticles in Channel Flow

“…Rafique et al [27] defined the Casson nanofluid flow over a slanted permeable inclined surface with energy and mass transport. Khan et al [28] discussed the effects of interfacial electro kinetic MHD radiative nanofluids flow on porous microchannels by thermophoresis and Brownian movement impacts. Ali Lund et al [29] conferred hybrid nanofluid on the nonlinear contracting sheet with double branches of an MHD three-dimensional pivoting stream.…”

Analysis of micro-motion of nanofluid particles based on machine vision

“…Most common particle distribution functions are two-parameter distribution functions. The so-called dual parameter means that the function can be determined by two specific parameters, one is the characteristic size parameter characterizing the particle size of the particle group, and the other is the distribution parameter characterizing the particle size distribution of the particle group [10]. Some powders produced by aerosol and precipitation methods have a particle number distribution that approximately conforms to this distribution, as:…”

Significance of Stefan blowing effect on flow and heat transfer of Casson nanofluid over a moving thin needle

“…Hussain and Ahmed [11] studied the flow of liquid through a porous enclosure by using Buongiorno's nanofluid model. Khan et al [12] scrutinized the Brownian motion and thermophoresis effects on nanoliquid stream through a microchannel with a radiation effect. Jayadevamurthy et al [13] explicated the bioconvective stream of hybrid nanofluid through a moving rotating disk by considering thermophoresis and Brownian motion effects.…”
